Abstract Background Intramuscular hemangioma (IMH) is an uncommon type of hemangioma, and primary IMH of the intercostal muscle is even rarer. Only a few reports describe IMH of the intercostal muscle, and there are no review articles on this topic. We report our experience with a younger female patient, who underwent video-assisted thoracic surgery with tumor resection and review the previous literatures of intercostal IMH. Case presentation An asymptomatic 17-year-old woman showed a 29-mm, homogeneous, intrathoracic nodule in the left chest wall, attached to the second and third ribs on computed tomography. We performed exploratory thoracoscopic surgery and the tumor was excised without surrounding rib resection. Histopathologic examination of the surgical specimen revealed proliferation of small blood vessels within the surrounding striated muscle, leading to the diagnosis of intercostal IMH. The surgical margin was negative. The patient’s postoperative course was uneventful, and there has been no evidence of recurrence for more than 18 months after surgery. Conclusions We describe a case of intercostal IMH, who received tumor resection with clear excision margin without surrounding rib resection. Preoperative diagnosis is challenging due to its rarity, but intercostal IMH should be recalled as a differential diagnosis of chest wall tumor. Tumor excision without surrounding rib resection is acceptable for intercostal IMH, when there is a good possibility of achieving negative surgical margin.
