Multiple intraparenchymal brain plasmacytomas with spontaneous intratumoral hemorrhage.

The case of a patient with two intraparenchymal brain plasmacytomas without cranial or dural attachment and with intratumoral hemorrhage is presented. Computed tomographic (CT) findings are described. Autopsy revealed two discrete intraparenchymal plasmacytomas with intratumoral hemorrhage, one cerebral and one cerebellar. There have been few case reports of brain plasmacytoma without cranial or dural attachment, and this case of multiple such intracranial, intraparenchymal plasmacytomas with hemorrhage is certainly unique. Intratumoral hemorrhage with intracranial plasmacytoma is extraordinarily rare. The literature of intracranial involvement with myeloma and plasmacytoma and the CT appearance of intracranial plasmacytoma are surveyed.
