Non-Hodgkin Lymphoma Mimicking Chronic Subdural Hematoma: Case Report

A 67-year-old white female patient with a history of behavioral change and chronic headache. There was an episode of traumatic brain injury episode 4 months ago. At admission, she was in Glasgow for 15, with no focal neurological deficits. Magnetic resonance imaging showed hypo-intense concave-convex subdural collection in T1 and T2; the MR was not performed with contrast. Magnetic resonance imaging showed hypointense concave-convex subdural collection. In the intraoperative period, a mass was evidenced, and biopsy material was collected. The histo-pathology result revealed a non-Hodgkin’s B-cell lymphoma. We report the case to highlight the importance of performing biopsy when the something unusual is identified during surgery, mostly when the lesion can lead to a disease with other treatment than surgery alone. It’s importante to the surgical team that the MRI may not safely differentiate between chronic subdural hematoma and other subdural lesions, so we must have as differential diagnosis of subdural lesions also lymphomas.
