ABSTRACT

Diagnosis: 1) Acute hemorrhagic infarct 2) Subependymoma, lateral ventricle

History: This pt is a 71 y/o male with a long hx of high blood pressure and chronic atrial fibrillation who presented with sudden onset of rectal bleeding, disorientation, slurred speech, and generalized muscle weakness L>R.

Findings: A non-contrast CT of the head demonstrates areas of low-intensity representing acute infarcts in the right frontal and temporal areas (in the region of the MCA) and also in the right posterior parietal area (in the region of the PCA). Also of note are small areas of higher intensity (white) within the infarcted areas, denoting hemorrhages. Edema of the right hemisphere is demonstrated by the loss of normal architecture, including loss of sulci and flattening of the gyri. A large mass is seen in the right lateral ventricle. This mass was resected and found to be an approximately 4.2 x 2.3 x 1.9 cm subependymoma upon pathological examination. Post-surgical MR images demonstrate previous infarct and surgical changes most notable as a defect in the anterior corpus callosum

Ddx: The differential diagnosis for a lateral ventricular mass in an adult includes: <li> metastatic carcinoma or melanoma <li> central neurocytoma <li> subependymoma <li> subependymal giant cell astrocytoma <li> meningioma <li> ganglion cell tumor In a child <li> choroid plexus papilloma <li> choroid plexus carcinoma

Dxhow: Pathological examination which showed scattered foci of nuclei in a dense fibrillary background, mild nuclear pleomorphism, and rare mitotic figures. Histology and staining patterns were consistent with the diagnosis of subependymoma.

Exam: Gen: Disorientated by generally friendly and conversant elderly male; CV: a-fib; Rectal: grossly bloodly stool; Neuro: disoriented to time and place, generalized muscular weakness, L>R.

No MeSH data available.
