Abstract
Tubular aggregates (TAs) are inclusions described in skeletal muscle in a variety of disorders. In a retrospective analysis, TAs were found in 18 (0.24%) cases and involved a spectrum of clinical phenotypes. Ultrastructurally, four distinct types of aggregates were noted. There was no correlation between the clinical phenotypes, duration of illness and types of TAs.
