This article provides a comprehensive description of the morphology of the human petrosquamosal sinus (PSS) derived from original observations made on 13 corrosion casts of the cranial venous system combined with routine clinical imaging studies in two patients. The PSS is not a rare finding in the adult human. In particular, continuous developments in imaging techniques have made radiologists become increasingly aware of this anatomical entity in recent years. The role of the PSS as a major encephalic drainage pathway and its potential implication in pathological conditions such as intracranial venous hypertension are discussed.

The petrosquamosal sinus is a rare and almost unknown emissary vein of the temporal bone. It traverses the middle cranial fossa along the petrosquamosal fissure and connects dural sinuses with extracranial venous networks. It is known to undergo normal involution during fetal and early postnatal life, and therefore is rarely found in humans.

Purpose Of The Study: Körner's septum (KS) is a developmental remnant formed at the junction of mastoid and temporal squama, representing the persistence of the petrosquamosal suture. During mastoid surgery, it could be taken as a false medial wall of the antrum so that the deeper cells might not be explored. The aim of the study was to assess a Körner's septum prevalence and to analyze its topography.

Objective: The petrosquamosal sinus (PSS) is clinically important as it represents a potential hemorrhagic hazard during neurosurgical procedures. This double-approach radiologic study and meta-analysis aimed to assess the imaging characteristics of the PSS on computed tomography (CT) and systematically analyze its prevalence to improve imaging accuracy and assist in neurosurgical management.
Methods: The retrospective radiologic study included CT scans of 388 patients aged 18 years or older.

The author has encountered a 67-year-old man with dural arteriovenous fistula (AVF) presenting as a non-traumatic chronic subdural hematoma (CSDH). This previously healthy patient was hospitalized due to progressive headache with subacute onset. He underwent burr-hole surgery twice for evacuating the left CSDH that was thickest at the posterior temporal area.

BACKGROUND The aim of the study was to determine the prevalence of petrosquamosal sinus (PSS) and other temporal bone (TB) anatomical variations in various patients using high-resolution computed tomography (CT). MATERIAL AND METHODS We reviewed clinical and consecutively obtained CT data for 276 TBs of 138 patients. The incidence of TB anatomical variations was compared among patients with radiological markers of chronic otitis media (RCOM) and non-RCOM.
