1/108. Cervicomedullary astrocytoma simulating a neuromuscular disorder.

    A 12-year-old male developed progressive proximal upper extremity weakness over a 3- to 4-year period. The clinical findings of proximal upper extremity weakness and atrophy, prominent scapular winging, and no sensory deficits or upper motor neuron signs suggested a neuromuscular disorder. electromyography was consistent with a chronic denervating disorder involving the upper cervical anterior horn cells or their axons. A cervical magnetic resonance image revealed a large intramedullary mass extending from the inferior aspect of the fourth ventricle down to the level of T2. A biopsy of the lesion was consistent with a low-grade astrocytoma.

2/108. Spinal arachnoid cyst with weakness in the limbs and abdominal pain.

    A 7-year-old male admitted with neck rigidity, severe pain in the abdomen, and progressive weakness in the lower limbs was diagnosed as having a spinal intramedullary arachnoid cyst. There was a dramatic and immediate recovery after fenestration of the cyst.

3/108. An uncommon mechanism of brachial plexus injury. A case report.

    PURPOSE: To report a case of brachial plexus injury occurring on the contralateral side in a patient undergoing surgery for acoustic neuroma through translabrynthine approach. CLINICAL FEATURES: A 51-yr-old woman underwent surgery for acoustic neuroma through translabrynthine approach in the left retroauricular area. She had a short neck with a BMI of 32. Under anesthesia, she was placed in supine position with Sugita pins for head fixation. The head was turned 45 degrees to the right side and the neck was slightly flexed for access to the left retroauricular area, with both arms tucked by the side of the body. Postoperatively, she developed weakness in the right upper extremity comparable with palsy of the upper trunk of the brachial plexus. hematoma at the right internal jugular vein cannulation site was ruled out by CAT scan and MRI. The only remarkable finding was considerable swelling of the right sternocleidomastoid and scalene muscle group, with some retropharyngeal edema. An EMG confirmed neuropraxia of the upper trunk of brachial plexus. She made a complete recovery of sensory and motor power in the affected limb over the next three months with conservative treatment and physiotherapy. CONCLUSIONS: brachial plexus injury is still seen during anesthesia despite the awareness about its etiology. Malpositioning of the neck during prolonged surgery could lead to compression of scalene muscles and venous drainage impedance. The resultant swelling in the structures surrounding the brachial plexus may result in a severe compression.

4/108. Autosomal dominant distal myopathy not linked to the known distal myopathy loci.

    The distal myopathies are clinically, pathologically and genetically heterogenous. Thus far, seven types of distal myopathy have been linked to four chromosome loci. We recently examined four affected members from three generations of an autosomal dominant distal myopathy kindred. A muscle biopsy was performed on the index case. Muscle histopathology showed non-specific myopathic findings including increased variation in fiber size and increased internalized nuclei. No abnormal inclusions or vacuoles were present. Microsatellite markers for the four distal myopathy loci on chromosomes 2, 9 and 14 were studied on affected and several unaffected family members. Affected patients developed distal weakness in anterior foreleg muscles followed by progressive distal upper and proximal lower extremity involvement. Chromosome 2, 9 and 14 regional markers were informative and demonstrated recombinations with affected individuals in the pedigree. The resulting LOD scores obtained from the multipoint analyses gave no evidence of positive linkage to any of the regions and positively excluded (lod score less than -2) all, or virtually all, of the candidate regions examined. This autosomal dominant distal myopathy family does not show evidence of linkage to any of the known distal myopathy loci, suggesting the existence of at least one more distal myopathy locus. Furthermore, the clinical and pathological features appear distinct from other previously described but genetically-undetermined autosomal dominant distal myopathies.

5/108. hypereosinophilic syndrome: progression of peripheral neuropathy despite controlled eosinophil levels.

    Idiopathic hypereosinophilic syndrome (HES) is a disorder of the hematopoietic system, characterized by persistent elevation in the total eosinophil count (> 1500/microliter) for over 6 months, associated with organ damage and no detectable underlying cause. Treatment is centered on the reduction of total circulating eosinophils, which generally leads to remission of symptoms. We report a 68-year-old female patient with HES and peripheral neuropathy, presenting with cutaneous lesions, mental changes, cardiac and pulmonary symptoms, followed by right foot drop and eventually paraparesis, which caused an inability to ambulate. Weakness progressed to include the upper extremities despite adequate control of eosinophilia by steroids. Worsening of the peripheral neuropathy can occur despite lowering of the eosinophil levels.

6/108. Ipsilateral facial weakness in upper medullary infarction-supranuclear or infranuclear origin?

    We describe two patients with upper medullary infarctions showing ipsilateral facial weakness and relative sparing of the upper facial muscles. Electrophysiological follow-up using transcranial magnetic stimulation of the motor cortex in combination with stimulation of the peripheral facial nerve disclosed a supranuclear (corticofacial) tract lesion in one patient and a partial nuclear/infranuclear intra-axial facial nerve lesion in another.

7/108. Characteristic form of standing up from squatting in Miyoshi's distal muscular dystrophy.

    A 27-year-old woman with Miyoshi's distal muscular dystrophy devised a unique form of standing up from a squatting position; She held her ankles with her hands to support the weight transfer, fixed the heels, extended the knees to elevate the hips, raised the upper half of the body, and finally stood up. This strategy illustrates the characteristic and specific distribution of the wasted muscle in this disease.

8/108. Chronic demyelinating hypertrophic brachial plexus neuropathy.

    A patient with unilateral, painless, chronic progressive upper limb sensorimotor deficit showed electrophysiological evidence of a focal demyelinating neuropathy with almost complete conduction block across the brachial plexus. magnetic resonance imaging disclosed marked brachial plexus hypertrophy. Intravenous immunoglobulin led to fast and complete recovery, maintained by intermittent perfusions. Hypertrophic brachial plexus neuropathy can be a presentation of focal chronic inflammatory demyelinating polyradiculoneuropathy. Objective and quantitative assessment of hand function is useful to evaluate treatment results and to optimize treatment regimens.

9/108. Self-limited recurrent multifocal neurological symptoms, headache, and cerebrospinal fluid lymphocytic pleocytosis: a benign syndrome with a predilection for young adult men.

    Two young men, aged 34 and 30 years, developed transient recurrent multifocal neurological symptoms with associated severe headache over a 2-week period. Both had a lymphocytic pleocytosis in their cerebrospinal fluid. Cranial imaging studies were normal. All symptoms resolved without recurrence. Although the cause and pathogenesis are undefined, this self-limited benign neurological syndrome may be more common than previously recognized and has a predilection for young adult men.

10/108. osteomalacia that became symptomatic 13 years after a total gastrectomy.

    A 66-year-old man who underwent a total gastrectomy 13 years ago was admitted to our hospital complaining of severe low back pain and muscle weakness. Biochemical examinations revealed hypocalcemia, hypophosphathemia, low serum 25 (OH) vitamin D and hyperparathyroidism. A chest CT scan revealed pseudofractured ribs, whereas plain X-photography did not show any significant findings. We diagnosed the illness as osteomalacia due to malabsorption. The patient has been receiving oral active vitamin d and calcium, and the pain and serum calcium and phosphate values have improved to the point that he can receive out-patient treatment.
