we describe a 40-year-old woman presenting with headache, nausea, episodic amnesia and blurred optic disc. brain mri disclosed diffuse leptomeningeal enhancement. csf analysis showed aseptic meningitis with elevated ace level. neurosarcoidosis was diagnosed based on granulomatosis changes on tissue biopsy.

background & objectives: the accurate assessment of the diseased tissue is fundamental to the diagnosis and management of disorders of the central nervous system (cns). the ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of cns tumors. the aim of our study was to evaluate the accuracy of squash preparation in diagnosing cns tumors by comparing wit...

noncoding ribonucleic acids micro-rna is involved in the regulation of gene expression have major roles in the post-transcriptional level. a micro-rna alone several causes down regulation of mrna transcript of the target. thus, small changes in the expression of a micro rna may lead to significant changes in gene expression are different. micro- rna as key regulators of immune cell lineage diff...
