Spinal angiolipoma is a rare benign tumour. It usually presents as a slowly progressive compressive lesion. Bleeding in this tumour is extremely rare and is spontaneous and acute. This is the first reported case of post-traumatic bleeding from a spinal angiolipoma, who developed subacute progressive paraparesis. The pathological definition of this rare entity is not well established. Histologically it is distinct from cutaneous angiolipoma.

    ABSTRACT: Angiolipoma of the spine is a benign neoplasm consisting of both mature fatty tissue and abnormal vascular elements, and usually presents with a slow progressive clinical course. Our patient presented with bilateral lower extremity weakness and chest-back numbness. Physical examination revealed adipose elements superficial hypesthesia below the T5 level and analgesia below the T6 level. Magnetic resonance imaging (MRI) scan showed an avidly and heterogeneously enhancing mass which was located in the posterior epidural space. Compression of the thoracic cord by the fusiform mass was seen between T3-T4. During the operation, a flesh pink vascular mass (4.7 cm × 1.0 cm × 1.0 cm) with obscure margin and strong but pliable texture was found in the posterior epidural space extending from T3 to T4. There was no infiltration of the dura or the adjacent bony spine. Histopathological study of the surgical specimen showed a typical angiolipoma. We review the previously documented cases of spinal extradural angiolipomas performed with MRI.

    ABSTRACT: Angiolipomas are rare benign tumors, accounting for 0.14% to 1.2% of all tumors of the spinal axis with vascular and fatty histological features. Spinal angiolipoma (SAL) is most commonly found in the thoracic region and has high signal on contrast enhanced fat-saturated T1-weighted imaging. Although the international literature is extensive, there are few cases reported in United States. To present a case of SAL located in the thoracolumbar region without high signal on contrast enhanced fat-saturated T1-weighted imaging and to review previously reported cases. Case report and review the literature. Magnetic resonance imaging obtained in a 68-year-old man with a long history of lumbago showed a heterogeneous mass (T10-L1) hyperintense on T1-weighted imaging but not enhancing on suppression fat sequences, suggesting epidural hematoma. Surgical excision of the lesion was performed, and SAL was diagnosed and confirmed by pathology. The patient became asymptomatic. The predominance of either vascular or fatty components inside the tumor might alter the expected results on magnetic resonance imaging with suppression fat sequences.

    ABSTRACT: We report a 58-year-old man presenting with acute paraplegia. MRI showed a haematoma within a well-defined epidural lesion at C7-D1. Intraoperatively, organised epidural haematoma surrounded by tumour tissue was found. The final histopathology report was angiolipoma. The patient had dramatic recovery. Angiolipomas should be considered in the differential diagnosis of acute paraplegia when imaging shows well-circumscribed haematoma.
