Haemorrhagic Thymic Cyst Masquerading a Thick Walled Neoplasm: A Case Report and Review of Literature

Abstract

Thymic cysts are rare anterior mediastinal cysts that are incidentally detected during routine imaging in patients or during the workup for chest pain with dyspnea. Here, we describe a rare case of a hemorrhagic thymic cyst in a 30-year-old man who presented with recurrent chest pain. Upon further evaluation using echocardiography, CT, and MRI, a well-defined, thick-walled, multiloculated cystic lesion in the anterior mediastinum was identified. The patient underwent surgery and was diagnosed with a hemorrhagic thymic cyst. Postoperatively, he was stable and discharged on the fifth day without complications. This report highlights the role of multimodality imaging in the diagnosis of thymic cysts.
