BACKGROUND Herpes zoster ophthalmicus (HZO) can involve the oculomotor nerve; however, isolated trochlear nerve palsy has rarely been reported. CASE REPORT An 83-year-old man who suffered from HZO in the right frontal area and scalp subsequently developed vertical diplopia and severe pain. Cerebrospinal fluid examination and brain MRI revealed no abnormalities. Isolated right trochlear nerve ...

Eye movements in vertebrates are controlled by six extraocular muscles innervated by three of the cranial nerves – the oculomotor, trochlear and abducens. Incorrect development of this wiring network can lead to eye movement disorders, such as the congenital condition Duane retraction syndrome (DRS), which results in squint (strabismus). In DRS patients, the abducens nerve is often absent, and ...

Introduction: Oculomotor nerve palsy is an pathological condition caused by microvascular injury, head compression due to neoplasm or aneurysm, and also oculomotor can be autoimmune prosses. Peripheral neuropathy one of the clinical manifestations in patient with SLE, type cranial seen SLE patient. Patient have a higher risk serebrovascular event than general population. Case Illustration: Fema...

BACKGROUND Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. CASE PRESENTATION A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed complete left oculomotor nerve palsy. Ma...

Dear Editor, We read with great interest the review article in Cephalalgia entitled ‘Ophthalmoplegic migraine: From questions to answers’ by Ambrosetto et al. (1). The authors pointed out that, in adult-onset recurrent painful ophthalmoplegic neuropathy (RPON, code 13.9 of ICHD-3 beta), the magnetic resonance imaging (MRI) finding shows no gadolinium enhancement or nerve thickening. We experien...

We describe the case of a male patient who presented with anisocoria, and was initially diagnosed with an acute Adie's tonic pupil. On subsequent laboratory testing, he was found to have neurosyphilis. Magnetic resonance imaging demonstrated enhancement of the right oculomotor nerve. This case underscores the importance of considering this diagnosis in patients with acute onset internal ophthal...

Ahmet Çolak, Dr., MD. Department of Neurosurgery, GATA Haydarpaþa Research and Training Hospital, [email protected] Abstract Isolated oculomotor palsy due to vascular compression at the root exit zone is an extremely rare entity. A 59-year-old male patient was presented with complaints of diplopia and mild ptosis. A thin-sliced MRI demonstrated that, the right posterior cerebral arter...

We report a rare case of oculomotor nerve palsy and choroidal tuberculous granuloma associated with tuberculous meningoencephalitis. A 15-year-old male visited our hospital for an acute drop of the left eyelid and diplopia. He has been on anti-tuberculous drugs (isoniazid, rifampin) for 1 year for his tuberculous encephalitis. A neurological examination revealed a conscious clear patient with i...

A 48-year-old woman experienced sudden onset of severe headache. Computed tomography showed subarachnoid hemorrhage (SAH) and intracerebral hematoma in the right frontal lobe. Digital subtraction angiography revealed three aneurysms in the anterior communicating artery (AcomA), the right posterior communicating artery (PcomA), and the right middle cerebral artery. The AcomA aneurysm was treated...
