ABSTRACT
BACKGROUND/AIMS: This study aimed to examine the frequency and type of asymptomatic neurological involvement in inflammatory bowel disease (IBD) using cranial magnetic resonance imaging (MRI). METHODS: Fifty-one IBD patients with no known neurological diseases or symptoms and 30 controls with unspecified headaches without neurological origins were included. Patients and controls underwent cranial MRI assessments for white matter lesions, sinusitis, otitis-mastoiditis, and other brain parenchymal findings. RESULTS: The frequencies of white matter lesions, other brainstem parenchymal lesions, and otitis-mastoiditis were similar in IBD patients and controls (p>0.05), whereas sinusitis was significantly more frequent in IBD patients (56.9% vs 33.3%, p=0.041). However, among those subjects with white matter lesions, the number of such lesions was significantly higher in IBD patients compared to controls (12.75+/-9.78 vs 3.20+/-2.90, p0.05 for all). CONCLUSIONS: The incidence of white matter lesions seemed to be similar in IBD patients and normal healthy individuals, and the lesions detected did not pose any clinical significance. However, long-term clinical follow-up of the lesions is warranted.
