Adult sporadic neuronal intranuclear inclusion disease with tremor as the initial presentation:A case report and literature review
Neuronal intranuclear inclusion disease(NIID)is a slowly progressive rare neurodegenerative disease with the pathological feature of the appearance of eosinophilic clear intranuclear inclusions in the nervous system and vis-ceral organs,and it has complex and diverse clinical manifestations and lacks specificity,which often leads to misdiagno-sis or missed diagnosis.In recent years,skin biopsy and genetic testing have provided a basis for the diagnosis of NIID.This article reports a patient with NIID who had upper limb tremor as the main manifestation and was finally diagnosed by genetic testing,analyzes the clinical features of this patient,and summarizes the latest research advances in NIID through literature review,so as to improve the understanding of this rare disease among clinicians.
