Incidental intrathorcic schwannoma post upper respiratory tract infection associated with Horner's syndrome: A case report.

Background: Schwannomas may remain asymptomatic, and may be discovered incidentally.

Case Presentation: Here we describe a case of a young female complaining of upper respiratory tract symptoms who was incidentally found to have an intrathoracic neurogenic tumor consistent with schwannoma associated with Horner's syndrome. Biopsy of the tumor revealed S100, BCL-2 and CD 99+ compatible with schwannoma. Patient had brachial plexus exploration and dissection of thoracic inlet tumor resected through video assisted thoracoscopic surgery (VATS). Patient did exceptionally well afterwards with no documented Horner's symptoms.

Conclusion: Characterized as a rare case, this patient presented post viral infection and found to have a rare tumor. Successful surgical treatment alleviated her symptoms.
