    Investigation of Relation Between Visceral and Subcutaneous Abdominal Fat Volumes and Calcified Aortic Plaques Via Multislice Computed Tomography
    (2015) Efe, Duran; Aygun, Fatih; Acar, Turker; Yildiz, Melda; Gemici, Kazim; 0000-0002-9060-2691; 25245049; P-7416-2014; P-5653-2014
    Objective: The present study investigated effect of subcutaneous fat volume and abdominal visceral fat volume on aortic atherosclerosis via multislice computed tomography. Materials and methods: The present study comprised 424 subjects who underwent non-contrast-enhanced abdominal CT in our clinic between June 2012 and June 2013. Using dedicated software visceral fat volume was calculated for each individual and then subcutaneous fat volume was calculated by subtracting visceral fat volume from total fat volume. By dividing visceral fat volume/subcutaneous fat volume participants were assigned to three groups according to their mean visceral fat volume/subcutaneous fat volume: Group 1 consisted of subjects with visceral fat volume/subcutaneous fat volume lower than 0.48 (Group 1< 0.48); Group 2 consisted of subjects with visceral fat volume/subcutaneous fat volume equal to or higher than 0.48 and lower than 0.69 (0.48 <= Group 2< 0.69); and Group 3 consisted of subjects with visceral fat volume/subcutaneous fat volume equal to or higher than 0.69 (Group 3 >= 0.69). Results: The mean abdominal aortic calcium scores according to Agatston scoring (au) were 136.8 +/- 418.7 au in Group 1, 179.9 +/- 463 au in Group 2 and 212.2 +/- 486.9 in Group 3, respectively. Conclusions: We have demonstrated a significant correlation between visceral fat volume and abdominal aorta atherosclerosis, while there was absence of significant correlation between subcutaneous fat volume and abdominal atherosclerosis.

    MRI Findings of Lumbosacral Metastasis from Occult Follicular Thyroid Cancer: Report of A Case
    (2014) Coban, Gokcen; Yildirim, Erkan; Gemici, Kazim; Erinanc, Hilal; https://orcid.org/0000-0002-9057-722X; https://orcid.org/0000-0003-1401-6356; 23129029; P-7533-2014; ABI-3856-2020; AAL-1268-2021
    A 63-year-old female was admitted to our hospital with bowel and bladder incontinence. Magnetic resonance imaging (MRI) showed a 13 x 12 x 12 cm mass invading the posterior regions of the L4, L5, S1 and S2 vertebrae with broad paravertebral soft tissue invasion. A Tru-cut biopsy of the mass was performed. The histopathological examination revealed metastatic follicular carcinoma of the thyroid. Thyroid functional tests were within the normal limits. Thyroid sonography revealed a heterogeneous, ill-defined, 14 x 9 mm hypoechoic solid nodule in the right lobe of the thyroid gland. On thyroid scintigraphy, an area of focal hyperactivity was detected in the right lobe at the nodule localization. Total thyroidectomy was performed, and the primary tumor pathology was determined to be follicular thyroid cancer. To our knowledge, only a few cases of lumbosacral cord compression as the initial manifestation of follicular thyroid carcinoma have been reported in the literature. We aimed to discuss the MRI findings of tumors in this age group with lumbosacral localization.
