ABSTRACT

Diagnosis: Acute on chronic bilateral subdural hematomas.

History: Recent onset gait disturbance and history of 2 falls in the past 6 weeks.

Findings: Non-contrast CT of the brain demonstrates bilateral frontal subdural hemorrhages of varying chronicity. The right collection contains some prominent areas of high density, consistent with acute on-chronic hemorrhage. The left collection also contains a small amount of high density that may also represent acute blood. Overall, these collections are roughly symmetric in size and cause no midline shift. There is no hydrocephaplus; the ventricular systems are smaller than expected for age, perhaps secondary to compression by the extraaxial fluid collections.

Ddx: Acute on chronic bilateral subdural hematomas.

Dxhow: Diagnosis confirmed by imaging.

No MeSH data available.


Noncontrast CT of the brain demonstrates bilateral acute-on-chronic subdural hematomas. The higher density collections generally correspond to the acute portions of the hemorrhage. However, patients on anticoagulant therapy may completely lack the ability to form a clot, which is the hyperdensity we see on CT.  In these patients, the acute portion of the hemorrhage may be hypodense.
