Pheochromocytoma may cause anatomic and functional cardiac abnormalities. Various echocardiographic abnormalities have been observed, including systolic anterior movement, global hypokinesis as well as hypokinesis of the base and the apex of LV. There are no previous reports of serial echocardiographic finding in patients with pheochromocytoma. We experienced a 38-year-old woman with pheochromocytoma who suffered from acute myocardial injury. Echocardiography revealed that the acute myocardial injury started in the base in the early phase and subsequently extended to the mid-portion of left ventricule. The injury persisted longer in the base than the mid-portion. than 1.5 times the adjacent normal coronary artery.

Granulocytopenia, which can be seen in patients with Graves' disease during treatment with antithyroid agents, could be a self resolving transient episode or can imply the beginning of life threatening agranulocytosis requiring a change in treatment modality. Transient granulocytopenia could be a manifestation of hyperthyroidism itself, or a mild side effect of antithyroid drugs. Aganulocytosis is a rare, but major complications of the termination drug, propylthiouracil (PTU), requiring prompt termination of the medication, and intensive care. Therefore, differentiation of agranulocytosis and transient granulocytopenia, is important, but is not practically easy. We introduce a case of transient granulocytopenia, which was detected in a patient with Graves'Disease, accompanied by underlying type 1 diabetes mellitus, during treatment with PTU. Diagnosis of transient granulocytopenia was made by a normal granulocyte count following a single injection of G-SCF, and the patient was treated with conservative therapy. This case confirms a diagnostic tool for differentiating transient granulocytopenia and PTU-induced agranulocytosis.
