Malignant fibrous histiocytoma (MFH) is a pleomorphic mesenchynal sarcoma. It is uncommonly arises primarily from the intra-peritoneal cavity. Primary peritoneal MFH with tumor bleeding and rupture is rare. We describe the imaging features of a 70-year-old patient presenting with ruptured hemorrhagic peritoneal MFH at subhepatic area,accompanied by massive hemoperitoneum,mimicking a ruptured pedunculated hepatocellular carcinoma. Computed tomography (CT) revealed a large heterogeneous enhanced subhepatic mass with adjacent liver,gallbladder and colon invasion. Tumor hemorrhage and rupture complicated with peritoneal seeding and massive bloody ascites were also detected. Angiography showed a hypervascular tumor fed by enlarged right hepatic arteries,cystic artery and omental branches of gastroepiploic artery. The patient underwent laparotomy for tumor resection,but the tumor recurred one month after operation. To our knowledge,the CT appearance of ruptured intraperitoneal MFH complicated by hemoperitoneum has not been previously described.

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.
