Osseous and central nervous system sarcoidosis: scintigraphic and radiographic findings.

We present a case of painful osseous sarcoid involving the tibiae bilaterally. Lesions were initially found on plain radiographs and on a 99mTc-MDP bone scan. The patient was also found to have CNS involvement of sarcoidosis in the form of diabetes insipidus and panhypopituitarism. CNS lesions were demonstrated on CT and MR images.

Subacute bacterial endocarditis with polyarthritis mimicking thrombotic thrombocytopenic purpura: a case report.

Thrombotic thrombocytopenic purpura (TTP) is a serious multisystem disorder that is usually rapidly progressive and often fatal if not diagnosed or treated. Unfortunately, the clinical and laboratory features of TTP are not specific and can also be seen in both autoimmune and infectious diseases. We describe a case where the rapid institution of therapy for a TTP-like syndrome masked a culture-negative infectious endocarditis. The diagnosis of this unique patient was established at valvulotomy, necessitated by acute aortic insufficiency.
