Case 1

submitted by:
Daniel J. Brat
Emory University Hospital
Atlanta, Georgia

Clinical Summary:

Over a period of 6 months, a 31-year-old female developed headaches, nausea and vomiting and experienced short periods of unconsciousness. An MRI scan revealed a homogeneously contrast-enhancing tumor in the third ventricle, measuring 3 cm in greatest diameter, which appeared to arise in the hypothalamic/suprasellar region.

Clinical Summary:

A 37-year-old-woman was evaluated two days after a seizure. A large, intra-axial, non-enhancing mass was found in the left frontal lobe.

Case 3

Clinical Summary:

A 1-year-old Caucasian female presented with a seizure. Neurological examination showed no deficits. Magnetic resonance imaging (MRI) of the brain showed a large cystic lesion with contrast enhancement in the right temporal lobe. She underwent a right temporal craniotomy and gross total resection of the lesion, which intraoperatively appeared to have a distinct margin with the surrounding brain. She did not receive any postoperative chemotherapy or radiation therapy. Two years postoperative she is seizure-free, has no focal deficits, and has no evidence of tumor recurrence.

Case 4

Gregory N. Fuller
Anderson Cancer Center
Houston, Texas

Clinical Summary:

In the late summer of 2002 a 71-year-old man with a history of myelodysplasia five months out from a matched unrelated donor stem cell transplant developed progressively increasing weakness and was noted to have a fever of 38.3°C. The patient had been receiving regular blood product transfusions for anemia and thrombocytopenia. He was admitted to an outside hospital for presumed infection and was started on multiple antibiotics. Following several family-witnessed seizure-like episodes the patient was started on phenytoin and transferred to MDACC. Upon admission, an EEG showed marked diffuse generalized slowing that was non-reactive to exogenous stimulation, consistent with severe encephalopathy. An MRI showed multiple bright signal intensities on T2-weighted and FLAIR sequences throughout the brain stem, including the medulla, pons and midbrain. Lumbar puncture showed normal glucose with elevated protein (147 mg per deciliter). A Gram stain for bacteria, India ink preparation for cryptococcus and bacterial cultures were negative. Serum samples were sent to the CDC for viral pathogen PCR testing. The patient developed progressive liver failure, attributed to graft-versus-host disease, and became increasingly obtunded. He died one week after admission and an autopsy was performed.

Case 5

Anthony T. Yachnis
University of Florida Medical College
Gainesville, Florida

Clinical Summary:

The patient is a 1-year-old male who presented with failure to thrive and recent onset of vomiting. His weight was in the 10 percentile on admission despite an apparently normal caloric intake. Birth history was unremarkable. Imaging studies revealed a 3.3 x 2.4-cm contrast-enhancing mass in the region of the hypothalamus and optic chiasm. A bifrontal craniotomy was performed and extensive internal debulking of the mass was accomplished by a transventricular approach.
