Abstract
Background
Gunshot injuries of the posterior fossa are rare and may follow a fatal course. In posterior fossa gunshot injuries, cerebellar hematoma, contusion, obstruction of cerebrospinal fluid (CSF) circulation by the shrapnel, and intracranial hypertension caused by autoregulation loss lead to mortality in the early stage.
Methods
In this study, four cases of patients who underwent surgical intervention after penetrating shrapnel injuries of the pure posterior fossa were evaluated.
Results
All of the patients were male; their mean age was 26.5 ± 5 years. The lowest and highest Glasgow Coma Scale scores were 4 and 12, respectively. Neural injury was detected by computed tomography performed after systemic and neurological examination following admission to the emergency service. The shrapnel was found in the cerebellar tissue in three cases and in the fourth ventricle in one case. Following preoperative procedures, surgery was performed with the patient in the prone position. Postoperative monitoring revealed no CSF fistula, meningitis, or hydrocephalus. None of the patients required revision surgery. There were no postoperative mortalities.
Conclusion
Due to the small volume of the posterior fossa, acute pathologies may lead to rapid neurological deterioration and death. Early surgical intervention and close postoperative follow-up after penetrating shrapnel injuries of the posterior fossa play a significant role in reducing mortality and morbidity.
