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...

A case of new onset migraine is described following a pontine bleed from a cavernous angioma.

Angioblastoma is a rare, benign vascular tumour composed of undifferentiated mesenchymal cells with a tendency to form lumina. This entity was first described by Nakagawa in 1949 as angioblastoma, and Wilson Jones was the first to use the term "tufted angioma" in 1976. Tufted angiomas usually occur in infancy and spread slowly. This report describes lesions from the right side of the forehead, ...
