ABSTRACT
Left ventricular apical ballooning is an increasingly reported phenomenon with an onset that is usually triggered by severe and often acute emotional incidents. We report a rare case of acute left ventricular apical ballooning syndrome, mimicking acute ST-elevation myocardial infarction, in a post menopausal woman whose only predisposing factor was an all-night cocaine binge.

Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative disease of the synovial membrane of joints, tendon sheaths, and bursas. Joint aspiration typically yields hemorrhagic or xanthochromic/serosanguinous (brown, murky) fluid. We describe a case of PVNS that presented as an acute, painless, nontraumatic right knee effusion with clear synovial fluid on arthrocentesis. Initial magnetic resonance imaging of the knee revealed no evidence for hemosiderin. A diagnostic arthroscopy and surgical arthrotomy revealed a unique case of PVNS evolving from local to diffuse involvement of the synovium.
