Aim: This study aims to investigate the role of diffusion-weighted imaging (DWI) in enhancing the diagnostic accuracy of adult posterior fossa tumors.
Materials And Methods: A prospective cross-sectional study was conducted involving 20 patients with suspected CNS posterior fossa tumors. MRI scans were performed using a 1.5 Tesla machine with appropriate sequences, including DWI. Data analysis was performed using descriptive statistics.
Results: The study revealed that the majority of posterior fossa tumors occurred in the age group of 61-70 years, with medulloblastoma being the most common tumor subtype. Male patients were more prevalent than females, and DWI showed hyperintensity in the majority of lesions. The reported sensitivity and specificity of DWI were high, indicating its effectiveness in tumor evaluation.
Conclusion: In conclusion, this study provides valuable insights into the epidemiology, clinical features, and radiological characteristics of adult posterior fossa tumors. It underscores the significance of advanced imaging techniques like DWI in improving diagnostic accuracy and guiding clinical management decisions for these challenging neoplasms.

Pituitary neuroendocrine tumors (PitNETS) are common intracranial tumors, but extrasellar or ectopic PitNETS are very rare and supposed to originate from some pituitary remnants. They are mostly found in sphenoidal sinus. But particularly, ectopic clival PitNETS are highly aggressive and can cause bone invasion and can be misdiagnosed as other lesions of the skull base such as chordomas.

The craniofacial morphology in patients with syndromic craniosynostosis varies from one spectrum to another. Our study aims to explore the craniofacial morphology and growth pattern in patients with Apert and Crouzon syndrome. This study involved 39 computed tomographic scans of skull (Apert = 11, Crouzon = 10, Control = 18), divided into 2 age subgroups.

Purpose: The location of the sigmoid sinus may change according to the ventilation status of the mastoid bone, in which case the relationship of the sigmoid sinus to the facial nerve and semicircular canals is predicted to change. The purpose of this study was to evaluate the importance of sigmoid sinus distances to the facial nerve and semicircular canals concerning mastoid surgery.
Methods: The relationship of the sigmoid sinus and the facial nerve with the semicircular canals was analyzed from the cone beam computed tomography images of 75 male and 95 female subjects, aged 18-65 years.

The divergence of the maxilla from the pterygoid process of the sphenoid bone forms the pterygomaxillary fissure, which lies in the medial part of the infratemporal fossa. It transmits the posterior superior alveolar nerve and the terminal segment of the internal maxillary artery and connects the infratemporal fossa with the pterygopalatine fossa. The purpose of this study is to evaluate the height, width and distance of the pterygomaxillary fissure from the zygomatic bone, articular tubercle, and zygomatico-temporal suture.

Background: Shunt nephritis, although rare, should be high in the differential diagnoses for patients with gross or microscopic hematuria and a history of a ventriculoatrial/cystoatrial shunt.
Observations: The authors present the case of a 31-year-old female with a history of a resected posterior fossa hemangioblastoma and hydrocephalus, who presented to the nephrology clinic with night sweats and tea-colored urine for 3 months after being hospitalized for a saddle pulmonary embolism; kidney biopsy was contraindicated. The patient had hypocomplementemia, nephrotic-range proteinuria, positive proteinase 3-specific antineutrophil cytoplasmic antibody, and dysmorphic red blood cells in the urine sediment.
