Central nervous system-associated lesions can frequently be found in abusive head trauma (AHT) cases. Since there are frequently no visible signs of injury on the body surface, the diagnosis of AHT can be challenging. In particular, if the affected child shows only isolated neurological symptoms, these are often misinterpreted as a minor illness.

Objectives: Estimating the age of injury in pediatric abusive head trauma (AHT) is a challenging task but potentially valuable for the identification of perpetrators. The aims of the study are (1) to describe the temporal development of different imaging features of subdural collections (SDCs), and (2) to provide novel age-diagnostic reference data for forensic-radiological expert reports.

Methods: Using a multi-center approach and a 10-year study period, serial neuroimaging studies of 13 comprehensively investigated AHT cases (8 CT and 26 MRI scans) were analyzed regarding several subdural imaging parameters (SDC appearances, entities, components, and associated findings).

Clinical Issue: The diagnostics of physical child abuse are usually performed by a multidisciplinary team and frequently represent a clinical challenge. Radiological expertise is particularly important for the recognition of abusive injuries to the skeletal system and the central nervous system. The aim of the article is to give an overview of red flags of child abuse in radiological imaging.

Background: The expert opinions on forensic age diagnostics requested by state institutions are used to show the exceeding of legally relevant age thresholds, especially the completed 18 year of life. According to the recommendations of the Study Group on Forensic Age Diagnostics (AGFAD), this requires - among other things - a determination of skeletal age.

Method: Considering recent scientific knowledge, the current conditions and established skeletal age diagnostics methods are presented.

Article Synopsis
  • Subdural collections (SDCs) are critical findings in abusive head trauma (AHT) cases, with various forms such as subdural hematoma and hygroma being analyzed for their prevalence and impact on forensic injury age estimation.
  • A retrospective study of 56 documented AHT cases found that most children exhibited multiple SDCs, with the mixed appearance pattern being frequent, while the newly developed classification system highlighted the complexity of these patterns.
  • The study concluded that signs of recent brain injury were present in nearly all cases, and there were no significant differences between confession and non-confession groups, supporting the reliability of AHT diagnostic criteria.
