Development of dural plasmacytoma after evacuation of chronic subdural hematoma: Case report

T2 weighted images show an iso- or hyperintense lesion compared to gray matter while diffusion is usually restricted, with hypersignal on DWI and hyposignal on the ADC-map. Since these imaging findings are non-specific and dural plasmacytoma has no pathognomonic clinical properties, definite diagnosis is based on histopathology [1]. According to a study by Schwartz et al., these numbers are completely different in case of cranial localization of SPB or SEP, with 100% of cases of cranial localized SPB developing a multiple myeloma, and none of the cranially localized SEP [9].\n More likely, however, the subdural hematoma itself or drainage thereof in a patient with a known monoclonal gammopathy might have led to the dissemination of lymphocytic cells in the subdural region resulting in the formation of a rapidly growing plasmacytoma of the plasmablastoma variety.
