This paper describes a 20 year old woman with a new combination of neurological impairments in which the motor phenomena were responsive to corticosteroid treatment. She had lifelong moderate learning impairment. A variable ataxia with cerebellar characteristics was present from early life, with early severe exacerbation when seizures were uncontrolled. Atypical absence and simple and complex partial seizures were present from the first year of life and EEG abnormalities were maximal in the right parietal region, concordant with a mild non-specific abnormality of the white matter in the region of the trigone. Episodes of alternating hemiplegia occurred from 11 years, unassociated with seizures. Exercise induced dystonia occurred from the age of 5. After 10-20 minutes walking, her right foot would turn in and the right leg would stiffen, followed by the left and by falling and inability to get up for several minutes. Prednisolone improved her ataxia and was associated with cessation of both seizures and exercise induced dystonia. This adds a new syndrome to the corticosteroid responsive motor disorders associated with epilepsy.

We report a case of neurosarcoidosis in which urodynamic studies showed neurogenic bladder dysfunction. A 30-year-old man began to have slowly progressive gait ataxia of vestibular origin, deafness, and hallucination, which developed into versive seizure and stupor. Brain computed tomography and magnetic resonance imaging showed the anteromedial frontal lobe lesion with mild ventricular enlargement. The cerebrospinal fluid examination revealed pleocytosis with raised total protein and angiotensin-converting enzyme levels. Endoscopic lung biopsy showed epithelioid granuloma. Oral prednislone (60 mg/day) ameliorated his symptoms. After tapering steroids, however, he developed urinary urgency, frequency, urge urinary incontinence, and a relapse of gait ataxia. The urodynamic study showed detrusor hyperreflexia. Prednisolone treatment again improved his urinary and neurological symptoms. The anteromedial frontal lobe lesion seems to be responsible for the micturitional disturbance in our patient with neurosarcoidosis.

The objective of this work was to evaluate the long-term efficacy of a proposed therapeutic protocol in 12 dogs with a tentative diagnosis of degenerative myelopathy, followed-up for a 6-month period. Twelve dogs fulfilling the antemortem inclusion criteria (breed, age, adequate vaccination, history of progressive posterior ataxia and/or paraparesis, no radiographic and myelographic abnormalities in the spinal cord and vertebral column) were allocated. All these dogs presented signs of thoracolumbar syndrome (T3-L3), scored as grade I (mild to moderate ataxia and paraparesis) in 10 and grade II (severe ataxia and ambulatory paraparesis) in 2 cases. Treatment included the use of epsilon-aminocaproic acid and N-acetylcysteine, supplemented with vitamins B, C and E. Prednisolone was given for the first two weeks and upon worsening of neurological signs. Daily exercise, performed as walking or swimming, was strongly recommended. Clinicopathological evaluation was normal in all 12 dogs, and survey radiographs and myelograms did not show spinal cord compression. Magnetic resonance imaging (MRI), performed only in 4 dogs, did not disclose compressive disorders or intramedullary lesions. Neurological signs were progressively worsening in all 12 animals, eventually resulting in severe paraparesis (grade III) or paraplegia (grade IV). The applied medications do not appear to be an attractive alternative to conservative management (physiotherapy) or euthanasia in canine degenerative myelopathy, irrespective of its chronicity.

We report the case of a 33-year-old man with diplopia, sleepiness, and paresthesia of the left upper limb that were slowly progressive. On admission, he presented with restriction in the vertical movement of the eyes and abduction of the right eye, and horizontal and convergence nystagmus. Slight weakness of the left upper limb, bilateral Babinski sign, and truncal ataxia were also noted. Cerebral magnetic resonance imaging was performed, and gadolinium-enhanced T1-weighted imaging revealed a mass lesion that involved the diencephalon and the corpus callosum, which was invariably enhanced. Specimens obtained using a brain biopsy showed epithelioid granuloma with the presence of foreign body giant cells and lymphocytic infiltration. Prednisolone was administrated because we suspected neurosarcoidosis, but the clinical symptoms worsened with the enlargement of the lesion. A re-evaluation of the biopsy specimens using immunohistochemistry revealed tumor cells of germinoma that were scattered among the lymphocytes and positive for periodic acid-Schiff staining, placental alkaline phosphatase, and c-kit. A combination of chemotherapy and radiation resulted in clinical improvement and marked reduction of the mass lesion in size. We concluded that the possibility of germinoma should be considered in case granulomatous inflammation is observed in brain biopsy specimens.
