Miller Fisher Syndrome and Boomerang Sign: A Rare Presentation of Typhoid Fever

Abstract

Miller Fischer syndrome (MFS) is a variant of Guillain-Barré syndrome which is characterized by a triad of ataxia, ophthalmoplegia, and areflexia. It is uncommonly associated with systemic illnesses. We present the case of a young boy who came back after a trip to New Delhi in India, who developed MFS. MRI showed a callosal splenial hyperintensity which is called the boomerang sign. The evaluation revealed typhoid fever. This is probably the first such report of MFS associated with this infection.
