Localized orbital neurofibromas.
Of nine patients (five men and four women, 25 to 55 years old) with localized orbital neurofibromas, only one had other systemic findings consistent with neurofibromatosis. The neurofibromas originated from sensory nerves of the orbit, producing gradual proptosis with expansion of the orbital walls in most cases. Mild orbital discomfort occurred in some patients. Preoperative and postoperative anesthesia in the distribution of the involved sensory nerves was also encountered. Five patients had multiple tumors within the same orbit. Four patients had tumors or a pedicle of the tumor extending into the superior orbital fissure. Two patients were initially thought to have fibrotic pseudotumors. Surgical excision is the treatment of choice for these tumors.
