Intraparenchymal intracranial pressure monitoring in patients with acute liver failure.

Background: Elevated intracranial pressure (ICP) is a common cause of death in acute liver failure (ALF) and is determinant for decision-making regarding the timing of liver transplantation. The recommended type ICP monitoring device is controversial in ALF patients. Epidural devices had less risk of hemorrhagic complications, but they are less reliable than intraparenchymal ones.

Reactive lymphoid follicular hyperplasia mimicking a peripheral nerve tumor.

Background: Reactive lymphoid follicular hyperplasia is a benign proliferation of lymphoid follicles, which can develop wherever lymphoid tissue is present. We present the unique case of an RLFH that involved the radial nerve and presented as a peripheral nerve tumor.

Case Description: A 62-year-old woman came to our attention because of the evidence of a mass in her right arm, associated with numbness in the lateral aspect of her right arm and forearm.

Histological findings in cerebellar tonsils of patients with Chiari type I malformation.

Objectives: Cerebellar tonsillectomy is often performed for relief of symptoms associated with Chiari type I malformation (CMI). Nonetheless, the idea of removing supposedly healthy central nervous tissue has been a source of concern for neurosurgeons. The aim of this paper is to determine the histological changes in the cerebellar tonsils of patients with a wide range of symptoms and conditions related to CMI.
