RESUMO
The most common developmental anomaly of midgut rotation and fixation is non-rotation. Symptomatic intestinal malrotation is relatively common in infants and children but uncommon in later ages. Most adult cases are silent throughout life and are not discovered unless they cause acute or chronic abdominal pain. Many such patients have ill-defined abdominal complaints and are labeled as having a "functional" disorder since no definite clinical abnormalities are found other than the subjective complaints. The most frequent symptomatic presentation in the adult is midgut volvulus the symptom of which is usually self-limited although often recurrent and sometimes leading to an abdominal catastrophe. The diagnostic means for the adulthood malrotation include simple and contrast radiographic studies and CT scan. Malrotation first detected by cholescintigraphy is rare. We report a case of intestinal non-rotation incidentally discovered on DISIDA hepatobiliary scintiscan.
