Wilson disease (WD) is one of the few curable movement disorders that manifests with varied presentations so that WD needs to be considered in any patient with a movement disorder under the age of 50 years. Although WD is one of the causes of myoclonus, it is rarely seen in WD and usually as an associated finding. We report a case of an adolescent female patient of WD who presented with cortical multifocal myoclonus of 6-month duration with later development of generalized dystonia, extrapyramidal syndrome, and cognitive decline. Kayser–Fleischer ring was present on slit lamp examination. Serum copper, urine copper, serum ceruloplasmin, and magnetic resonance imaging brain were consistent with the diagnosis of WD. Copper chelation was started along with other symptomatic treatments and diet modifications. Myoclonus had resolved by 3-month follow-up with the improvement of other symptoms. This case report emphasizes that myoclonus can be the main and presenting feature of WD.
We report a case of bilateral useless hand syndrome, a rare presenting manifestation of vitamin B12 deficiency. A 38-year-old man, a strict vegetarian and a teacher by occupation, presented with acute onset clumsiness of both hands while performing fine movements. Detailed history-taking, examination of the patient and relevant investigations (complete blood count, serum vitamin B12 and MRI of the cervical spinal cord) were carried out. Laboratory analysis was suggestive of vitamin B12 deficiency and MRI demonstrated a lesion involving the posterior columns of the cervical cord. The patient was diagnosed as a case of non-compressive cervical myelopathy predominantly involving the posterior column due to vitamin B12 deficiency. Acute bilateral useless hand syndrome can be a rare presenting feature of vitamin B12 deficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
