Giant cerebral cavernoma is a rare malformation classified as a brain occult vascular lesion. We report a case of initially misdiagnosed giant cavernous angioma revealed by a spontaneous intracerebral hemorrhage. A 40-year-old woman was admitted with right hemiplegia and altered consciousness occurring 3 days prior to presentation. A non-contrast CT scan showed a left parietal gross hematoma, a...

BACKGROUND AND PURPOSE A cavernous angioma is a developmental vascular malformation with a high risk of hemorrhage. The purpose of this work was to retrospectively determine whether an MR sign of T1 hyperintense perilesional signal intensity is useful for the differentiation of cavernous angioma from other hemorrhagic cerebral masses. MATERIALS AND METHODS The institutional review board appro...

Littoral cell angioma is a rare vascular tumor of the spleen. The pathogenesis is unknown but the lesion is associated with several malignancies and immunological disorders. The diagnosis requires histopathological examination. The malignant potential of this lesion is unknown, which is why splenectomy is recommend for all cases. Symptomatic cases generally suffer from hypersplenism and pyrexia...

Sturge-Weber syndrome (SWS), or encephalotrigeminal angiomatosis, is the most frequent neurocutaneous syndrome, characterised by vascular malformations which manifest sporadically. The full presentation includes brain vascular malformations (pial or leptomeningeal angioma), cutaneous abnormalities (facial angioma) and ocular abnormalities (choroidal angioma). We present the case of a patient wi...

BACKGROUND AND PURPOSE We used L-[1-(11) C]leucine (LEU) positron emission tomography (PET) to measure amino acid uptake in children with Sturge-Weber syndrome (SWS), and to relate amino acid uptake measures with glucose metabolism. METHODS LEU and 2-deoxy-2[(18) F]fluoro-D-glucose (FDG) PET were performed in 7 children (age: 5 months-13 years) with unilateral SWS. Asymmetries of LEU uptake i...

Extracerebral cavernous angioma is a rare entity; only 45 cases have been reported [1-32] . Thirty-seven of the angiomas, including the two cases reported here, were found in the parasellar region of the middle cranial fossa [1-26] . Differentiation from parasellar meningioma is known to be difficult, since the CT findings are similar. We report the MR findings in two cases of extracerebral cav...

Littoral-cell angioma (LCA), a primary angioma which clinically belongs to splenic hemangioma, can be mostly found in normal spleen red sinus shore cells of reticuloendothelial cell system. The cells of LCA strongly express endothelial and tissue cell associated antigens that indicate a dual differentiation characteristic; whereas only endothelial cell markers are positive in normal spleen red ...

Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occurred in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic fin...

That cerebral angiomata may simulate migraine is well known but the frequency of such a mode of presentation is not clearly established (Mackenzie, 1954). In the last 10 years many patients with migraine have been investigated by carotid angiography in the Royal Infirmary, Manchester, but very few have been shown to harbour an angioma. This has led to the impression that the relationship betwee...
