Background: A schwannoma is a benign peripheral nerve tumor. Predicting the involvement of a nerve on symptoms or magnetic resonance (MR) findings is crucial to the diagnostic process. Purpose: To compare symptoms, MR findings, and histological findings between major-nerve schwannomas and intramuscular schwannomas. Material and Methods: Thirty-four patients with 36 palpable schwannomas (29 major-nerve schwannomas and seven intramuscular schwannomas) surgically excised and proven histologically were retrospectively reviewed. Results: Frequencies of the Tinel-like sign, split-fat sign, entering and exiting nerve, and low-signal margin indicate the presence of a nerve, and were significantly higher in major-nerve schwannomas than in intramuscular schwannomas. In tumor morphological patterns (target sign, inhomogeneous and homogeneous pattern), there were no significant differences between major-nerve schwannomas and intramuscular schwannomas. Schwannomas showing the target sign histologically tended to be less degenerative. All major-nerve schwannomas and five of the intramuscular schwannomas produced some characteristic symptoms and/or MR findings, but two intramuscular schwannomas did not have any characteristic symptoms and findings. Conclusion: In major-nerve schwannomas, the Tinel-like sign, split-fat sign, entering and exiting nerve, and low-signal margin are commonly observed and useful for diagnosis. In intramuscular schwannomas, these characteristic findings are less common, which makes diagnosis difficult.

In this paper, we report a case of bilobed schwannoma, presented in the roof of orbit arising from supraorbital nerve. A 62-year male presented with a nontender mass in superior part of orbit and eccentric proptosis. Visual acuity and rest of ocular examination were normal. CT scan and MRI orbit revealed an extraconal homogenous bilobed mass, of size 3.5 to 2.5 cms in roof of orbit. Fine needle aspiration cytology was done, which was suggestive of schwannoma a peripheral nerve tumor. Successful surgical excision of intact bilobed schwannoma was done with careful separation and preservation of supraorbital nerve from which it was originated. Postoperative period was uneventful though rare, less than 1%, schwannoma can present as painless mass in the orbit and proptosis. Treatment of choice is surgical excision of intact tumor to prevent recurrence and preservation of peripheral nerve from which it arises.
