Sarcoidosis is a multisystemic granulomatous disease of unknown origin occurring worldwide and affecting people of all races and ages. This disease manifests most frequently with bilateral hilar lymphadenopathy, pulmonary infiltrates, and skin and ocular lesions. ⋯ Splenomegaly is usually homogeneous, but multiple low-attenuating nodular lesions are occasionally seen and easily mistaken for lymphoma, metastases, or infections such as tuberculosis. We describe an unusual case of sarcoidosis in a woman who presented with massive splenomegaly with extensive nodularity that cleared completely with corticosteroid therapy.

Cardiovascular disease (CVD) is the leading cause of death in the United States. In comparison to whites, African-Americans have a higher risk of dying from CVD and have a worse risk factor profile. The Jackson Heart Study (JHS) is designed to investigate the origin and natural history of CVD in African-Americans. ⋯ This article describes the roles of specialized research agencies contributing to JHS, and the methodologies being utilized to accumulate study data. A diverse collection of scientific disciplines is required to collect the information needed to meet the objectives of the JHS.
