A case of cystic form of angiomatous meningioma with prominent microvascular pattern mimicking haemangioblastoma.
A surgical case was reported of an unusual angiomatous variant of meningioma with predominant microvascular component and extensive cystic changes. The tumour was incidentally detected in a 79-year-old woman who was admitted to the hospital because of a head injury. The CT scan revealed in addition to bilateral subdural haematomas a large-sized (5 x 5 x 4 cm) multicystic tumour with a solid contrast-enhancing nodule in the right frontal region. Microscopically, the tumour tissue was composed predominantly of a dense meshwork of small, capillary-like and thin-walled dilated blood vessels and a relatively small component of intervening meningotheliomatous tumour cells. The resemblance of the presented case to some rare cases of cystic meningioma which were formerly classified as a haemangioblastic variant of meningioma or transitional forms between meningioma and haemangioblastoma is briefly discussed.
