Lymphomatoid granulomatosis presenting as an isolated unilateral optic neuropathy. A clinicopathologic report.
A 41-year-old woman presented with a unilateral optic neuropathy that progressed to no light perception 7 weeks later. The patient was hospitalized for progressive dyspnea; respiratory failure ensued and the patient died 10 days after admission. Antemortem pulmonary biopsies and the results of necropsy revealed lymphomatoid granulomatosis with extensive involvement of the lungs and left optic nerve. This is the first case report of lymphomatoid granulomatosis presenting as a unilateral optic neuropathy.

Two patients with biopsy-proven giant cell arteritis experienced bilateral transient vision loss after bending over and after getting up from a supine position. One patient had no demonstrable signs of carotid, ophthalmic, or anterior ciliary vascular disease, suggesting that his episodes of transient vision loss were due to vertebrobasilar insufficiency. ⋯ Bilateral transient postural vision loss is an uncommon manifestation of giant cell arteritis that could reflect either severe bilateral vascular compromise of the anterior circulation or severe vertebrobasilar insufficiency. In either situation, prompt evaluation and treatment is indicated to prevent the irreversible sequelae of the disease.
