Diffuse villous hyperplasia of choroid plexus.

Diffuse villous hyperplasia of choroid plexus (DVHCP) is a rare condition which is characterized by the presence of diffuse enlargement of the entire choroid plexus throughout the length of the choroidal fissure and overproduction of CSF. The diagnosis of diffuse villous hyperplasia of choroid plexus can be established by the MR demonstration of diffusely large, contrast enhanced choroid plexus in the cases of overproduction hydrocephalus. Although some authors recommend choroid plexus excision or coagulation, ventriculo-atrial shunt insertion is a simple and effective treatment modality in cases of diffuse villous hyperplasia of the choroid plexus. In this report we present a case of diffuse villous hyperplasia of the choroid plexus and a short review of the literature. To our knowledge, in the CT and MRI era only 5 cases of DVHCP cases have been reported.

Non-traumatic intradiploic arachnoid cyst.

In this report, we present a case of non-traumatic intradiploic arachnoid cyst in a 65 year-old woman with a slow growing swelling in the right frontotemporal region without a history of head trauma, which was diagnosed intra-operatively. Extradural intracranial location of non-traumatic arachnoid cyst is a rare clinical entity with a few reported cases in the literature. Characteristic features of non-traumatic intradiploic arachnoid cysts are also described in this mini-review article.

Aspergillus pituitary abscess.

BACKGROUND: Pituitary abscess is rare and most of the cases are of bacterial origin. True fungal pituitary abscess is extremely rare only five cases have been reported. In this report, we present a case of aspergillus pituitary abscess. Mortality rate in intracranial aspergillosis is close to 100% especially in immunsuppressed patients when undiagnosed and untreated. In focal CNS aspergillosis total cure can be achieved in approximately 30% of the cases by surgical drainage and intensive antifungal therapy. Although this is the first reported case with magnetic resonance imaging examination the definitive diagnosis was established only by histopathological examination. CLINICAL PRESENTATION: A 42 year-old man was referred to our hospital with the diagnosis of sellar suprasellar mass accompanied by frontal headache and decreased visual acuity. His medical history was insignificant. Physical examination was normal and the patient was afebrile. The neurological examination revealed bilateral papilledema and bitemporal hemianopsia but no stiff neck and motor or sensory deficit. In the light of MRI examination, the preoperative diagnosis was pituitary abscess secondary to paranasal sinus infection or hemorrhagic pituitary adenoma. INTERVENTION: The patient was successfully treated by transsphenoidal surgery. Histopathological examination of sphenoid sinus mucosa revealed normal mucosal appearance with inflammation and histopathological examination of the intrasellar mass resulted in the diagnosis of aspergillosis. All cultures obtained from sphenoid sinus were reported as having no growth. However in the second week after the operation fungal culture of the intrasellar mass grew aspergillus. After 8 weeks of amphothericine-B treatment, the patient was discharged. At the last follow up examination two years after the operation, the patient was symptom free with normal pituitary function. CONCLUSION: Aspergillus pituitary abscess should be considered in the differential diagnosis of a pituitary mass. The correct diagnosis of pituitary aspergillosis can only be achieved by histopathological examination because clinical and radiological findings including MRI are not specific and culture results are obtained later. Immediately after the diagnosis, intensive antifungal therapy should be started for a successful treatment.

Angiotensin-converting enzyme inhibitor cilazapril prevents chronic morphologic vasospasm in rat.

It has been shown that a long-acting angiotensin-converting enzyme inhibitor cilazapril prevents morphologic changes in arteries secondary to hypertension and endothelial damage, which are analogous to the changes in cerebral arteries following subarachnoid hemorrhage. In this study, the effect of cilazapril on chronic vasospasm was investigated on the rat femoral artery vasospasm model, and morphometric analyses were performed. Animals were divided into three groups. In group 1, femoral arteries were removed after cardiac perfusion. In groups 2 and 3, right femoral arteries were exposed to 0.1 mL autologous whole blood and wrapped with silastic cuff. Animals in group 3 received cilazapril (10 mg/kg) for 7 consecutive days. After the perfusion-fixation, femoral arteries were examined by light and transmission electron microscopy and processed for morphometric analysis. Vessels from animals in group 2 showed a significant luminal narrowing and morphologic changes throughout the vessel wall, while vessels from animals treated with cilazapril appeared nearly normal. These results suggest that cilazapril may be effective in the prevention of chronic vasospasm.
