ANSWER
The image reveals a hypodense extra-axial fluid collection in the right frontoparietal region, measuring 8 to 10 mm in diameter. There is some mass effect and evidence of right-to-left shift. These findings are consistent with a subacute subdural hematoma, possibly secondary to the patient’s anticoagulant use. (The patient later recalled bumping his head a couple of months prior—but that may have been incidental.)
Arrangements were made for him at a local hospital where neurosurgical services were available. He underwent successful evacuation and was subsequently symptom free.
