Retroperitoneal ovarian venous hemangioma: A case report.

Retroperitoneal venous hemangioma is a rare vascular malformation. The present study reports a unique case of a 68-year-old female with a retroperitoneal ovarian venous hemangioma that was surgically resected. Computed tomography and magnetic resonance imaging showed a retroperitoneal mass anterior to the left kidney. Enhanced imaging revealed a close relationship between the mass and surrounding vessels, suggesting a retroperitoneal vascular neoplasm. Histopathological examination of the tissue after complete surgical resection confirmed the diagnosis of a retroperitoneal ovarian venous hemangioma. This case provides crucial insights for clinicians to enhance their understanding of ovarian venous hemangioma through the integration of multimodal imaging characteristics and pathological evidence, thereby contributing to the reduction of misdiagnosis in clinical practice.
