Multiple symmetric lipomatosis associated to polyneuropathology, atrophy of the cerebellum and mitochondrial cytopathy
INTRODUCTION. Multiple symmetric lipomatosis (MSL), which is predominantly found in middle-aged males, is characterised by accumulations of fat in the neck, shoulders and other parts of the trunk, and sometimes associated with different neurological manifestations, both central and peripheral. Although its aetiology is unknown, it has been described as associated with mitochondrial cytopathies. AIMS. To describe the case of a young female with MSL associated with mitochondrial encephalomyopathy. CASE
REPORT. Girl aged 14 with MSL, ataxia, patellar hyperreflexia, bilateral Babinski sign, pes cavus, axonal peripheral neuropathy, involvement of the optic pathway, atrophy of the cerebellum, subsarcolemmal mitochondrial accumulations in the untrastructural examination of the vastus lateralis muscle and partial deficit of complex I in the mitochondrial respiratory chain. As regards molecular genetic aspects, the most frequent mutations of the ATPase 6 gene in lymphocytes, and mtDNA deletions and tRNALys and tRNALeu(UUR) mutations in muscles were excluded.
