초록
A hemangioma of the parapharyngeal space (PPS) is an extremely rare tumor and is responsible for 0.5-1% of all tumors occurring in the PPS. We report a case of PPS venous hemangioma in a 49-year-old woman presenting with diffuse swelling in the submandibular region. A preoperative computed tomography (CT) scan showed a cystic mass with multiple calcifications in the PPS. The calcific nodules were round and about 2 mm in diameter. The hemangioma was completely resected via a transcervical approach. During surgery, we found several calcific nodules, which represented phleoboliths or areas of thrombosis with dystrophic calcification. Despite its rarity, a venous hemangioma of the PPS should be considered in a differential diagnosis when a cystic mass with calcification is found by CT scan. To our knowledge, this is the first reported case of a PPS venous hemangioma; we describe its pathognomonic findings on imaging.
Abstract
A hemangioma of the parapharyngeal space (PPS) is an extremely rare tumor and is responsible for 0.5-1% of all tumors occurring in the PPS.

A preoperative computed tomography (CT) scan showed a cystic mass with multiple calcifications in the PPS. The calcific nodules were round and about 2 mm in diameter. The hemangioma was completely resected via a transcervical approach. During surgery, we found several calcific nodules, which represented phleoboliths or areas of thrombosis with dystrophic calcification. Despite its rarity, a venous hemangioma of the PPS should be considered in a differential diagnosis when a cystic mass with calcification is found by CT scan. To our knowledge, this is the first reported case of a PPS venous hemangioma; we describe its pathognomonic findings on imaging.
