We report the phenotype of spinocerebellar ataxia type 36 (SCA36), which is a novel type of dominant cerebellar ataxia nicknamed as "Asidan," caused by the expansion of a hexanucleotide GGCCTG repeat in intron 1 of the nucleolar protein 56 (NOP56) gene. Age at the onset of ataxia was 53.1 (3.4) years (mean[SD]). Truncal ataxia was the most frequent initial symptom (100%), followed by ataxic dysarthria (100%), limb ataxia (93%), and general hyperreflexia (79%). Tongue fasciculation and subsequent atrophy were observed in 71% of the cases, especially in those of a longer duration. Skeletal muscle fasciculation and atrophy in the limbs and trunk were also observed in 57% of the cases. To our knowledge, we describe for the first time a unique clinical feature of Asidan (SCA36)--relatively pure cerebellar ataxia with progressive motor neuron involvement during the course of disease-that puts SCA36 at the crossroad of SCA and amyotrophic lateral sclerosis.

Paraneoplastic cerebellar degeneration (PCD) can occur severely and appear as subacute cerebellar syndrome. PCD may be associated with small cell lung cancer, adenocarcinoma, breast cancer, ovarian carcinoma, and Hodgkin's lymphoma. An 11-year-old male was admitted with acute cerebellar ataxia, dysarthria, and diplopia. Mediastinal conglomerated lymph nodes were depicted in a chest computed tomography (CT) examination, and diagnosis of stage IV Hodgkin's lymphoma was obtained after a lymph node biopsy. The antibodies against Purkinje cells (anti-Tr antibody) were positive immunohistochemically. Thus, paraneoplastic cerebellar degeneration depending on Hodgkin's disease was diagnosed. Despite the completion of chemotherapy, neurological recovery was not observed in the patient and plasmapheresis with immunoadsorption, and intravenous immunoglobulin (IVIG) was performed. Truncal ataxia, gait disturbance, and tremors decreased. Consequently, we thought that plasmapheresis with the immunoadsorption method and IVIG therapy might be a treatment option for cerebellar ataxia caused by a mechanism of immune ancestry.
