A radiological finding suggesting Blake’s pouch cyst: A rare pediatric anomaly associated with hydrocephalus – A case report

Background: Blake’s pouch cyst (BPC) is a rare congenital anomaly resulting from the failure of the embryonic Blake’s pouch to perforate during early fetal development. This condition leads to hydrocephalus, which may lead to increased intracranial pressure and a range of symptoms. According to authors, Indonesia faces infrastructure shortages in performing endoscopic third ventriculostomy or cyst fenestration; not many neurosurgeons are equipped to perform this procedure. The patient was treated with a ventriculoperitoneal (VP) shunt, resulting in good outcomes. Case Description: A 6-month-old female infant was brought to the emergency department, presenting with signs of elevated intracranial pressure, including vomiting and irritability. Computed tomography (CT) scans confirmed the presence of hydrocephalus. Due to limited hospital resources and the high cost associated with endoscopic third ventriculostomy, which requires specialized equipment and expertise not readily available in our setting, a VP shunt procedure was chosen as a more economically feasible treatment option. The procedure significantly improved the patient’s condition, resulting in substantial neurological recovery without complications. Conclusion: A CT scan diagnosis and placement of a VP shunt effectively improved the patient’s outcome, highlighting the differences in treatment in developed countries.
