Abstract
BackgroundCavernous hemangioma of the rib is extremely rare benign vascular tumor. It is difficult to diagnose in time because both invasive and noninvasive examinations usually fail to distinguish it from other tumors of the rib and other bones.Case presentationWe described an asymptomatic 44-year-old woman with cavernous hemangioma of the rib that was incidentally discovered in the bathing. The tumor was completely resected by minithoracotomy through posterolateral incision. The pathological tissue was diagnosed as a cavernous hemangioma composed of thin-walled blood vessels and red blood cells.ConclusionsWe reported this case of giant cavernous hemangioma of the rib for its extremely rare occurrence. The preoperative diagnosis is a challenge both clinically and radiologically, and difficult to distinguish this tumor from other tumors of the rib or long bones.
Highlights
Cavernous hemangioma of the rib is extremely rare benign vascular tumor, which should be considered in the differential diagnosis of rib tumors, especially in asymptomatic patients
A definite diagnosis of cavernous hemangioma was made based on histopathology examination results of the resected mass (Fig. 3)
Hemangioma is a benign neoplasm of blood vessels that can occur throughout the body
Summary
We reported this case of cavernous hemangioma for its extremely rare occurrence in the eleventh rib, which is the false and floating rib and relatively small and delicate. Preoperative diagnosis remains a challenge both clinically and radiologically. It is still difficult to distinguish the disease from other tumors in the rib. Surgical resection provides materials for histopathologic diagnosis. We hope more cases of rib hemangiomas will be investigated and explored to find out reasons for gender and location differences of rib hemangioma
