Diagnostic Dilemma: Intracanal Schwannoma of Inferior Alveolar Nerve: A Rare Case Presentation

An intraosseous schwannoma is an infrequent benign tumour originating from Schwann cells. It can present at any age, but is more prevalent in the 2nd-3rd decade of life. They can be seen as large single unilocular or multilocular radiolucency resembling other intraosseous benign lesions of the jaw. This case report presents an intraosseous schwannoma in the posterior mandibular region of 34 years aged male patient with the chief complaint of paraesthesia and radiographic presentation with fusiform expansion of inferior alveolar nerve canal. The tumour was managed by complete excision and curettage along with resection of entrapped inferior alveolar nerve fibre, leaving most of nerve bundle unblemished. Patient was followed up regularly for any signs of recurrence and resolution of paraesthesia.
