MNGIE is characterized by severe gastrointestinal dysmotility and leads to cachexia, ptosis, external ophthalmoplegia, peripheral neuropathy, and leukoencephalopathy. MNGIE is a rare disorder that can appear any time from childhood to adulthood. Its prevalence is unknown while marked delay in the diagnosis is common. Herein we report a unique case of MNGIE that has an endocrinologic involvement presenting with primary hypogonadism.
