Why the study?
Masson's tumors in the heart are exceedingly rare, particularly in the left ventricle, and mimic other cardiac tumors such as myxomas.
Cardiac Masson's tumor is an exceedingly rare benign tumor that can present in the left ventricle and mimic myxoma on imaging, requiring surgical excision for definitive diagnosis and treatment.
Masson's tumor can occur in the LV; extends sparse cardiac reports but leaves management questions open.
Masson's tumor is a benign tumor that usually arises secondary to vascular trauma or thrombi, leading to vascular proliferation. Masson's tumors are most commonly reported in the head, neck, and extremities. Cases in the heart are exceedingly rare, with most case reports describing the left atrium as the most common location. Even though the tumor is benign, excision is recommended due to the risk of embolization. This is a case of Masson's tumor located in the left ventricle. The patient is a 24-year-old female, who presented complaining of palpitations and lightheadedness. Transthoracic echocardiography showed a mobile echodensity in the left ventricle. Cardiac MRI showed characteristics similar to a myxoma. The patient underwent surgical resection and a biopsy showed Masson's tumor. This case report focuses on the histopathological features and imaging findings of Masson's tumor.
