Meningiomas are the most common type of primary intracranial tumor, yet very few studies have assessed the effects of tumor removal. ⋯ In summary, we conclude that tumor removal in meningioma can be associated with some benefits in cognition.

Patients receiving anticoagulation therapy develop intracerebral hematomas, which are difficult to evacuate during endoscopic surgery. Insufficient thrombin activation results in the gradual conversion of fibrinogen to fibrin, forming dense fibrin bands (FBs) that harden the hematoma. We aimed to investigate the factors contributing to hematoma hardness. ⋯ Tough hematomas were histologically characterized by high FB density. Preoperative PT-INR and APTT may predict the presence of tough hematomas.

The aim of this study was to synthesize existing knowledge regarding the anatomy of the cavernous sinus (CS), critically evaluate the current anatomical hypotheses concerning its walls, to conduct anatomical dissections and develop a comprehensive understanding of the connective tissue structure of the CS. ⋯ The dural anatomy of the CS involves an intricate interplay between the meningeal and periosteal dural layers, which is elucidated more effectively through the application of fundamental principles informed by embryological development.

This article presents a case study of a 7-year-old female patient with a history of acute myelogenous leukemia, previously treated with chemotherapy. The patient developed acute right peripheral facial paralysis and right upper limb weakness, leading to the discovery of an extra-axial solid lesion at the right cerebellopontine angle. ⋯ The article discusses the clinical presentation and radiological findings, emphasizing the importance of magnetic resonance imaging in diagnosis. It details typical imaging characteristics of cerebellopontine angle chloromas and differentiates them from other intracranial tumors.
