Banushree"],"abstract":"Background: Pure spinal epidural cavernous angiomas (PSECA) are rare lesions that typically present with myelopathy symptoms. This case report discusses a thrombosed primary cavernous haemangioma located in the thoracic extradural space of a 16-year-old girl who exhibited only mild intermittent paresthesia in the lower limb. Methods: The patient underwent MRI imaging, which revealed a spindle-shaped lesion in the posterior aspect of the spinal canal at the T7-T9 level, and a T7-T9 laminectomy was performed for surgical intervention. Intra-operative findings included a reddish-brown, soft lesion with cystic spaces, which was excised in one piece. Results: Histopathological analysis confirmed the diagnosis of thrombosed cavernous haemangioma, characterized by cavernous spaces lined with thin endothelium and filled with organized blood clots. The patient did not exhibit any preoperative neurological deficits, which was atypical given the size of the lesion. Conclusion: This case highlights the unusual presentation of a sizeable thoracic cavernous haemangioma with minimal symptoms, suggesting that thrombosis may reduce the compressive effects on the spinal cord. Such lesions should be considered in the differential diagnosis of asymptomatic extradural lesions in young patients.
