We report a rare occurrence of an intraparenchymal plasmocytoma. On th
e past history of a severe head injury twenty years ago and the presen
ce of a porencephalic area on the computerized tomography scan and mag
netic resonance imaging we suspected a possible trauma-tumor relation.
Accuracy of the histological diagnosis of plasmocytoma was confirmed.
The treatment was a surgical excision only, and after a 4.5 years fol
low-up period, no clinical nor radiographic recurrence was noted.
