The authors present the MR appearance of an intracanalicular eighth nerve lipoma in a 30-year-old woman, describe the clinical manifestations, and discuss the possible etiology; biopsy findings were conclusive. Precontrast T1-weighted images should be obtained.

Clewett Price, D. M., and Trounce, D. Q. (1973). Archives of Disease in Childhood, 48, 881. Cyclic oculomotor paralysis. Cyclic oculomotor palsy is a rare condition that is usually either congenital or presents in early childhood. Its essential features consist of paralysis of the oculomotor nerve supplying one eye with cycles of involuntary spasm and relaxation of the sphincter pupillae, and u...

Ophthalmopathy related to thyroid disease is due mainly to diffuse periorbital or eye muscle inflammation. It is more common in Grave’s hyperthyroidism and rare in Hashimoto’s hypothyroidism. Here we report a case of recurrent oculomotor nerve palsy associated with autoimmune hypothyroidism. Brain MRI revealed enhancement of the oculomotor nerves. Despite thyroid hormone replacement therapy, oc...

Benign recurrent sixth nerve palsy in children is rare. It typically occurs following viral illness or immunization, and prognosis is usually excellent. However, it is always a diagnosis of exclusion given the more serious alternative causes. Therefore, a thorough examination with brain imaging is recommended. The authors report a child with six recurrent episodes of isolated benign sixth nerve...

PURPOSE To compare the MR characteristics of the oculomotor nucleus with its appearance on anatomic images. METHODS Specimens of cadaveric brains were imaged in a 3.0-T MR imager equipped with a 3.0-cm solenoid coil. The specimens were sectioned, stained, and examined histologically. On anatomic sections, the oculomotor nuclei, medial longitudinal fasciculus, red nuclei, and oculomotor nerve ...

We describe a case of acute oculomotor nerve palsy caused by a ruptured middle cerebral artery (MCA) aneurysm. A 59-year-old female presenting with headache and nausea was admitted to our hospital. Her consciousness was alert, and had no other neurological deficit without left oculomotor nerve palsy. A computed tomography (CT) showed SAH extending from left sylvian cistern to basal cistern. CT ...

Prion diseases, also known as the transmissible spongiform encephalopathies (TSEs), are a group of slowly developing neurodegenerations occurring in human and animals. Prion diseases can be transferred between animals, humans, from humans to animals, and from animals to humans. As a result, the central nervous system is attacked, resulting in microglia activation, astrocytosis, prion plaque dep...

BACKGROUND Aberrant regeneration of the third cranial nerve is most commonly due to its damage by trauma. CASE A ten-month old child presented with the history of a fall from a four-storey building. She developed traumatic third nerve palsy and eventually the clinical features of aberrant regeneration of the third cranial nerve. The adduction of the eye improved over time. She was advised for...

Isolated third cranial nerve palsies in head trauma patients can be the result of direct or indirect damage to the oculomotor nerve. They are usually associated with severe head trauma. We reported a case of isolated oculomotor nerve palsy associated with minor head injury. No initial loss of consciousness was recalled. Computed tomography (CT), magnetic resonance imaging (MRI), and magnetic re...

An online PubMed database search was conducted using the following algorithm: ('papaverine'[All Fields] OR 'papaverine'[MeSH Terms] 'papaverine'[All Fields]) AND ('intracisternal'[All Fields]. Only articles that attributed oculomotor nerve palsy solely to intracisternal Papaverine were further analysed.
