Summary
Familial strio-pallido-dentate calcification, a rare condition, presents with language deficits and extrapyramidal symptoms. Genetic screening of relatives is crucial for early diagnosis in affected families.
Area of Science:
- Neurology
- Radiology
- Genetics
Background:
- Calcification of the dentate nucleus of the cerebellum is observed in 0.3-0.5% of patients on cerebral CT.
- While causes are numerous, familial incidence suggests a genetic component.
- Familial strio-pallido-dentate calcification is a rare genetic disorder.
Observation:
- Two cases (mother and son) presented with poor language and bilateral extrapyramidal syndrome.
- Cerebral CT revealed bilateral calcification of basal nuclei and cerebellar dentate nuclei in both patients.
- Standard laboratory, hormonal, and immunological tests were normal.
Findings:
- The patients met clinical and neuro-imaging criteria for familial strio-pallido-dentate calcification.
- No correlation was found between symptom severity/duration and calcification extent.
- All patients with this calcification exhibit clinical symptoms, primarily language impairment and extrapyramidal signs.
Implications:
- Early identification of familial strio-pallido-dentate calcification is essential.
- Screening first-degree relatives of affected individuals is recommended.
- This highlights the importance of neuroimaging and clinical evaluation in diagnosing rare genetic neurological disorders.
