Coincidence of Nemaline Myopathy and Agenesis of Corpus Callosum in a Newborn Infant: Case Report

Abstract

The diagnosis of the hypotonia during neonatal period is difficult. In the neonatal period, acute illnesses and systemic diseases such as sepsis, congestive heart failure and inborn errors of metabolism should be considered in the differential diagnosis of the patients. Congenital disorders that affect nervous system can be the reason of hypotonia. Nemaline myopathy (NM) is a rare congenital myopathy, characterized with slowly progressive or nonprogressive muscle weakness and the inclusions known as nemaline rods characterized by rod-shaped structures (nemaline bodies) in muscle biopsy specimens. The disease can be presented with hypotonia, feeding problems, repeated respiratory infections, and arthrogryposis. Also, agenesis of corpus callosum (ACC) can result in an interhemispheric disconnection , neurologic problems such as mental retardation, and seizures. Unfortunately, there is no curative treatment for both of them. Herein, we report an infant who was admitted with generalized muscle weakness at the neonatal period and diagnosed as ACC with NM.
