A 40-year-old female presented with back pain without any neurological deficits. Radiological investigations revealed a ventrally situated paraspinal lesion causing widening of the right D4 neural foramen. She underwent a right posterolateral thoracotomy and excision of the lesion in toto, which was reported as a hydatid cyst on histology. Ventrally situated paraspinal extradural hydatid cysts are rare. A Transthoracic surgical exposure offers a direct approach for complete excision of the lesion, minimizing the chances of rupture and spillage.
