Foster-Kennedy syndrome caused by solitary intracranial plasmacytoma.

The first case of typical Foster-Kennedy syndrome, including decreased olfaction of the side of the optic atrophy due to a primary solitary intracranial extraskeletal plasmacytoma, is reported. Its appearance on a computed tomography scan was compatible with a meningioma or subdural hematoma. The patient demonstrated a chronic, corticosteroid-sensitive, relapsing optic neuropathy associated with an elevated sedimentation rate and a monoclonal gammopathy.

Choroid plexus carcinoma.

The authors report a case of carcinoma of the choroid plexus and review the 22 cases reported since 1844 that adhere to the criteria for primary choroid plexus carcinoma. Two-thirds of the tumors are found in children and all of these are located in the lateral ventricles. In adults most of the tumors are present in the fourth ventricle.
