The authors discuss the experimental data and information concerning the clinical use of a siloxane elastomer for repairing a defect in the dura mater in 40 patients with various cerebral pathology. Observation over the patients in postoperative periods of up to 34 months, the results of autopsy and repeated operations, and experimental data allow the suggested material to be considered quite adequate and possessing definite advantages over other materials used for the purpose.

A potential two-way passage of cells and substances between the brain and skull bone marrow may open for new insights into neurological disease. The arachnoid membrane was traditionally considered to restrict cells and larger molecules in CSF from entering the dura and bone marrow directly. However, new data on exchange between brain and skull bone marrow have recently emerged.

Calcified chronic subdural hematoma (CCSDH) is a rare condition characterized by the accumulation of calcified blood between the dura mater and arachnoid membrane, typically following remote trauma. These lesions often present as space-occupying, extra-axial masses over the cerebral convexity and can mimic extra-axial tumors, such as calcified meningiomas. A 73-year-old male with a history of prostate cancer, hypertension, and hyperlipidemia presented with vision changes and mild papilledema.

The purpose of the current study was to determine the angulation of the dural venous sinuses in soft tissue, to evaluate differences between types of tissue, and to discuss the potential influence of these angulations on intracranial venous hemodynamics and related pathologies. Angulations formed in different segments of the transverse, sigmoid, and superior sagittal sinuses were measured in 13 adult human cadaveric heads (26 sides). After the soft tissues were removed, measurements were also taken from the underlying bone.

Subdural hematoma (SDH) is bleeding between the dura mater and the brain surface, often visualized as a crescent-shaped lesion on computed tomography (CT). However, some SDHs can appear as a biconvex hyperdense lesion mimicking an acute epidural hematoma. Encapsulated acute SDH (EASDH), a rare subtype characterized by a fresh hematoma within the subdural fibrous capsule, presents with similar CT findings.
