“…73 Though most SALs are found in the epidural space (as mentioned previously), there have been several reports of intradural (including intramedullary) locations. [111][112][113][114][115][116] Historically, SALs have been classified as noninfiltrating and infiltrating, 108 with the latter referring to tumoral infiltration into the vertebral body and/or adjacent soft tissues. In the present review, only 13.4% of tumors were found to be infiltrating in nature.…”

“…[15][16][17] The majority of reported spinal angiolipomas originate in the dorsal aspect of the thoracic segment and show no tendency to infiltrate the surrounding bone. According to Lin and Lin,18 angiolipomas are subdivided into two types: infiltrating and noninfiltrating. The infiltrating type is unencapsulated and contains areas in which the vascular constituent predominates.…”

Lumbar spinal angiolipomas: report of two cases and review of the literature

Study design: Case report and review of the literature. Objectives: To describe two patients with angiolipoma in the ventral aspect of the lumbar epidural space, to discuss the clinical, radiologic, and surgical features of these lesions, and to review previously reported cases. Setting: Rome, Italy. Methods: Two cases, a 60-year-old man and a 54-year-old woman presented with lumbarsciatic pain but with no abnormal neurological signs. Investigation (CT and MRI) demonstrated lumbar tumours. Results: Laminectomy and excision of the tumors were performed, and symptoms improved immediately. Conclusions: Magnetic resonance imaging with suppression fat sequences allows the recognition of these lesions. The prognosis after surgical removal of spinal angiolipoma is favorable.

-We present a case of a 46-year old woman with a ventral epidural angiolipoma at the lumbosacral level with erosion of the sacrum. About ninety cases of spinal angiolipomas have been previously described in the literature, most of them situated on the thoracic region, dorsal to the dural sac. Angiolipomas can be radically excised with a good prognosis even in the presence of bone erosion. We did not find any other angiolipoma at the sacral level surgically explored in the review of the literature. Spinal angiolipoma is a benign tumor of the epidural space. It is a rare cause of spinal cord compression, accounting for 0.14% to 1.2% of the spinal tumors 1 . It is considered a distinct clinical and pathological entity traditionally grouped as a variant of lipoma 1 . Characteristically the tumor lies over the dorsal aspect of the dura at the thoracic level 2-7 . Its port-wine color or dark brown appearance contrasts very well with the normal epidural fat 1,8,9 . Sometimes the tumor can be more aggressive and invade the contiguous bone and adjacent soft tissues 10,11 . We report a patient with a lumbosacral angiolipoma with bone erosion associated with a L4-L5 left sided disc herniation. CASEA 46-year old female with a history of ten years of low back pain had a worsening of the symptoms in the three months before diagnosis. The pain radiated down the posterior aspect of the left thigh, calf and ankle, and increased with walking and physical strength. The patient also referred a progressive numbness of the perineum. A neurological examination demonstrated a mild paresis of the plantar flexion of the left toe and hypoactive left jerk reflex. A positive straight leg-raising test at ten degree at the left side could be elicited. Superficial hypoesthesia at the lateral aspect of the left foot, buttocks and perineum was noted. An X-ray of the lumbar spine and sacrum showed erosion of the posterior aspect of the sacrum and widening of the sacral canal. A MRI scan revealed an epidural mass displacing the dural sac posteriorly, eroding the bone and projecting to the anterior sacral foramina with the sacral root. The mass was isointense in T1-weighted and hyperintense in T2-weighted and showed a homogeneous and intense enhancement with gadolinium infusion. There was also a left sided disc herniation associated with the upper limit of the tumor at the level of L4-L5 space (Fig 1).She was submitted to a L4-L5 laminectomy and a posterior opening of the sacral canal with a wide exposure of the dura and sacral roots bilaterally. The dural sac was pushed back and ventrally compressed by a firm and large port-wine highly vascularized mass, which partially encased the sacral roots and infiltrated the sacrum (Fig 2). The mass was totally resected with preservation of the roots.
