ABSTRACT
To assess the role*of MRI in differentiation between usual and unusual cerebellopontine angle [CPA] lesions.The study was conducted on 40 patients with signs and symptoms pointing to CPA lesions and subjectedto MRI examination.MRI showed usual lesions such as Schwannoma in 14 patients and meningioma in eight patients. Lessfrequent lesions include glomus tumour in five patients and chordoma in five patients. Unusual lesions such asepidermoid cyst, arachnoid cyst, ependymoma, medulloblastoma, expophytic glioma, papillary adenocarcinoma ofendolymphatic sac, metastatic adenocarcinoma and atherosclerotic basilar artery in one patient for each entity.MRI could differentiate between usual and unusual lesions by proper identification of the site, extentand signal characteristic of each lesion

The activity of the monocyte phagocytic system in children with rheumatic heart disease [RHD], their parents, their normal siblings and in nonrheumatic families was investigated. Phagocytic activity of isolated monocytes was assessed using luminol-dependent chemiluminescence. The count per minute of emitted light was measured before and after stimulation with zymosan solution. The results indicate that one-third of the siblings of children with RHD were genetically free while two-thirds, as well as the parents, were heterozygous, and that children with RHD were homozygous for [a] mutant gene[s] responsible for the defective function of the monocyte phagocytic system. The findings are strongly suggestive of autosomal recessive inheritance
