Antisynthetase syndrome: a case report.

The case is about a 48-year-old man with one week history of progressively worsening shortness of breath and reduced exercise tolerance. Laboratory investigations revealed raised ESR, creatine kinase (CK) and positive anti-aminoacyl-transfer RNA synthetase. High resolution computed tomography (HRCT) chest showed prominent mediastinal lymph nodes and scattered lung nodules. These findings along with clinical features and investigations confirmed the diagnosis of antisynthetase syndrome (ASS). The radiological investigations proved to be the key step in diagnosis and management of this case.
