Primary Non-Hodgkin’s lymphoma of the scalp and cranial vault mimicking enplaque meningioma – A case report

Abstract

Primary Non-Hodgkin's lymphoma of the cranial scalp and skull vault is an uncommon cancer. We describe a similar incidence in a 40-year-old female. She had a widespread growth on the left side of her head that had been growing in size for three months. There was a widespread swelling in the left parietal and occipital region of the scalp on local examination. A contrast-enhancing tumor emerging from the left parieto-occipital bone with surrounding dura was seen on imaging. The lesion involves both the marrow and the cortex, with infiltration of the neighboring dura and a large subgaleal component, resembling an enplaque meningioma. The patient had craniotomy and lesion removal. Histopathology revealed non-Hodgkin's lymphoma with a preference for diffuse large B cell lymphoma.
