OBJECTIVE To describe the spectrum of Magnetic Resonance spectroscopy in focal brain lesions and determine its diagnostic accuracy using histopathology as gold standard in differentiating neoplastic and non-neoplastic focal brain lesions. METHODS The study was conducted in Department of Radiology, Aga Khan University Hospital, Karachi from Dec 2006 till Jan 2009. Fifty three patients found to...
Here we present the case of a 30-year-old man diagnosed with a dysgerminoma with mediastinal involvement, who developed an isolated chylopericardium during treatment. The purpose of this paper is to review the etiology, diagnosis and new approaches to the treatment of chylopericardium.
Studies over many years have suggested that increased polyamine synthesis may be necessary for neoplastic growth. This review summarizes recent work on the regulation of putrescine production both de novo and via the degradation of higher polyamines and provides a summary of studies using transgenic mice in which the levels of proteins that regulate these processes (L-ornithine decarboxylase, a...
BACKGROUND Neoplastic meningitis is a complication of solid and hematological malignancies. It consists of the spread of malignant cells to the leptomeninges and subarachnoid space and their dissemination within the cerebrospinal fluid. METHODS A literature review was conducted to summarize the clinical presentation, differential diagnosis, laboratory values, and imaging findings of neoplasti...
Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic chang...
