Mirror aneurysm of ICA terminus associated with adult polycystic kidney disease
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2021) Erok, Berrin; Win, Nu Nu; Can, Orçun; Çizmeli, Muzaffer Olcay
Introduction. Bilatereal saccular cerebral aneurysms (SCAs) that developed symmetrically on the same named vessels are defined as mirror aneurysms and account for a small subset of multiple cerebral aneurysms. The internal carotid artery (ICA) bifurcation is a rare location for mirror aneurysms. Aim. We aimed to present the importance of risk status assessment for SCAs and screening in all ADPKD patients for timely detection and managementof SCAs before catastrophic complications occur Description of the case. We present mirror aneurysms of bilateral ICA bifurcation that appear like a couple of dancing men on coronal computed tomography angiography (CTA) images, which were successfully treated with single stage coil embolization in a 45 year old female patient with medical history of autosomal dominant policystic kidney disease (ADPKD). Conclusion. SCAs are more frequent in patients with ADPKD than in general population and also these aneurysms are more likely to rupture at earlier ages. Mirror aneurysms of ICA terminus can be treated effectively and safely by single stage coil embolization.
Pericallosal berry aneurysm associated with azygous anterior cerebral artery – a case report
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2021) Erok, Berrin; Win, Nu Nu; Tatar, Sertaç
Introduction. Azygos anterior cerebral artery is a rare variant of the anterior segment of the circle of Willis caused by an unusual fusion of the normally paired A2 segments of the anterior cerebral artery (ACA). Despite its rare occurrence, it is associated with various vascular and structural cerebral abnormalities, particularly berry aneurysms. Aim. We aimed to present a case of a 41-year-old female patient who presented to our neurology department with complaints of headache. Description of the case. She had a positive paternal history of aneurysmal subarachnoid hemorrhage. Magnetic resonance angiography (MRA) of her brain revealed an azygos ACA (bifurcating into two pericallosal arteries) which was associated with a saccular aneurysm at its bifurcation point. She was referred to the interventional radiology department for preventive endovascular treatment. Conclusion. Azygos ACA carries a high risk of aneurysm development and its occlusion can potentially compromise blood supply to both cerebral hemispheres. It is therefore crucial for clinicians to be aware of its significance and to report its presence in angiographic studies.
The use of medial clavicular epiphysis ossification stages for bone age determination
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2021) Win, Nu Nu; Erok, Berrin
Introduction. Bone age determination is a radiological method investigating the compatibility of ossification processes of bones with chronological ages. Aim. We aimed to investigate the use of CT staging of the medial clavicular epiphyseal ossification in bone age determination in Turkish adolescents and young adults. Material and methods. Chest CT exams of 2018 patients between 11 and 35 years of age were retrospectively evaluated for epiphyseal ossification stages of the bilateral medial clavicles (4036 clavicles) on both axial&coronal images and compared with the sex and chronologic age of the individuals in Turkey. Results. For stage 2,3 and 4 the ages of women were greater than men and it was statistically significant. For an individual classified as stage 4,it can be said with certainty that he or she has already reached the age of 18.There was no statistically significant difference between left&right sides and between the axial&coronal images.In addition, it was found that the medial clavicular head epiphyses showed a lot of variation. Conclusion. CT evaluation of the medial clavicular epiphysis ossification stages is helpful in determination of the individuals over the age of 18. Regardless of the sex, the stage 4 can be used as a criterion to make the prediction that an individual is older than 18 years.
