An Alternative Mechanism for the Instant Removal of Hypervascular Anaplastic Meningioma with Recovery of Mentality with NaCl + KCl

引用

Case Reports in Clinical Medicine 2024年第7期13卷 213-218页

作者： Chur chin Department of Emergency Medicine New Life Hospital Bokhyun-Dong Daegu South Korea

Background: There is limited information regarding adjuvant treatment for malignant meningiomas. Although external whole-brain irradiation is recommended, the patient’s family in our case rejected this modality. Notably, traditional chemotherapy was ineffective. Aim: I speculated if the exfoliation of graphene could disassemble the three-dimensional (3D) structures of the graphene because the tumor mass or the blood clots including the graphene consisted of inhomogeneous materials. Therefore, I aimed to explore another possible mechanism for the instant removal of inhomogeneous materials. Method: Herein, I report a case of anaplastic papillary meningioma. A 59- year-old man presented with partial complex seizures and recurrent headaches following craniotomy for the removal of a mass with a right frontotemporal convexity 10 years ago. Computed tomography (CT) and magnetic resonance imaging demonstrated a right frontotemporal mass with diffuse contrast enhancement and extensive surrounding edema. A right frontotemporal flap was performed. The tumor and the infiltrated dura were removed, but massive intraoperative bleeding occurred and the right middle cerebral artery was clipped at the M2 territory. Postoperatively, the follow-up CT scan revealed hydrocephalus. Accordingly, a ventriculoperitoneal shunt was placed. The patient suffered from left hemiplegia as a sequela of intraoperative bleeding. Four months later, the follow-up CT scan showed chronic epidural hematoma in the right frontotemporoparietal region. The patient also had an altered level of consciousness. Results: The patient’s level of consciousness was restored after infusion of a NaCl + KCl solution with instant disappearance of the mass. Conclusion: There may be another mechanism for disassembling the inhomogeneous graphene-containing complex, such as quantum fluctuation of the graphene exfoliation with pair annihilation or relation to tissue engineering by the graphene.

1 Background Congenital heart disease(CHD)is the most common major congenital anomaly,affecting approximately one in every 100 live births[1].Among congenital anomalies,66%of preventable deaths are due to CHD,and 58%of the avertable morbidity and mortality due to congenital anomalies would result from scaling congenital heart surgery services[2].Every year,nearly 300,000 children and adults die from CHD,the majority of whom live in low-and middle-income countries(LMICs)[3].Approximately 49%of all individuals with CHD will require surgical or interventional care at some point in their lifetime[4];as a result of advances in access to and the delivery of such services,over 95%of children born with CHD in high-income countries now live into adulthood[3].Here,adults have surpassed children in the number of CHD cases at a ratio of 2:1[5].
