Abstract:

Objective: The aim of this study was to evaluate the anatomy of dural venous sinus variations through three-dimensional phase-contrast (3D-PC) magnetic resonance venography (MRV). Awareness of the normal anatomical variations of venous sinuses and apparent MRV flow gaps prevent misdiagnosis of dural venous sinus diseases. Materials and Methods: The dural venous sinuses were assessed using nonenhanced 3D PC-MRV. Of these 968 patients, 154 were excluded due to venous thrombosis and mass invasion. A total of 814 patients (186 male and 628 female) were included in the study. Results: The most comm

Abstract:

Objectives: Magnetic resonance venography (MRV) is a widely used non-invasive imaging technique to diagnose cerebral dural venous sinus thrombosis (CVST) and intracranial venous abnormalities. Non-visualization of a dural venous sinus is diagnostic of CVST on MRV. However, there are numerous common variances and technical aberrations on MRV that mimic filling defects and might be confused with CVST, making diagnosis difficult. These include aberrant veins and missing, hypoplastic or asymmetric venous sinuses. In addition, reconstruction artifacts might take the form of flow gaps with various l

Abstract:

Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncin

Abstract:

Introduction: The dural venous system, composed of various sinuses, plays a crucial role in draining deoxygenated blood from the central nervous system. Understanding its anatomical variations is essential to differentiate it from pathological conditions like cerebral venous sinus thrombosis. This study aims to evaluate the anatomical variations of the dural venous sinuses using Magnetic Resonance Venography.Methods: An observational, cross-section study was performed in the Department of Radiology from September 2023 to March 2024 after the approval by the Institutional Review Committee (Refe

Abstract:

Menière&apos;s disease (MD) is a chronic inner ear disorder characterised by vertigo, fluctuating hearing loss, and fullness, frequently associated with migraine. The aetiology of MD is multifactorial but unclear. Endolymphatic hydrops (EH) is the histopathological marker. The correlation between venous disorders and MD is described in the literature. Our study aims to evaluate the incidence of Transverse Sinus Asymmetries (TSA) in patients with Menière Disease (MD) and non-migrainous headaches to test a physiopathological hypothesis. &lt;i&gt;Materials and Methods&lt;/i&gt

Abstract:

Absence of frontal sinus is usually associated with various syndromes such as craniosynostosis, osteodysplasia, down syndrome etc. Geographically, absence of frontal sinus is seen usually in areas with cold climate. This paper reports a case of 18-year old Indian woman suffering from bilateral absence of frontal sinuses which was non-syndromic in conjunction with unilateral mandibular hypoplasia. The paper also highlights the clinical significance of frontal sinus which was non-syndromic absence and its rarity in warm climate such as in South East Asian regions and the treatment options of uni

Abstract:

The evaluation of maxillary sinus volumes is fundamental for pre-surgical planning in this area, as well as for the diagnosis of sinusitis and the diagnosis and treatment of maxillary hypoplasia. This study aimed to assess changes in sinus volume over time as a function of different conditions, such as sex, orthodontic treatments like rapid palate expansion, and the presence of edentulism. The Cone-Beam Computed Tomographies of eighteen patients were selected, and their entire sinus volumes were segmented, enabling the measurement of the sinus volume in three spatial dimensions.

In the territorial hospital, left internal carotid artery significant stenosis was suspected. Neurological examination and laboratory tests were normal. A neck vascular ultrasound was performed, showing a low bifurcation of the left common carotid artery (CCA) and a hypoplastic left internal carotid artery (ICA) with a sinuous path at the cervical level. Therefore, a computed tomographic (CT) angiography examination of the head and neck vessels

Objective: We sought to determine whether an accessory maxillary ostium (AMO) is a congenital or acquired condition and we investigated concomitant sinus pathologies associated with this structure. Methods: Paranasal sinus CT examinations of individuals aged ≥13 years and <13 years were compared retrospectively. In total, 552 sinuses of 276 patients aged ≥13 years (Group 1) and 284 maxillary sinuses of 142 children aged <13 years (Group 2) were evaluated. Patients were classified as AMO-positive or -negative. The following features were evaluated in Group 1: AMO presence, mucus retention

Abstract:

ABSTRACT Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus-related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a complex and long-lasting process, there are great structural variations between individuals. Maxillary and/or frontal sinus aplasia or hypoplasia are more common than the other types. Several degrees

<p class="abstract"><strong>Background:</strong> Paranasal sinuses are a group of four paired air filled spaces surrounding the nasal cavity. During the developmental process, anatomical variations can occur in consequence of intra and extramural migration of the ethmoidal air cells, over pneumatization or hypoplasia of the sinuses and bulging of the neurovascular structures to the sinuses, thereby affecting the drainage pathways, causing chronic infections and complications during functional endoscopic sinus surgery (FESS).
