Hughes-Stovin Syndrome: A Rare Cause of Thrombosis and Pulmonary Artery Aneurysm.

Abstract

Hughes-Stovin Syndrome (HSS) is a rare clinical condition characterized by thrombophlebitis as well as multiple pulmonary and bronchial aneurysms. It commonly presents with coughing, dyspnea, fever, chest pain, and hemoptysis, and its management usually consists of surgical and medical approaches. In thisreport, we discuss a case of a patient with HSS. A 30-year-old male patient was admitted to the pulmonary medicine ward for hemoptysis. After evaluation with chest CT, bilateral pulmonary embolism and pulmonary aneurysms were observed. Due to a history of aphthous lesions, Behçet's disease (BD) was considered the initial diagnosis; however, the patient did not fit the criteria and was later diagnosed with HSS. Intravenous methylprednisolone was initiated, along with a maintenance treatment with cyclophosphamide. Treatment response was observed in the fourth month; however, due to the persistence of hemoptysis, additional cycles of cyclophosphamide were later required, under which the patient's condition has been stable. HSS currently lacks clear diagnostic criteria, and further studies are needed to investigate genetic backgrounds, familial transmissions, and treatment alternatives.
