“…The occurrence of symptoms may be due to poor vascular drainage, which may lead to engorgement, enlargement or degeneration of the blood vessels. The occurrence of steal phenomenon, venous thrombosis, and hemorrhage can contribute to the development or sudden worsening of the symptoms [17,19,20]. Only a few cases have been reported in which hemorrhagic transformation of angiolipoma was accompanied by the sudden exacerbation of the neurological symptoms.…”

Spinal angiolipoma is composed of adipocyte and abnormal vascular elements [1]. It has an incidence of 0.04% to 1.2% among all spinal axis tumors and 2% to 3% among extradural spinal tumors [2]. Most spinal angiolipoma are expressed at the thoracic level and are associated with signs of cord compression as they enlarge slowly, therefore, a sudden deterioration in symptoms does not occur. However, hemorrhagic transformation of angiolipoma, although rare, may cause sudden worsening of neurological symptoms [3][4][5]. Unfortunately, it is difficult to differentiate these cases from simple hematoma. Herein, we report a case of hemorrhagic transformation of angiolipoma, in which we used dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for the preoperative discrimination between the tumor and hematoma, and our surgical experience.Spinal epidural angiolipoma is an uncommon benign tumor composed of vascular and fat elements. Hemorrhagic transformation of angiolipoma is very rare, and only a few cases have been reported. Herein, we report a very rare case of the surgical removal of an angiolipoma that had undergone hemorrhagic transformation. On preoperative radiological studies, it was difficult to differentiate between a simple hematoma and a mass. Dynamic contrast-enhanced magnetic resonance imaging confirmed the presence of a hypervascular mass and total en bloc removal was planned. The patient underwent T3-5 laminectomy and tumor removal surgery, and his symptoms gradually improved.
