Redundant nerve root syndrome(RNRS) is a rare case. It was first reported by Verbiest in 1951. Thereafter a few cases were reported in neurosurgical field, but they were not reported in neurological field. We report a case of RNRS of the cauda equina. The clinical featuresl of the patient were chronic lumbago, radicular pain, leg weakness & atrophy, and intermittent neurogenic claudication. Myelography revealed characteristic serpentine filling defects in the cauda equina.

Tuberous sclerosis (TS) is a complex genetic disorder characterized by the formation of multiple hamartomas. It was first described by von Recklinghausen in 1862. In 1880, Boumeville coined the term sclerose tubererse. In 1908, Vogt emphasized the classic triad of seizures, mental retardation, and adenoma sebaceum. TS is inherited as an autosomal dominant trait with a high incidence of sporadic cases. TS might be a relatively common disease, but familial cases were not reported commonly in neurological field. We reported a familial TS in brothers with protean clinical expressivity.

Creutzfeldt-Jakob disease (CJD) is a rare dementing illness that usually affects older adults and is characterized by a rapidly progressive dementia, ataxia, and myoclonus. The disease is due to an unusual transmissible protein called a prion. The diagnosis is often suspected on the basis of electroencephalographic (EEG) and clinical findings. Our case was 62-year-old woman, who presented acute onset rapid progressive dementia, myoclonus, heightened startle reaction, extrapyramidal symptoms, and died about 2.5 months after onset of disease. We diagnosed this case as CJD with typical EEG pattern and clinical features.

We report a case of delayed rupture of an anterior communicating artery (Acom) pseudoaneurysm following mechanical thrombectomy (MT) of a distal artery occlusion using a stent retriever. An elderly patient with right hemiparesis showed left proximal internal cerebral artery and middle cerebral artery occlusions. During MT, a fragmented thrombus moved to the anterior cerebral artery (ACA). A stent retriever was deployed to the occluded ACA, and the Acom and proximal ACA segment were significantly straightened. Additionally, we attempted a blind exchange mini-pinning (BEMP) technique, but a subarachnoid hemorrhage (SAH) occurred. Bleeding was almost entirely absorbed 9 days after the procedure, but the SAH recurred at 20 days, and computed tomography angiography revealed a new pseudoaneurysm formation in the Acom. We suggest that the proposed mechanism of pseudoaneurysm formation was likely due to the dislocation and avulsion of the Acom perforators when the ipsilateral ACA was pushed and pulled during MT.

Paroxysmal hemicrania (PH) has been recently defined as an uncommon primary headache. PH is characterized by frequent attacks of severe unilateral pain associated with autonomic symptoms. The attack frequency usually ranges from 5 to 40 attacks per day. PH is characterized by its absolute responsiveness to indomethacin. However, indomethacin is not often well tolerated because of its gastric side effects. We report two patients with PH who could not tolerate indomethacin due to its severe gastric side effects but dramatically responded to rofecoxib.

A 63-year-old Korean man presented with generalized, asymptomatic, discrete papules and coalescent annular plaques for one year. Interestingly, the patient complained of conjunctival congestion, concurrently with aggravation of the skin lesion. Histopathologic findings of the skin lesion and conjunctiva revealed giant cells engulfing fragmented elastic fibers, and a diagnosis of actinic granuloma with ocular involvement was made. Ten months later, the patient revisited with a two-week history of bilateral temporal headache, neck pain, intermittent jaw claudication, and blurred vision. Biopsy of the temporal artery confirmed the clinical diagnosis of temporal arteritis. Both actinic granuloma and temporal arteritis show similar pathologic process, and this case supports the hypothesis that actinically degenerated elastic tissue is likely to be the antigenic basis of actinic granuloma of the skin and temporal arteritis.

Methotrexate(MTX) is currently one of the most important antineoplastic drugs used in chemotherapy. Intrathecal(IT) MTX is widely used to treat or prevent meningeal leukemia and lymphoma. Aseptic meningitis following IT MTX is not uncommon, but not reported frequently in neurological field. We report a case of aseptic meningitis following IT MTX in acute lymphocytic leukemia.

Acute aseptic meningitis is a rare complication of herpes zoster. It is usually regarded as a complication of the cutaneous infection in patients with impaired cellular immunity. Herpes zoster virus is a rare cause of viral meningitis. In one of three patients with herpes zoster meningitis, varicella-zoster virus DNA was detected by the polymerase chain reaction in the cerebrospinal fluid. We report three cases of acute aseptic meningitis followed by herpes zoster.

Herpes zoster is a viral disease that produces inflammatory lesions in the posterior root ganglia and is characterized clinically by pain and a skin eruption in the distribution of the affected ganglia. Involvement of motor roots or the CNS occurs in a small percentage of the patients. There are few reports about multiple cranial and upper cervical nerve involvement. We report a herpes zoster with multiple cranial(VI, VII, VIII, XII) and upper cervical(C2,3) nerves involvement. The patient was a 79-year-old woman who presented with painful vesicular eruption on left side of face and neck. She complained of decreased hearing and hyperacusis of left ear. Neurologic examination showed decreased taste sensation of left anterior tongue, left facial palsy, and tongue deviation to the left side.
