Importance of repeated computed tomography on pediatric traumatic acute posterior fossa subdural hematoma: A case study

Traumatic acute posterior fossa subdural hematoma (PFSDH) is a rare and potentially fatal condition in which the progressed hematoma compresses the brainstem or causes secondary hydrocephalus. Hence, vigilant monitoring of clinical and radiological findings is crucial to detect the typical sudden deterioration, which can occur in the early stages. However, managing pediatric PFSDHs poses additional challenges due to risks associated with radiation exposure from repeat computed tomography (CT) examinations, potentially impeding crucial diagnostic insights. Here, we present a rare pediatric case of fatal acute traumatic PFSDH. Despite undergoing a timely initial CT scan that indicated the presence of PFSDH, the patient experienced sudden deterioration 15 h later and eventually died. No follow-up CT examinations were conducted during this critical period. This case underscores the challenges in managing pediatric PFSDHs, particularly concerning the benefits of repeated CT examinations in initially stable patients.
