Metastasis from ovarian carcinoma

CLINICAL HISTORY:
This 55-year old patient was operated upon three years ago for an ovarian carcinoma. Now she presents with an epileptic seizure. She complains of a few months of headaches.

NEUROLOGICAL EXAMINATION is noncontributory.

MRI:
a) TRANSAXIAL T2-WEIGHTED (2500/90/1) SPIN-ECHO SEQUENCE (IMAGES 1 AND 2): A huge inhomogeneously hypointense mass (arrowheads) within the trigone of the right lateral ventricle. The midline is displaced.

b) TRANSAXIAL T1-WEIGHTED (600/20/1) SPIN-ECHO SEQUENCE (IMAGES 3 AND 4): The mass is inhomogeneously hyperintense.

c) TRANSAXIAL (IMAGES 5 AND 6) AND CORONAL (IMAGE 7) GADOLINIUM-ENHANCED SPIN-ECHO SEQUENCES: Possibly some enhancement is noted at the periphery of the tumor. Note the extension of the lesion within the corpus callosum (arrowheads) and the supratentorial hydrocephalus.

RADIOLOGICAL DIAGNOSIS is metastasis from ovarian carcinoma. Shortening of T1 and T2 is frequently seen in metastasis from ovarian carcinoma, malignant melanoma and metastasis from mucinous adenocarcinoma of the gastrointestinal tract.

No surgical or pathological confirmation is available.
