“…Spinal angiolipomas (SAL) are rare benign tumors, accounting for about 0.14–1.2% of all spinal axis tumors and 2–3% of spinal epidural tumors [1]. They most commonly occur in mid-thoracic region, purely lumbar location is rarely reported [2, 3].…”

BackgroundSpinal angiolipomas (SAL) are rare benign tumors, commonly presenting with slow progressive spinal cord compression. There are only about 170 cases identified so far. Magnetic resonance imaging (MRI) has become the modality of choice for SAL. The purpose of this article is to report three cases of SAL and their characteristic MRI features.Case presentationThree cases of epidual spinal angiolipoma from ethnic Han Chinese patients are presented here, including one lumbar and two thoracic tumors. MRI imaging findings were reviewed.ConclusionsMultiple MRI technology for characterization of SAL provides useful information for differential diagnosis and therapeutic management.

“…They did not regard angiolipomas as protean, and the signals of angiolipomas in the MRI examination were basically the same. MRI typically shows an iso- to hyperintense mass on T1-weighted images and hyperintense without flow voids on T2-weighted images, while the variable vascular and adipose elements of the tumor often shows significant heterogeneity in the MRI studies [ 2 , 11 ]. In our case, in sagittal T1-weighted images, the tumor's signal was inhomogeneous with an isointense signal present in the center part and a high signal present in the upper part.…”

“…Spinal angiolipomas that generally induce slow progressive cord compression are most commonly found in the thoracic region and have a high signal in contrast-enhanced fat-saturated T1-weighted imaging. However, the predominance of either vascular or fatty components inside this tumor could alter the expected results on magnetic resonance imaging (MRI) with fat-suppression sequences [ 2 ].…”

Angiolipomas are relatively rare benign tumors. Spinal angiolipomas that generally induce slow progressive cord compression are most commonly found in the thoracic region. A 49-year-old female with obesity presented with a 1-week history of progressively worsening back pain, paresthesia of lower limbs, and gait disturbance. When thoracic magnetic resonance imaging (MRI) revealed a dorsal epidural mass at the Th5–Th8 level, the patient underwent a laminectomy for gross total excision of the lesion. Both mature fatty tissue and abnormal proliferating vascular elements with thin or expanded walls were observed in the resected tumor. Nonfiltrating spinal angiolipoma was diagnosed and confirmed by pathology. After the operation, sensory loss, numbness, and gait disturbance were improved following the disappearing severe back pain. Following examinations indicated the absence of recurrence within 1 year. The angiolipomas of the spine are rare causes of spinal cord compression that generally induce slow progressive cord compression, but sudden onset or rapid worsening of neurological deterioration is observed in hemorrhagic spinal angiolipoma.

“…A female predominance has been observed. [13,14] The most common location of spinal angiolipoma is the thoracic epidural space. Thoracic predominance of the tumor could be the result of the regional variation in the blood supply in the spine, wherein the mid-thoracic spine is the least perfused.…”

“…The ratio of fat to vessels is variable, ranging from 1:3 to 2:3. [14] Immunohistochemical assays were performed in a few cases, and a low proliferation rate was found with Ki-67. Samdami et al observed a positive stain for CD31, Factor XIIIa, and Factor VIII and a negative stain for gliofibrillar acid protein.…”
