Case report: Diagnosis and treatment of delayed epidural pyogenic abscess after brain tumor operation: a report of 5 cases and review of the literature.

Objective: To explore the clinical manifestations and treatment of delayed epidural pyogenic abscess after brain tumor surgery.

Method: To retrospectively analyze the medical records of 5 patients with delayed epidural pyogenic abscess after brain tumor surgery in our hospital from January 2010 to December 2020, including clinical manifestations, laboratory results, imaging findings, treatment measures, prognosis, etc. The causes of epidural abscesses were analyzed, and the treatment methods and prognosis were evaluated.

A simple and successful treatment for rupture and defect of the posterior third superior sagittal sinus caused by open depressed skull fracture: A case report.

It is extremely dangerous to treat the posterior third of the superior sagittal sinus (PTSSS) surgically, since it is usually not completely ligated. In this report, the authors described the case of a 27-year-old man with a ruptured and defective PTSSS caused by an open depressed skull fracture, which was treated by ligation of the PTSSS and the patient achieved a positive recovery. The patient's occiput was hit by a height-limiting rod and was in a mild coma.

Adult rhabdomyosarcoma originating in the temporal muscle, invading the skull and meninges: A case report.

Background: Rhabdomyosarcoma (RMS) is a rare malignant tumor of mesenchymal origin that mainly affects children. Spindle cell/sclerosing RMS (SSRMS) is even rarer. It is a new subtype that was added to the World Health Organization disease classification in 2013.

Benign cervical intramedullary cyst without an epithelial lining：a case report.

This paper presents a female, benign intramedullary cyst case aged 66-year-old. During the operation, it was found that the cystic wall was very thin, and the cystic fluid was colorless and transparent. The lesion with the capsule was removed partially.

Traumatic pseudoaneurysms of external carotid artery branch: Case series and treatment considerations.

Purpose: To explore the diagnosis and treatment of traumatic external carotid branch pseudoaneurysms.

Methods: Eleven cases of traumatic external carotid artery branch pseudoaneurysms were admitted in our hospital. Digital subtraction angiography was performed in all patients.

Intracranial inflammatory myofibroblastic tumor: a report of two cases.

We report two cases of Intracranial inflammatory myofibroblastic tumor (IMT) with recurrent, cystic, and venous sinus occlusion. The cases show imaging progression from a small lesion (case 1) or absence of lesions (case 2). One of cases recurred 2 years after surgery and was treated with corticosteroids but the tumor was still growing and was resected again.

Endoscopic transsphenoidal approach to a sphenoid sinus inverted papilloma combined with pituitary adenoma: a case report.

Sphenoid sinus inverted papilloma (IP) is a very infrequent tumor, and the combination of sphenoidal IP with pituitary tumor is extremely rare. In this report, the authors describe the case of a 63-year-old male with oculomotor nerve palsy in the left eye due to sellar region tumor. After endoscopic transsphenoidal surgery, the postoperative pathological examination confirmed the co-occurrence of an sphenoidal IP and pituitary adenoma.

Effect of Podophyllotoxin Conjugated Stearic Acid Grafted Chitosan Oligosaccharide Micelle on Human Glioma Cells.

Objective: To study the physiochemical characteristics of podophyllotoxin (PPT) conjugated stearic acid grafted chitosan oligosaccharide micelle (PPT-CSO-SA), and evaluate the ability of the potential antineoplastic effects against glioma cells.

Methods: PPT-CSO-SA was prepared by a dialysis method. The quality of PPT-CSO-SA including micellar size, zeta potential, drug encapsulation efficiency and drug release profiles was evaluated.
