BACKGROUND AND PURPOSE Complete ophthalmoplegia, the combination of bilateral ptosis with loss of all extraocular movements, is rarely a consequence of ischemic stroke. We describe 3 patients who had complete ophthalmoplegia as a manifestation of bilateral paramedian midbrain-thalamic infarction, and we discuss possible pathophysiologic mechanisms. Summary of Cases- Three patients presented wit...

M. Tariq Bhatti, MD SECTION 1 A 64-year-old man was referred for evaluation of double vision in March 2009. Four months prior, he experienced daily pain in the region of the right forehead and right eye. Two months later, he noticed constant binocular, vertical double vision. Evaluation by an outside ophthalmologist resulted in the diagnosis of a right 4th cranial nerve (CN) palsy, a normal cra...

Parathyroid carcinoma is an uncommon malignancy. Of the fewer than 400 cases reported, most have been cases of producing parathyroid carcinoma with accompanying hypercalcemia. Only 13 patients with nonproducing parathyroid carcinoma have been described. Nine of these 13 patients had metastatic disease. We report a patient with i.c. metastasis. Distal metastases of producing parathyroid carcinom...

Objective: Describe and discuss a typical case with recurrent painful ophthalmoplegic neuropathy (RPON), demonstrate likely extrinsic compression of the sixth cranial nerve by vascular loop. Background: RPON is rare, but well-known entity, characterized attacks ophthalmoplegia associated ipsilateral headache. The etiology unknown, neurovascular conflict (NVC) has been suggested as cause. Method...

Primary hepatocellular carcinoma is one of the most common cancers in Taiwan, but orbital metastases are rare. To the best of our knowledge, only 10 cases of metastases to the orbit have been described in the literature. This may be related to the short clinical course of the malignancy and the fact that most patients died before metastasis occurred. We describe a 69-year-old man who developed ...

BACKGROUND/AIM Serum antibody against ganglioside GQ1b is reported to be closely associated with immune mediated ophthalmoplegia in the Fisher and Guillain-Barré syndromes. Its presence against glycolipids, in particular ganglioside GQ1b, was investigated in patients with ophthalmoplegia of unknown origin. METHODS 16 patients with ophthalmoplegia, the cause of which could not be confirmed fro...

Internuclear ophthalmoplegia is a remarkable finding, particularly in patients victims of head injury. The medial longitudinal fasciculus, which is believed to be lesioned in cases of internuclear ophthalmoplegia, has an unique brain stem position and the mechanism involved in brain stem contusions implies a maximal intensity of shearing forces on the skull base. We describe a very rare associa...
