Case Reports
Delayed subaponeurotic fluid collection on an infant's head: Underreported case and review of the literature.
Delayed subaponeurotic fluid collection (DSFC) is a relatively uncommon problem, probably under reported soft swelling in the scalp which usually develops in infancy that occurs weeks to months after birth. Although the exact etiology remains unclear, several theories have been postulated such as (i) cerebrospinal fluids (CSF) leak from microfractures of the skull and (ii) disrupted lymphatic drainage, gradually liquefying subaponeurotic bleeding. Here, we reported typical clinical findings of DSFC and analysis of the fluid aspirate from our patient. To the best of our knowledge, this is the first case reported from Asia, particularly from Indonesia. ⋯ Herein, we reported the first DSFC case from Indonesia. With no previous experience of the condition, a definitive diagnosis was possible through a very carefully physical examination and history taking, along with a good communication among the neurosurgeon, pediatrician, and the clinical pathologist.

Case Reports
A rare case of vaccine-induced immune thrombosis and thrombocytopenia and approach to management.
The use of the COVID-19 vaccines Vaxzevria from AstraZeneca and Covishield from Janssen has been associated with sporadic reports of thrombosis with thrombocytopenia, a complication referred to as vaccine-induced immune thrombotic thrombocytopenia (VITT) or vaccine-induced prothrombotic immune thrombocytopenia. It presents commonly as cerebral sinus venous thrombosis (CSVT), within 4-30 days of vaccination. Females under 55 years of age are considered to be especially at high risk. Mortality up to 50% has been reported in some countries. Identification of early warning signs and symptoms with prompt medical intervention is crucial. ⋯ The patient was successfully treated with intravenous immunoglobulin and discharged after 19 days in ICU. Although she was left with long-term neurological deficits, an early presentation and a multidisciplinary approach to management contributed toward a relatively short stay in hospital and avoided mortality.

Intraoperative mapping techniques maximize safety and efficacy during perirolandic glioma resection but may induce seizures and limit the procedure. We aim to report the incidence and predictors of stimulation-induced seizures during mapping either patient is awake or under general anesthesia (GA). ⋯ Awake craniotomy with intraoperative mapping can be done safely for perirolandic gliomas with lower but statistically nonsignificant incidence of intraoperative seizures and this could be attributed to statistically significant lower stimulation intensities required for mapping. Preoperative multiple AEDs and low-grade glioma are significant predictors for intraoperative seizures.

In this paper, we report a clinical series of skull base lesions operated on trough the MiniPT, extending its application to skull base lesions, either using the classical minipterional or a variant, we call extradural minipterional approach (MiniPTEx). ⋯ We further advance the indications of the MiniPT by extending it to operate on the cranial base tumors or complex vascular lesions without additional morbidity. MiniPT approach may be safely associated with skull base techniques, including anterior and posterior clinoidectomies, peeling of the middle fossa, transcavernous approach, and anterior petrosectomy. The versatility of the MiniPT craniotomy and the feasibility of performing skull base surgery through the MiniPT technique have been demonstrated in this paper.

Endoscopic endonasal transclival approaches provide direct access to the ventral skull base allowing the treating of clival and paraclival pathology without the manipulation of the brain or neurovascular structures. Postoperative spinal fluid leak, however, remains a challenge and various techniques have been described to reconstruct the operative defect. The "gasket seal" has been well-described, but has anatomic challenges when applied to clival defects. We describe a modification of this technique for use in endonasal transclival approaches. ⋯ We describe the successful use of a simple, low risk, and technique modification of the "gasket seal" technique adapted to the clivus that allows for hard reconstruction and facilitates placement of the nasoseptal flap.
