PURPOSE: We wanted to evaluate the MDCT findings and concomitant injuries of traumatic adrenal injury in children. MATERIALS AND METHODS: Among 375 children who had undergone a MDCT scan for abdominal trauma during the recent five years at our institution, 27 children who had revealed adrenal injury on their CT scan were included in the study. We retrospectively evaluated the causes of the trauma, the patterns of adrenal injury, the associated CT findings and the concomitant injuries of the other organs in the abdomen. RESULTS: We identified 27 children (7.5%) (17 boys and 10 girls, mean age: 9.9 years, range: 2-18 years) with adrenal injury. The causes of adrenal injury were a traffic accident for 20 patients (74%), falls for four patients (15%) and blunt trauma for three patients (11%). The right adrenal gland was injured in 20 patients (74%), while the left adrenal gland was injured in three patients and bilateral involvement was noted in four patients. The patterns of adrenal injury were round or oval shaped hematoma in 23 lesions (74%), irregular hemorrhage with obliterating the gland in six lesions (19%) and active extravasation of contrast material from the adrenal region in two lesions (7%). Concomitant injuries were noted in 22 patients (81%), including 15 patients with liver laceration (56%), 11 patients with lung contusion (41%) and nine patients with renal injury (33%). CONCLUSION: The frequency of adrenal injury was 7.5%. The right adrenal gland was more frequently involved. Concomitant organ injury was noted 81% of the patients and the most frequently involved organ was the liver (56%).
