A case of diaphragmatic hemangioma completely resected by partial diaphragmatic resection

Abstract

Abstract Diaphragmatic hemangiomas are rare tumors and the preferred resection range in surgical procedures is considered on a case-by-case basis. We report a case of diaphragmatic hemangioma that was completely resected by partial diaphragmatic resection. An 81-year-old man was referred for the examination of right diaphragmatic mass. Computed tomography revealed two contrast-enhanced nodules (diameter: 17 and 10 mm, respectively) on the right diaphragm. The nodules were completely resected by partial resection of the diaphragm via video-assisted thoracic surgery using an ultrasonic coagulation and incision device. Resection was performed leaving part of the muscular layer of the diaphragm. Histopathology confirmed the nodule to be hemangioma originating from the diaphragm and no hemangiomatous lesions were noted in the normal connective tissue in the resected stump. Partial diaphragmatic resection is a less invasive treatment method and may be a useful surgical procedure for diaphragmatic hemangioma.
