1/3. Haemangiopericytoma of the trigeminal nerve.A 41-year-old man presented with a 4-year history of progressive right-sided diplopia on lateral gaze and right nasolabial paraesthesia. A CT revealed minor bone erosion of Meckel's cave and of the right petrous apex by a uniformly enhancing lesion at the base of the skull. magnetic resonance imaging on three occasions over 2 years showed tumour, measuring 4 cm in diameter, with features suggestive of a trigeminal neuroma. At surgery the lesion had the macroscopic appearance of a giant schwannoma. Histopathological findings were that of a meningeal haemangiopericytoma (HPC) of the trigeminal nerve. Intracranial HPC are rare and aggressive tumours of the central nervous system. They usually arise from the falx, tentorium and dural sinuses. The present case is unique as it originates from a cranial nerve.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/3. Thrombosed giant intracavernous aneurysm with subsequent spontaneous ipsilateral carotid artery occlusion.We report a case of a 47-year-old man with a giant thrombosed aneurysm of the right cavernous internal carotid artery who initially presented with headache, double vision and trigeminal numbness. He experienced subsequent asymtomatic proximal occlusion of the parent vessel, revealed by follow-up angiography. This case illustrates the possibility that a giant thrombosed aneurysm may exert enough compression upon the parent vessel to induce flow stasis with resultant intraluminal thrombosis progressing to occlude the entire parent artery.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
3/3. The reawakening of a sleeping little giant.This case report and literature review highlights the classical signs and symptoms of herpes zoster infection involving the trigeminal nerve. Incorrect diagnosis leads to delay in providing effective treatment and could result in failure to identify potentially hazardous ocular complications and to prevent chronic post-herpetic pain.- - - - - - - - - - ranking = 4keywords = giant (Clic here for more details about this article) |
