Lhermitte-Duclos Disease: A Rare Cause of Cerebellar Ataxia.

ABSTRACT: The aim of this study is to describe a case of Lhermitte-Duclos disease (LDD), which is an extremely rare cause of cerebellar ataxia. LDD is an extremely rare type of benign cerebellar mass and usually manifest as features of raised intracranial pressure and cerebellar dysfunction. Patients may remain asymptomatic for many years, and detection of tumor may be by chance on routine magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). A 29-year-old female presented to the outdoor patient department with 18 months history of a headache, which was moderate to severe in intensity, throbbing in nature, localized to the right side of the head, and associated with nausea and photophobia. On examination, she had mild cerebellar dysfunction, and MRI/MRS finding was consistent with LDD. LDD is a rare cause of headache and cerebellar dysfunction in younger age group. Treatment may be individualized, and conservative management with regular follow-up may be a better approach if symptoms are mild and nonprogressive in nature.

Project description:Variants in the ERCC4 gene have been described to be associated with the following autosomal recessive diseases: xeroderma pigmentosum group F (XPF), xeroderma pigmentosum type F/Cockayne syndrome (XPF/CS), Fanconi anemia complementation group Q (FANCQ), and XFE progeroid syndrome (XFEPS). In this paper, we present a case of a 53-year-old Caucasian female patient with rare variants in the ERCC4 gene. When she was 42 years old, falls and loss of balance occurred. At the age of 48, involuntary, uncoordinated movements of the upper limbs and head, tongue stereotypes (licking and extending movements), speech problems (dysarthria), memory deterioration, and hearing loss occurred. Since childhood, she has shown hypersensitivity to UV radiation. The neurological examination revealed chorea syndrome, cerebellar ataxia, dysarthria, and bilateral hearing loss. She has numerous pigmented lesions on the skin. Brain MRI demonstrated massive cortico-subcortical atrophy. The neuropsychological examination revealed dysfunctions in the executive domain in terms of attention, working memory, organizing, and planning activities. The genetic diagnostics was performed which excluded spinocerebellar ataxia types 1, 2, 3, 6, and 17, Huntington's disease, and FMR1 premutation. In the genetic analysis of next-generation sequencing (NGS), two variants: c.2395C > T and c.1349G > A in the ERCC4 gene were identified in a heterozygote configuration. So far, a few cases of ERCC4 gene variants, which are associated with nucleotide excision repair pathways, have been described in connection with symptoms of cerebellar ataxia. In patients with ERCC4 biallelic variants, the adult neurological phenotype can sometimes be the first symptom and reason for access to genetic testing. The aforementioned case highlights the occurrence of rare genetic causes of progressive neurodegenerative diseases in adults, especially with the spectrum of autosomal recessive nucleotide excision repair pathway disorders (NERDs).
