Аннотация
BACKGROUND: Balo's concentric sclerosis (BCS) is a rare variant of multiple sclerosis (MS) that usually runs a benign course. Typically, brain magnetic resonance imaging (MRI) shows concentric lamella of areas of demyelination alternating with normal zones of myelin preservation. Clinically, it may be mistaken for other intracranial space-occupying lesions, especially in our subregion, where neuroimaging facilities are scarce or not affordable. The authors report a rare case of BCS in a young Nigerian male diagnosed and managed in Enugu, Nigeria. This is possibly the first reported case in sub-Saharan Africa.
CASE DESCRIPTION: The patient presented with behavioral changes, focal seizures, cranial neuropathy, long tract signs, and cerebellar dysfunction causing severe disability and functional impairment with a Modified Rankin Score (mRS) of 4. Brain MRI showed multiple heterogeneous lesions in the right cerebral hemisphere, brainstem, and cerebellum with features in keeping with BCS. Cerebrospinal fluid oligoclonal bands were negative and C-reactive protein was normal. He had high-dose steroids and immunosuppressive therapy. He made a gradual neurological improvement and significant symptom resolution and was able to return to work after a year (mRS-1).
CONCLUSION: BCS is a rare variant of MS in sub-Saharan Africa. The mainstay of diagnosis is MRI which shows the typical concentric demyelinating pattern. Steroids and immunosuppressive therapy are effective in the treatment of BCS.
