Multiple system atrophy (MSA) is an adult onset, progressive, idiopathic neurodegenerative disease that clinically manifest as MSA-C with cerebellar signs predominant, MSA-P with Parkinsonian features predominant and MSA-A with autonomic signs and symptoms. MRI has an important role in its diagnosis with a characteristic finding described as "hot cross bun" sign seen in MSA of cerebellar type (MSA-C). We have seen two cases of MSA-C referred to Radiology Department, Civil Hospital Karachi in February 2017 and March 2017 who presented with difficulty in walking and speech and foecal and urinary incontinence. The MRI showed atrophy of pons, cerebellum and middle …

Department of Radiology
Objective: To determine the frequency and patterns of normal anatomical variation of Circle of Willis on magnetic resonance angiogram in adults without cerebrovascular disease.
Methods: This descriptive cross-sectional study was conducted at the Radiology Department of Dow University of Health Sciences / Civil Hospital, Karachi, from January to December 2016, and comprised patients referred for magnetic resonance imaging of the brain and magnetic resonance angiogram without any clinical or radiological manifestation of cerebrovascular disease, primarily including those with suspected demyelination, infection, epilepsy or metastases. Three-dimensional time-of-flight magnetic resonance angiography was performed. The Circle of Willis was assessed for its completeness …
