Dural Venous Sinus Cyst: Clinical and Imaging Findings.

Dural venous sinus cysts are very infrequent lesions, generally asymptomatic and incidental. These cystic lesions may include venous structures continuing with superficial cortical veins. A 23-year-old male patient presented with a severe headache.

Effect on ophthalmic imaging findings of flow-diverting stent treatment covering the origin of the ophthalmic artery.

Background: Flow-diverting stents are devices that are increasingly used in the treatment of intracranial aneurysms and expand the spectrum of endovascular treatment. The patency of side branches and perforators is a major concern about flow-diverting stent (FDS) treatment.

Methods: From 2011 to 2020, seventy-eight patients in whom the orifice of the ophthalmic artery was covered during FDS treatment were evaluated in this study.

The coexistence of newly diagnosed acromegaly with primary empty sella: More frequent than expected?

Objective: We investigated the coexistence of newly diagnosed acromegaly with primary empty sella (ES), which is considered to be a rare association, and the impact of ES on the laboratory, radiological and prognostic status of acromegaly.

Design: Acromegaly patients diagnosed and followed-up between 2012 and 2021 were included. Empty sella was defined as the pituitary gland and adenoma filling <50% of the sella turcica on preoperative T1 magnetic resonance imaging (MRI).

Computed Tomography-Guided Lumbar Puncture: Advantages and Disadvantages.

Objective: This study aimed to evaluate the utility of computed tomography (CT) guidance in difficult lumbar puncture (LP) cases, which had a history of at least one unsuccessful blind attempt at LP (no imaging guidance), and to note potential advantages and disadvantages of the use of CT guidance.

Methods: In total, 32 CT-guided LP procedures performed between June 2019 and March 2021 were included. All LP indications were recorded.

The role of CT angiography and endovascular treatment in acute-massive head and neck bleeding.

Purpose: To report the results of the endovascular treatment of acute-massive head and neck bleeding in a single center and underline the value of computerized tomography-angiography and endovascular treatment of this desperate patient group.

Methods: Forty-eight patients who suffered from acute-massive head and neck bleeding and in whom conservative treatment options had failed were included in the study. To localize the site of the bleeding, computerized tomography-angiography was obtained above the supra-aortic level.

An Alternative Endovascular Technique for Vein of Galen Aneurysmal Malformation Treatment: Etylene Vinyl Alcohol Co-Polymer Embolization via Double-Lumen Balloon Microcatheter.

Aim: To present an alternative endovascular treatment option for the vein of Galen aneurysmal malformation by ethylene-vinyl alcohol copolymer embolization via a double-lumen balloon microcatheter.

Material And Methods: A female patient was suspected with the vein of Galen aneurysmal malformation in the prenatal period and diagnosed choroidal type vein of Galen aneurysmal malformation. Once the patient was symptomatic with severe cardiac failure, an endovascular treatment decision was made.

Three-dimensional ultrasonographic evaluation of carotid artery plaque surface irregularity.

Introduction: The aim of this study was to evaluate 3-dimensional (3D) ultrasonography (US) in determining the surface irregularity of carotid artery plaques.

Material And Methods: This study included 50 patients (20 females and 30 males) aged between 56 and 82 years with plaques in the carotid artery which were detected during routine neck ultrasound. Simultaneously these cases were evaluated in terms of plaque echogenicities and surface characteristics with 2D and 3D US.

Evaluation of Cortical Brain Parenchyma by Diffusion and Perfusion MRI Before and After Chronic Subdural Hematoma Surgery.

Aim: To evaluate microcirculatory changes in neighboring parenchyma as a result of pressure due to chronic subdural hematoma (CSDH) in early and late periods after hematoma drainage.

Material And Methods: The subject group consisted of 25 patients who underwent CSDH drainage. Brain diffusion and perfusion magnetic resonance images (MRIs) were obtained preoperatively, and at 48 hours (early period) and 2 months (late period) postoperatively.
