The radiologist's role in child abuse: imaging protocol and differential diagnosis

Reports of Maltreatment in a Children's Hospital: Evaluation of the Epidemiological Profile and Its Relationship with the Outcome in Fractures

Objective  To describe suspected/confirmed cases of child maltreatment related to fractures in a pediatric hospital in southern Brazil. Method  Study of the Information System of Notifiable Diseases notifications and the victims' medical records between January/2016 and December/2020. Variables related to the victim, the perpetrator, the type of abuse, the presence of fractures, and their anatomical location and death were evaluated. Logistic regression was performed to identify fracture-related variables, adjusted for sex and age. The results were expressed in odds ratios and their respective 95% confidence intervals. It was considered significant p  < 0.05. Results  There were 276 cases, 73 infants (26.4%), male predominance (151, 54.7%), with authorship of the mistreatment by relatives (245, 96,0%), 85 (31,5%), they presented fractures, with five deaths (1.9%). Factors related to the presence of fracture: age of the victim (less than two years old; n  = 82; or 2.48; 95% CI: 1.45 - 4.25), having more than two aggressors involved ( n  = 144; or 2.09; 95% CI: 1.16-3.75), the medium being traffic/automobile accident, ( n  = 52; or 2.65; 95% CI: 1.04-6.75), consult an orthopedist ( n  = 91; or 6.77 / 95% CI: 3.66-12.51), and the need for surgical intervention ( n  = 15; OR 36.72; 95% CI: 8.22-164.03). Conclusions  The importance of suspicion, early identification of aggression, and the correct completion of notifications for activating the system of guaranteeing rights and removal of the aggressor was emphasized.

Multiple Bony Injuries on Bone Scan in a Case of Unsuspected Child Abuse

This case is described of an eleven-month-old infant with lower limbs swelling and the left elbow skeletal malformation following a fall. The radionuclide bone scan was performed to exclude bone infection or congenital skeletal anomaly. The images unexpectedly showed multiple increased radioactive foci throughout the whole body. It was a strong probability of child abuse. All lesions are readily apparent on the following plain film radiographs and MRI.
