Resumo
The rectus abdominal muscle is part of the anterior abdominal wall, having three to six bellies. In only one
of the 106 dissections already made in the “Faculdade de Ciências Médicas de Minas Gerais” Anatomy
Laboratory was found a male cadaver who did not have inferior venter of this muscle bilaterally. Instead, at the
left side, was found a tendon that measured 5.5 cm laterally and 12 cm medially, and at the right side, there
was the same variation with a 15.5 cm length tendon, rising in the upper branch of the pubis and crest pubis.
Despite being a rare variation, individuals who have showed it have increased potential for physiological and
surgical complications, in case they need interventions using inferior rectus abdominis muscle venter’s snips.
