Variations in the origins of the thyroid arteries on CT angiography

ObjectiveTo investigate the anatomical variations in the origins of the thyroid arteries on CT angiography images.MethodsThe presence and the origins of the superior thyroid artery, the inferior thyroid artery, and the thyroidea ima artery were retrospectively evaluated based on carotid CT angiography examinations. The bifurcation level of the common carotid artery with respect to the cervical vertebrae and disc spaces was also determined. A total of 640 patients were included in the study.ResultsThe right and left superior thyroid arteries arose from the external carotid artery in 413 (64.5%) and 254 (39.7%) patients, from the bifurcation of the common carotid artery in 131 (20.5%) and 148 (23.1%) patients, and from the common carotid artery in 90 (14.1%) and 226 (35.3%) patients, respectively. We could not observe the right and the left superior thyroid arteries in 6 (0.9%) and 12 (1.9%) of the patients, respectively. However, the right and left inferior thyroid arteries were not identified in 14 (2.2%) and 45 (7%) of the patients, respectively. The thyroidea ima artery was detected in 2.3% of the patients.ConclusionThe visualization of thyroid arteries on CT angiography images enables the anatomy of the arterial supply system of the thyroid gland to be explored in a noninvasive manner prior to surgery.

The effect of anatomic differences on the relationship between renal artery and diaphragmatic crus

BACKGROUND The aim of this study is to investigate the effect of anatomic differences on the relationship between renal artery and diaphragmatic crus via the touch of two structures. MATERIALS AND METHODS The study included dynamic computed tomography (CT) scans of 308 patients performed mainly for characterisation of liver and renal masses. Anatomic differences including the thickness of the diaphragmatic crus, the localisation of renal artery ostium at the wall of aorta, the level of renal artery origin with respect to superior mesenteric artery were evaluated. Statistical relationships between renal artery-diaphragmatic crus contact and the anatomic differences were assessed. RESULTS Thickness of the diaphragmatic crus at the level of renal artery origin exhibited a statistically significant relationship to renal artery-diaphragmatic crus contact at the left (p < 0.001) and right side (p < 0.001). There was a statistically significant relationship between high renal artery origin and renal artery- -diaphragmatic crus contact at the left (p < 0.001) and right side (p = 0.01). The localisation of renal artery ostium at the wall of aorta (right side, p = 0.436, left side, p = 0.681) did not demonstrate a relationship to renal artery-diaphragmatic crus contact. CONCLUSIONS Thickness of the diaphragmatic crus and high renal artery origin with respect to superior mesenteric artery are crucial anatomic differences determining the relationship of renal artery and diaphragmatic crus.

Diagnostic Value of Ultrasound Elastography Characterization of Solid Breast Lesions

Objective: In this study, the contribution of ultrasound (US) elastography in the characterization of solid breast masses was investigated. Methods: Seventy-five patients (1 male and 74 female, aged between 19 and 80 years) were enrolled. A total of 75 solid breast lesions, for which a biopsy was planned, were evaluated using B-mode US and US elastography during the same session. Using B-mode US, the lesions were classified according to the Breast Imaging Reporting and Data System (BI-RADS); Tsukuba elasticity score was determined and strain ratio was calculated for all lesions. Subsequently, a core biopsy of the lesions was performed. BI-RADS results, Tsukuba elasticity scores, and strain ratio were compared with the histopathological results. Results: Of 75 lesions, 47 were benign (62.66%) and 28 were malignant (37.33%). According to the Tsukuba scoring method, the mean score of benign and malignant lesions was 2.31 and 3.96, respectively. The mean strain ratio was calculated to be 4.97±2.94 (0.96–13.20) for malignant lesions and 2.27±1.41 (0.5–5.84) for benign lesions. In statistical analysis, the mean strain ratio of the malignant lesions was significantly higher than that of the benign lesions (p<0.05). BI-RADS classification had the highest sensitivity (89.3%), and the Tsukuba scoring method had the highest specificity (93.6%). Elastographic assessment altered the result in 6 of 8 patients (75%) that B-mode US was non-diagnostic Conclusion: The combination of B-mode US and US elastography can significantly improve the accuracy of diagnosis and characterization of breast lesions, thereby reducing the unnecessary biopsy rate.

Dev konka bülloza piyoseli

Konka bulloza,havalanmis (pnomatize) veya icinde bir havali hucre bulunan orta konka icin kullanilan bir terimdir. Genellikle asemptomatik olmakla birlikte pnomatizasyonun buyuklugune ve nazal septumla olan iliskisine gore burun tikanikligi semptomlari verebilir ve ostiomeatal komplekse basi olusturmakta ise tikanmasina neden olarak sinuzite yol acabilir. Piyosele donusmesi nadirdir. Dev konka bulloza endoskopIk muayenede orta konkanin genislemis bir bolumu olarak gorulur. Konka bulloza kesin tanisi paranazal sinus bilgisayarli tomografisi (BT) ile koyulur. Tedavisinde endoskopik olarak orta konkanin lateral parsiyel rezeksiyonu yeterli ve minimal invazif bir yontemdir. Bu yazida sag nazal pasaji tamamen tikayan ve nazal vestibule kadar uzanim gosteren ve ayni tarafta sinuzite yol acan tek tarafli dev konka bulloza piyoseli olgusu sunulmustur
