[Meningeal metastasis of malignant melanoma].
Two woman patients with malignant melanoma of the skin known from their case history and with acutely emerging neurological symptoms were examined both by CT and by MR tomography (both plain and with intravenous contrast medium). The radiologically derived suspicion of meningioma could not be confirmed by intraoperatively performed histological examination. In both cases the patients had meningeal melanoma metastases with low melanin content and without noticeable bleeding into the metastases. MR diagnosis is rendered difficult by the absence of paramagnetic substances typical of melanoma metastases. Hence, if the case history is known, it should be considered whether there is meningeal metastasising with atypical histology.
