Motor neuron disease in a young female, Madras pattern or Brown-Vialetto Van Laere syndrome? - A diagnostic dilemma

Venkata Durga Sasishekar T, Sai Krishna Y, Sathya Sahi A, Keerthi Vyas


We report a case of a 14 year old female patient with progressive ponto-bulbar palsy, bilateral deafness and distal muscle weakness with wasting. This pattern is seen in Brown-Vialetto-Van Laere which is an extremely rare neurological disorder of unknown etiology with less than 80 cases being reported till date. The syndrome was first described in 1894 by Brown and subsequently by Vialetto in 1936 and Van Laere in 1966. A similar pattern is noted in the Madras form of motor neuron disease which is seen in South India. With the available literature and data it's difficult to differentiate between these entities.
