Persistent hydrocephalus is common in children after resection of posterior fossa tumours. However, occurrence of subdural hygroma is very rare. We report the case of a 14-month-old child who presented at a paediatric neurology clinic in Muscat, Oman in 2021 who developed a tense subdural hygroma with stable hydrocephalus, in the early postoperative period, following posterior fossa tumour resection. We describe the distinctive clinical, radiological and pathological features associated with the development of a tense subdural hygroma. We also discuss the management by cerebrospinal fluid diversion, which includes either a ventriculoperitoneal or subduroperitoneal shunt. This unique condition is distinguished from external hydrocephalus by features that are critical to the management strategy.

Objective: Subdural fluid collection is a common neurosurgical condition in the pediatric population. Patients requiring surgical intervention have historically been managed with subdural drains, subdural-subgaleal shunting, subdural-peritoneal shunting, and mini-craniotomies. An alternative procedure for patients with an open anterior fontanelle is bedside transfontanelle drainage.

Article Synopsis
  • The study examined the viability and impact of 3D-printed external cranial protection devices (ECPD) in preventing complications after unilateral decompressive craniectomy (DC).
  • A cohort of 44 patients was evaluated, with 24 using the ECPD and 20 receiving standard treatment, showing no significant differences in overall outcomes but a notable reduction in specific complications like subdural effusion for the ECPD group.
  • Results suggest that while the ECPD is safe and helps reduce some complications post-DC, it does not significantly enhance patient prognosis, indicating the need for additional research.

Article Synopsis
  • - The text discusses a 3D-printed external cranial device designed to protect the head after a decompressive craniectomy, which is a surgery that removes part of the skull to relieve pressure on the brain.
  • - The study reports that using this device significantly reduces the formation of contralateral subdural effusion, helps correct midline shift, and aids in neurological recovery.
  • - It includes information on the design, manufacturing process of the device, and features comparative CT images of a patient to illustrate its effectiveness.

Arachnoid cysts have the potential to rupture, leading to the development of a subdural hygroma following minor trauma. Although surgery may be considered in cases of increased intracranial pressure (ICP) or regional neurological symptoms, the optimal approach remains unclear. We report a case of subdural hygroma due to a ruptured arachnoid cyst (SHrAC) with elevated ICP successfully treated with long-term subdural drainage for over 1 month.

To explore the clinical effects of a 3D-printed intracranial pressure balancing device in preventing complications after suboccipital craniectomy (DC). This study is a retrospective cohort analysis. The clinical data of 35 patients who underwent DC at Department of Neurosurgery, Beijing Chaoyang Hospital, Capital Medical University, from September 2020 to September 2023 were reviewed.
