Spinal angiolipomas are rare lesions usually found in the epidural space of the thoracic spine. The infiltrating type of spinal angiolipomas is extremely rare. This report presents the case and reviews the related literature. A 58-year-old man was presented with a 7-month history of progressive weakness and sensory change of lower extremities. Magnetic resonance images showed a well-enhanced mass infiltrating the vertebral foramen at the T4-5 level. Resection of the tumor was performed. Histological study revealed the tumor as an angiolipoma. The patient was relieved from symptoms after tumor resection.

Angiolipomas in the lumbar spinal region are extremely rare. The present report describes the identification of such a tumor and its removal, and discusses the tumor characteristics and prognosis. A 74-year-old woman was presented with a 5-month history of lower back pain. Severe radiculopathy was experienced in the left leg for 5 days prior to the presentation, and there were no neurological deficits. Magnetic resonance (MR) images showed an approximately 3.5 cm heterogeneously enhanced and elongated mass at the left L5-S1 level. A portion of the mass appeared with high signal intensity on T2-weighted MR images, with low signal intensity on T1-weighted images, and with high signal intensity on T1 fat suppression enhancement images. Resection of the tumor was approached via an L5 and S1 laminectomy. A fibrous sticky yellowish hypervascular tumor was identified. Histological study revealed the tumor as an angiolipoma. Symptoms were relieved after tumor excision, and there were no neurological sequelae. Although extremely rare, lumbar epidural angiolipoma should be considered in the differential diagnosis of lumbar spinal epidural lesions. The prognosis after surgical management of this lesion is favorable.

Angiolipoma is a rare benign soft tissue tumor, an unusual variant of lipoma, consisting of fatty and vascular components and located in the subcutis, usually in the trunk and extremities. We report a case of posterior mediastinal angiolipoma extending into the spinal canal and showing both fat and angiomatous features on CT scan.

Crowth of an angiolipoma of the central nervous system is rare. Only about 60 cases were searched in the literature. We report one case of spinal angiolipoma recently treated in our institution. A 67-year-old man was admitted because of burning sensation on the both lower extremities and paraparesis. He felt burning sensation on the both great toes and it progressively involved to thighs and inguinal area during the past 1 year which gradually worsened. MR image showed a spinal mass lesion at the level of T4 to T6. The lesion was isodense and hyperdense in periphery on T1-weighted image and hyperintense on T2-weighted image. The tumor was located on the posterior area of the spinal cord and markedly enhanced after intravenous Gd-DTPA. At the operation, a soft, dark-red mass was totally removed. On histological examination, the tumor was shown to be mainly composed of mature fatty cells and numerous blood vessels with enlarged lumens. Postoperative course was uneventful and the symptoms improved gradually.

Objective : Angiolipomas are usually found in the subcutaneous tissue of the trunk and limbs. Spinal angiolipomas (SALs) are uncommon and have rarely been reported. We report a series of nine SALs patients who received surgical treatment in our department. To summarize the clinical characteristics of SALs, propose our surgical strategies, and evaluate the effects of the operation. Methods : This was a retrospective review of nine SALs patients who received surgical treatment from August 2015 to March 2020. Total or subtotal resection was determined by the axial localization (dorsal or ventral) and the extent of intervertebral foramen involvement. The outcomes were assessed based on the modified Japanese Orthopaedic Association (mJOA) scoring system utilized before surgery and at various follow-up points. Results : Among the nine patients, the mean mJOA score before surgery was 6.6±2.3, compared with 10.1±1.1 at the last follow-up time point (33.4±11.8 months). All patients achieved good outcomes, even in cases of subtotal resection. Conclusion : Early surgical resection of SALs is recommended, and the specific procedures should be determined by the axial localization (dorsal or ventral) and the extent of intervertebral foramen involvement. Most of the patients had a good prognosis, even in cases of subtotal resection.
