“…Using ultrasonography, larger volumes have been described [ 22 ] than accomplished in our study. However, thyroid gland sizes ranging from 3.6-6 cm in length, 1.5-2 cm in width and 1-2 cm depth are reported [ 23 ], which are more in agreement with our study. Finally, as our findings are principally based on the selective differences between the gland volumes in Cases and Controls, any systematic measurement error is of less importance, provided that its similar presence in Cases and Controls.…”

PurposeTo relate the development of post-treatment hypothyroidism with the dose distribution within the thyroid gland in breast cancer (BC) patients treated with loco-regional radiotherapy (RT).Methods and materialsIn two groups of BC patients postoperatively irradiated by computer tomography (CT)-based RT, the individual dose distributions in the thyroid gland were compared with each other; Cases developed post-treatment hypothyroidism after multimodal treatment including 4-field RT technique. Matched patients in Controls remained free for hypothyroidism. Based on each patient's dose volume histogram (DVH) the volume percentages of the thyroid absorbing respectively 20, 30, 40 and 50 Gy were then estimated (V20, V30, V40 and V50) together with the individual mean thyroid dose over the whole gland (MeanTotGy). The mean and median thyroid dose for the included patients was about 30 Gy, subsequently the total volume of the thyroid gland (VolTotGy) and the absolute volumes (cm3) receiving respectively < 30 Gy and ≥ 30 Gy were calculated (Vol < 30 and Vol ≥ 30) and analyzed.ResultsNo statistically significant inter-group differences were found between V20, V30, V40 and V50Gy or the median of MeanTotGy. The median VolTotGy in Controls was 2.3 times above VolTotGy in Cases (ρ = 0.003), with large inter-individual variations in both groups. The volume of the thyroid gland receiving < 30 Gy in Controls was almost 2.5 times greater than the comparable figure in Cases.ConclusionsWe concluded that in patients with small thyroid glands after loco-radiotherapy of BC, the risk of post-treatment hypothyroidism depends on the volume of the thyroid gland.

“…and ). Its posterolateral border was identifiable only when compressed by the common carotid artery in transverse sections of fixed cadavers (Han and Kim, ; Spitzer and Whitlock, ; Ellis et al, ) and CT images (Han and Kim, ; Wegener, ; Moeller and Reif, ), and was not visible in the fresh or fixed cadavers in the present study. This could be because the supine position of the cadavers caused the blood vessels surrounded by the carotid sheath to drop back, and in the fresh state (i.e., before fixation) the thyroid gland was removed without blood vessels.…”

“…The posteromedial border formed an angle in CT images through the isthmus of the thyroid gland (Fig. D) (Han and Kim, ; Wegener, ; Moeller and Reif, ), whereas it appeared as a more acute angle in the fixed state, especially when it extended posterior to the tracheoesophageal groove (Fig. D).…”

Zuckerkandl's tubercle of the thyroid gland: Its location in the anatomical position, and comparative morphology of the same specimens before and after fixation

et al. 2015

The aim of this study was to elucidate the definition of the borders and surface of the thyroid lobe in the anatomical position, and to compare the morphology of Zuckerkandl's tubercle (ZT) in the fresh and fixed states. One hundred thyroid lobes from 50 fresh Korean cadavers were used. The lateral border of the thyroid lobe could be defined as the most lateral margin of its anterior aspect when in the anatomical position. The posteromedial border was the margin that projected toward the trachea or tracheoesophageal groove. The lateral and posteromedial borders, and the posterior surface between these borders, could be identified in most of the fixed cadavers. The posterolateral border could only be identified in the thyroid lobe if there was compression by the internal carotid artery in cross-sectioned specimens and CT images. The ZT was identifiable in 85% of both fresh and fixed specimens. It was identified mainly at the posteromedial border of the thyroid lobe when in the anatomical position, and extended to the tracheoesophageal groove or esophagus. In the fresh state, the ZT projected as a rounded cone with a usually semicircular base, but its shape was very variable in the fixed state. In the present study, the ZT was found at the posteromedial border or posterior surface of the thyroid lobe in both the fresh and fixed states, contrary to most previous reports. The location of the ZT should be established in the anatomical position to avoid confusion.

“…Using frequency (Table 1), which represents the age categorization, these data show that eight patients were females ranging between 15 and 25 years of age (11.11%), 20 patients were aged between 26 and 35 (27.8%), 16 patients were aged between 37 and 47 (22.22%), 14 patients were aged between 48 and 58 (19.4%), seven patients were aged between 59 and 69 (9.72%), and seven patients were aged between 70 and 80 (9.72%). Moeller and Reif (2000) reported the standard female pelvic measurements for the same variables as 2cm, 8cm, 9cm, 12cm and 11cm respectively. The Sudanese female measurements in this study were found to be 2.0cm, 8.31cm, 13.07cm, 12.7cm and 11.6cm respectively.…”

This study aims to investigate the dimensions of the bony pelvis and soft tissue structures and to characterize the normal gynaecological appearance of single Sudanese females using magnetic resonance imaging (MRI). Design/methodology/approach: Seventy-two single females aged between 15 and 80 years were selected using Sagittal T 2 -weighted pelvic MRIs of 1.5 tesla. The determined variables were uterine cervix cranio-caudal, uterus length, pelvis outlet, pelvic cavity and true conjugate, linearly correlated with age. Signal intensity was used to characterize the normal pelvis structures. For the bladder, uterus endometrium, myometrium, cervix, vagina, adenexa, ovaries, Sagittal T 1 ,T 2 and Coronal T 2 -weighted images were used. Findings: There were significant differences in Sudanese results when compared with Afro-American groups. Originality/value: This study may contribute to obstetrics and gynaecology in the future.
