Intraparenchymal fiberoptic intracranial pressure monitoring and decompressive craniectomy in meningioma case with critical intracranial pressure: A case report during COVID-19 pandemic

Introduction: Meningioma is a slow-growing tumor that can cause neurological emergency due to intracranial hypertension. The definitive therapy is indeed emergency resection, but it is not always possible in several countries due to limited capacity and/or capability of the emergency operating room. The use of intraparenchymal fiberoptic intracranial pressure (ICP) monitoring and decompressive craniectomy (DC) in cases of brain tumors might be possible, but it is uncommon. We report a meningioma patient in whom immediate meningioma resection was considered too risky due to intensive care unit (ICU) shortage during COVID-19 pandemic and, therefore, underwent these procedures as life-saving measures. Case presentation: A 24-year-old man was brought to the emergency room with a chief complaint of seizure. Physical examination was notable for decreased consciousness (Glasgow Coma Scale (GCS) 11) and a dilated left pupil with intact light reflex. A contrasted Brain CT Scan revealed extra-axial mass on the left sphenoid with extensive tentacle edema, which pushed the midline structures 2 cm toward the contralateral side. Discussion: The patient was diagnosed with Left Sphenoid Meningioma. We decided to perform intraparenchymal fiberoptic ICP monitor insertion and DC considering the situation, device availability, safety, and efficacy. The patient slowly regained consciousness in the recovery room after the procedure. The best-observed GCS was 12. Two weeks afterward, the patient came back to our outpatient clinic neurologically intact. The patient was then planned for elective tumor resection. Conclusion: ICP monitoring and DC are not commonly performed on brain tumor cases. However, in suboptimal situations, these procedures might save lives. The present case showed that ICP monitor and DC were helpful in times of ICU shortage.
