Cervical Sympathetic Chain Schwannoma in the Parapharyngeal Space: A Rare Case and Literature Review

Parapharyngeal schwannomas are rare neurogenic tumors that often present with vague symptoms, delaying diagnosis. CSC schwannomas, though uncommon, carry a high risk of postoperative complications such as FBS and Horner's syndrome. Accurate imaging, early recognition, and multidisciplinary planning are essential for safe surgical resection and optimal patient outcomes. This case, alongside our literature review, emphasizes the importance of correlating tumor origin with clinical behavior and postoperative sequelae.
