Failure to Diagnose Subdural Hematoma Medical Malpractice in Chicago

A subdural hematoma is one of the most time-sensitive brain emergencies a doctor can encounter. When a Chicago personal injury lawyer reviews these cases, the same pattern appears repeatedly: a patient came to the emergency room with clear warning signs, and the doctor sent them home without ordering a CT scan. Hours or days later, that patient suffered permanent brain damage or died. If that happened to someone you love, you may have a medical malpractice claim under Illinois law.

What a Subdural Hematoma Is and Why a Missed Diagnosis Is So Dangerous

A subdural hematoma (SDH) is a collection of blood that forms between the dura mater, the brain’s tough outer covering, and the arachnoid layer beneath it. As blood accumulates, pressure builds inside the skull. The condition can present acutely, subacutely, or chronically, with severity ranging from asymptomatic minor bleeding to life-threatening increases in intracranial pressure, herniation, and long-term neurocognitive impairment.

There are two main types doctors encounter. An acute subdural hematoma develops rapidly after a severe head injury and is often a medical emergency. A chronic subdural hematoma forms slowly over days or weeks after minor trauma, and its symptoms can be subtle and easily overlooked. The chronic form is especially dangerous in older patients because it can be dismissed as simple confusion or age-related decline.

In a stable patient with subtle gait or cognitive change after a fall, a low threshold for imaging should be maintained, because chronic subdural hematoma is common, treatable, and frequently overlooked when the presentation is framed as simple deconditioning or confusion. That is a failure of clinical judgment, and it can cost a patient everything.

The incidence of SDH is notably higher in the elderly population, a demographic trend partly attributed to increased vascular fragility and brain atrophy. These physiological changes predispose older adults to SDH, even following minor head impacts. Patients on blood thinners face even greater risk. When an emergency room physician or primary care doctor fails to account for these risk factors, the consequences are often irreversible.

Prompt recognition, accurate diagnosis through imaging and laboratory evaluation, and timely intervention, whether medical stabilization or neurosurgical evacuation, remain critical to preventing secondary injury and optimizing outcomes. A delay of even a few hours can mean the difference between a full recovery and permanent disability.

Warning Signs Doctors Should Never Ignore in an SDH Patient

Recognizing a subdural hematoma requires paying attention to a specific cluster of symptoms. Acute symptoms cluster around raised intracranial pressure and focal compression. Headache, nausea, vomiting, somnolence, aphasia, hemiparesis, gaze deviation, and progressive decline in Glasgow Coma Scale score are typical. These are not vague complaints. Each one is a red flag that should prompt immediate imaging.

Patients with subdural hematoma present with symptoms including confusion or altered mental status, decreased consciousness, weakness or numbness on one side of the body, headache, seizure, and difficulty with speech, swallowing, or walking. Any patient presenting to a Chicago-area emergency room, whether at Northwestern Memorial near Streeterville, Rush University Medical Center near the Illinois Medical District, or a community hospital in Wicker Park or Pilsen, with these symptoms after a head injury deserves immediate evaluation.

A declining Glasgow Coma Scale score, new anisocoria, worsening hemiparesis, recurrent emesis, or refractory severe headache in any patient with known or suspected subdural hematoma should be treated as evidence of progression until imaging proves otherwise. A physician who documents these findings and still fails to order a CT scan has likely breached the standard of care.

Chronic SDH presents its own diagnostic trap. The clinical presentation can vary significantly, making timely diagnosis challenging, particularly in elderly patients who may present with non-specific symptoms such as confusion, gait instability, or subtle changes in mental status. Doctors who treat these symptoms as psychiatric or age-related issues without ruling out an intracranial bleed are making a serious clinical error.

Once symptoms are present, the diagnostic pathway is straightforward. A CT scan or MRI is often used to detect the presence of a subdural hematoma. It may require emergency surgery to drain blood, or remove coagulated blood pressing on the brain. Ordering that scan is basic medicine. Skipping it is negligence.

How Failure to Diagnose a Subdural Hematoma Becomes Medical Malpractice in Illinois

Not every bad medical outcome is malpractice. To have a valid claim in Illinois, your attorney must show that the doctor or hospital deviated from the accepted standard of care and that this deviation directly caused your harm. Think of the standard of care as the level of skill and attention a competent doctor in the same specialty would have provided under similar circumstances.

In SDH cases, a medical malpractice lawyer will look at whether the provider failed to order imaging after a head injury, dismissed warning symptoms without investigation, misread CT scan results, or failed to consult a neurosurgeon when the situation demanded it. In an analysis of 314 SDH malpractice cases, the most common reason for litigation was negligent care in a healthcare setting resulting in SDH (55.4%), followed by failure to diagnose (47.1%). Trauma was the most common cause of SDH at 74.8%. The most frequently cited defendants were emergency medicine physicians at 76.4%.

Illinois law adds a procedural requirement before you can even file. Under 735 ILCS 5/2-622, known as the Healing Art Malpractice statute, a plaintiff must attach an affidavit to the complaint stating that a qualified health professional has reviewed the case and determined there is a reasonable and meritorious cause of action. That reviewing professional must have practiced or taught in the same area of medicine within the last six years and must be qualified by experience or demonstrated competence in the subject. The written report must accompany the affidavit. Missing this requirement can get your case dismissed before it ever begins.

Illinois also follows a modified joint and several liability rule under 735 ILCS 5/2-1117. All defendants found liable are jointly and severally liable for a plaintiff’s past and future medical expenses. A defendant whose share of fault is 25% or greater is also jointly and severally liable for all other damages. This matters when multiple providers, such as an ER physician, a radiologist, and a hospital system, all contributed to the missed diagnosis.

A medical malpractice attorney can identify every party whose negligence contributed to the harm and pursue each one appropriately under Illinois law.

Illinois Filing Deadlines for Subdural Hematoma Malpractice Claims

Time limits are one of the most critical factors in any Illinois medical malpractice case. Miss the deadline and you lose your right to sue, no matter how strong your evidence is. Under 735 ILCS 5/13-212(a), an Illinois medical malpractice action generally must be brought within two years after the claimant knew, or through reasonable diligence should have known, of the injury or death for which damages are sought. In most Illinois medical malpractice cases, the deadline is two years from when the patient knew or reasonably should have known of the injury and its connection to medical care, but there is usually a four-year outside limit from the act or omission.

The discovery rule matters in SDH cases because some patients, especially those with chronic subdural hematomas, may not immediately connect their symptoms to a doctor’s failure. The Illinois Supreme Court in Moon v. Rhode (2016 IL 119572) confirmed that discovery requires dual knowledge. Awareness of an adverse medical outcome alone is insufficient; the limitations period begins only when the plaintiff has reason to connect the injury to negligent medical care.

The four-year outer limit, called the statute of repose, is absolute in most adult cases. The Illinois statute of repose imposes an absolute deadline: no medical malpractice action can be brought more than four years after the date on which the alleged act or omission occurred. After four years from the date of the malpractice, claims are barred regardless of when the injury was discovered.

Children get more time. For minors, 735 ILCS 5/13-212(b) allows more time: generally up to eight years after the act or omission, but not after the minor’s 22nd birthday. This is important in pediatric SDH cases, including those involving birth injuries or abusive head trauma.

If a provider intentionally concealed the negligence, under 735 ILCS 5/13-215, if a healthcare provider intentionally hides wrongdoing, victims have five years from the time they discover the fraudulent concealment to file a lawsuit. Do not wait to find out which rule applies to your situation. Contact Briskman Briskman & Greenberg at (312) 222-0010 as soon as possible.

What Compensation You Can Pursue and How Attorney Fees Work in Illinois

A successful subdural hematoma malpractice claim can include compensation for past and future medical bills, lost wages, loss of earning capacity, rehabilitation costs, and pain and suffering. If the victim died from the missed diagnosis, family members may bring a wrongful death claim under the Illinois Wrongful Death Act (740 ILCS 180) and a survival action under 755 ILCS 5/27-6 to recover damages the deceased would have been entitled to pursue.

Illinois does not cap compensatory damages in medical malpractice cases for adults. Under 735 ILCS 5/2-1115, punitive damages are not allowed in healing art malpractice cases, but there is no statutory limit on economic damages such as medical expenses and lost income, or on non-economic damages such as pain and suffering. This means the full scope of your losses can be presented to a jury.

Attorney fees in Illinois medical malpractice cases are governed by 735 ILCS 5/2-1114, which caps contingent fees at 33 1/3% of all sums recovered. Briskman Briskman & Greenberg handles these cases on a contingency fee basis, meaning you pay no attorney fees unless compensation is recovered. You should be aware, however, that clients may still be responsible for certain case costs and expenses, and those details will be explained clearly during your consultation.

FAQs About Failure to Diagnose Subdural Hematoma Medical Malpractice in Chicago

How do I know if a doctor’s failure to diagnose a subdural hematoma qualifies as malpractice?

The key question is whether the doctor deviated from the accepted standard of care. If a competent physician in the same specialty, given the same patient presentation and symptoms, would have ordered imaging or taken further action, and your doctor did not, that deviation may constitute malpractice. You also need to show that the failure caused your harm, meaning that earlier diagnosis and treatment would have led to a better outcome. An attorney can connect you with qualified medical experts who can evaluate whether those elements are present in your case.

What if the subdural hematoma was caused by a minor fall and the doctor thought it was not serious?

The severity of the trauma does not determine the severity of the bleed. Chronic subdural hematomas frequently develop after minor impacts, particularly in elderly patients and those on blood thinners. A doctor who dismisses head injury symptoms without ordering a CT scan, simply because the fall seemed minor, may still have breached the standard of care. The obligation is to rule out a serious intracranial injury, not to assume one did not occur based on the mechanism of injury alone.

How long do I have to file a subdural hematoma malpractice claim in Illinois?

Under 735 ILCS 5/13-212(a), adults generally have two years from the date they knew or reasonably should have known that a medical error caused their injury. There is also a four-year statute of repose that bars claims regardless of discovery, measured from the date of the negligent act. For minors, 735 ILCS 5/13-212(b) provides up to eight years from the act of negligence, but no claim may be filed after the person’s 22nd birthday. Because these deadlines are strict, you should contact an attorney as soon as possible.

Can I sue both the individual doctor and the hospital for failing to diagnose a subdural hematoma?

Yes. Multiple parties can be liable in an SDH malpractice case. The treating physician, the radiologist who read or failed to read the imaging, the hospital or medical facility, and even a nursing staff member who failed to escalate a patient’s deteriorating condition may all bear responsibility. Under 735 ILCS 5/2-1117, defendants whose share of fault is 25% or greater are jointly and severally liable for all damages, including non-economic damages. An attorney can identify every responsible party and pursue each one appropriately.
