Summary
This case report details the second Danish family diagnosed with cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL). Early misdiagnosis highlights the importance of considering CADASIL in patients with neurological symptoms and specific MRI findings.
Area of Science:
- Neurology
- Genetics
- Vascular Neurology
Background:
- Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leucoencephalopathy (CADASIL) is a rare genetic disorder.
- It affects small blood vessels in the brain, leading to strokes and cognitive decline.
Observation:
- A Danish family presented with neurological symptoms initially misdiagnosed as multiple sclerosis.
- Magnetic Resonance Imaging (MRI) revealed characteristic leucoencephalopathy in the external capsule and anterior temporal lobes.
- Negative cerebrospinal fluid (CSF) findings and a suggestive family history prompted further investigation.
Findings:
- Diagnosis was confirmed through skin biopsy showing granular osmiophilic material (GOM) and genetic testing revealing a NOTCH3 mutation.
- This case highlights the diagnostic challenges and variability in CADASIL presentation.
Implications:
- Early and accurate diagnosis of CADASIL is crucial for patient management and genetic counseling.
- Increased awareness of CADASIL's diverse symptoms, including migraine and early-onset dementia, is essential for clinicians.
- This case contributes to understanding CADASIL prevalence and diagnostic pathways in Denmark.
