An 80-year-old man was transferred to our institution with lower limb edema and worsening dyspnea following the administration of diuretic medication. Transthoracic echocardiography and computed tomography revealed a giant hepatic cyst (176×190 mm) compressing his right atrium and inferior vena cava (IVC). ⋯ The procedure was uneventful, and he was discharged without any complications on postoperative day 9; he had no recurrent symptoms or hepatic cysts at the postoperative 2-month follow-up. Therefore, a giant hepatic cyst can cause IVC syndrome, and laparoscopic deroofing is a beneficial approach for the treatment of accessible cysts.

Case Reports
A Case of Diffuse Alveolar Hemorrhage Associated with Dilated Cardiomyopathy and Sleep Apnea Syndrome.
We herein report a case of diffuse alveolar hemorrhage (DAH) associated with dilated cardiomyopathy (DCM) and sleep apnea syndrome (SAS) in a 47-year-old man. The patient exhibited recurring dyspnea and bloody sputum. Chest radiography showed bilateral diffuse infiltrative opacities without pleural effusion. ⋯ Laboratory and pathological findings ruled out the possibility of collagen diseases and vasculitis. Overnight polysomnography revealed concomitant severe obstructive SAS. Treatment with continuous positive-pressure ventilation and pharmacological therapy for DCM prevented recurrence of DAH.
