Hemorrhagic Sudden Onset of Spinal Epidural Angiolipoma

الملخص EN

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.
