Rapid normalization of a highly thickened pericardium by chemotherapy in a patient with T-cell acute lymphoblastic lymphoma.

The most common tumor that affects the pericardium is malign lymphoma. T-cell lymphoblastic lymphoma (TLL) is a rare type of malign lymphomas. In this manuscript, we are reporting a patient with TLL with pericardial involvement diagnosed incidentally during the evaluation of pleural effusion. Echocardiographic examination showed thickened pericardium and pericardial effusion. The pericardial thickness was found to be 13 mm by computerized tomography and confirmed by echocardiography. The patient had systemic chemotherapy for TLL. On day 30 of chemotherapy, computerized tomography of the thorax and echocardiographic examination revealed normal pericardial thickness and minimal pericardial effusion.
