    Abstract Aim: Thyroid fine needle aspiration biopsy (FNAB) is an inexpensive and microinvasive procedure used in the diagnosis of thyroid nodules. However, cytology may be insufficient in up to 40% of biopsies. This study aimed to assess the effect of radiological features of thyroid nodules on cytological adequacy. Methods: The patients who underwent thyroid FNAB between 2016 and 2019 in our clinic were reviewed in this retrospective cohort study. Diagnostic adequacy rate and radiological features of nodules (size, cystic component, calcification content, echogenicity, margin feature) were noted and their relationship was investigated. Results: A total of 525 patients (77% female, 23% male; mean age 53.3 years; age range 14-87) had FNAB for 595 nodules. Mean diameter of the nodules was 20.1 mm (min: 4mm; max: 60 mm). Of the all biopsies, 25% were inadequate for diagnosis. Adequacy was significantly low in nodules containing macrocalcification (P=0.036). There was no significant relationship between adequacy and echogenicity, margin feature, solid structure or size of the nodules (P>0.05 for each). Conclusion: Some radiological features may be predictive of inadequate sampling. Nevertheless, varied extrinsic factors affect cytopathological adequacy besides radiological features. Additional techniques may be required in these nodules.

    Abstract Idiopathic granulomatous mastitis (IGM) is a benign chronic inflammatory disorder of the breast tissue, with unknown etiology. IGM is extremely rare among male gender. In this case report, we present a male patient with superficial high grade bladder cancer, who was complaining of a palpable mass in his right breast for two weeks following intravesical Bacillus Calmette–Guerin (BCG) treatment. There was an assymetrical, mass-like density without distinct contours in retroareolar area of the right breast. US guided core-needle biopsy was performed. Histopathology confirmed the diagnosis of IGM. To our knowledge, this is the first case of IGM following intravesical BCG administration.

    Abstract Aim: Tuberculosis diagnosis may be challenging and percutaneous biopsy may be required for definitive diagnosis. In this study, we aimed to investigate the utility of percutaneous biopsy in diagnosis of tuberculosis and radiological features of the tuberculosis cases diagnosed by image-guided biopsy. Methods: The patients who were diagnosed with tuberculosis by image-guided biopsy between 2016 and 2020 in our institution were reviewed retrospectively in these case series. Histories of malignancy or immune deficiency, age and genders of the patients, localizations and radiological imaging findings of the lesions, needle types, imaging methods used for the biopsies and presumptive diagnoses before the biopsies were noted. Results: A total of 16 patients (5 Females, 11 Males) with a mean age of 41 years (range: 17-74 years) had image-guided biopsy with presumptive diagnosis of infection or malignancy. Four patients had transthoracic core-needle-biopsy for lung masses, 12 had curettage-bone-biopsy for lytic lesions of vertebral and pelvic bones under CT-guidance. Four of the patients had immune deficiency and one had a history of malignancy. All patients were diagnosed with tuberculosis by both histopathological and culture analysis. Conclusion: Image-guided-biopsy is safe and useful in the diagnosis of tuberculosis cases who could not be diagnosed by laboratory and sputum tests or those with presumptive diagnoses of malignancy. Tuberculosis should be kept in mind during percutaneous biopsy of radiologically suspicious cases as a differential diagnosis, even though they are clinically negative.

    Abstract Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome virus coronavirus 2 (SARS-CoV-2). As known, COVID-19 has become a global pandemic and serious health problem. Disease mainly affects lungs and common findings are fever cough and shortness of breath. Computerized tomography (CT) has an important role in initial evaluation and follow up of COVID-19. Main (CT) finding of the disease is bilateral extensive ground-glass opacification (GGO) with a peripheral or posterior distribution, mainly involving the lower lobes. In this case report, we present a pneumothorax and subcutaneous emphysema case in a patient with COVID-19. To the best of authors’ knowledge, it is the first illustrated case of pneumothorax accompanying COVID-19 pneumonia.

    Abstract Background: Osteoid osteoma (OO) is one of the most commonly occurring benign bone tumors. It constitutes 10-12% of benign bone tumors and 2-3% of primary bone tumors. In radiofrequency ablation (RFA) treatment, the cells of the tumor are thermally inactivated by the help of electrodes shaped like needles. In our study, we aimed to show the major and minor complications in patients undergoing RFA and to show what should be done to prevent these complications.
    Methods: The study was carried out as a prospective study on the follow-up of 87 osteoid osteoma patients treated between 2015 and 2017. The youngest of the patients was 1 year old and the oldest was 42 years old. The RFA procedure lasted 10 min on average, excluding anesthesia and preparation. All lesions were ablated at 90 degrees for 7 minutes with the heat increased gradually. All patients were followed up for 1 day in the orthopedics clinic.
    Results: Complications were observed in 7 patients. The lesions with the most complications were observed to be in the tibia, second-degree burns were seen in 2 patients, and superficial skin infection was observed in 2 patients. In 1 patient, the probe tip was broken and remained within the bone. Intramuscular hematoma was detected in 1 lesion located in the proximal femur. A complaint of numbness in the fingers developed in a lesion located in the metacarpus.
    Conclusion: Preventive measures should be taken before the procedure in order to prevent minor complications, and, for major complications, close follow-up should be done after the procedure and patients should be kept away from heavy physical activities for the first 3 months.

    Abstract Objective: We used the results from the first three screening rounds of Bahcesehir Mammography Screening Project (BMSP), a 10-year (2009-2019) and the first organized population-based screening program implemented in a county of Istanbul, Turkey, to assess the potential cost-effectiveness of a population-based mammography screening program in Turkey.Materials and Methods: Two screening strategies were compared: BMSP (includes three biennial screens for women between 40-69) and Turkish National Breast Cancer Registry Program (TNBCRP) which includes no organized population-based screening. Costs were estimated using direct data from the BMSP project and the reimbursement rates of Turkish Social Security Administration. The life-years saved by BMSP were estimated using the stage distribution observed with BMSP and TNBCRP.Results: A total of 67 women (out of 7234 screened women) were diagnosed with breast cancer in BMSP. The stage distribution for AJCC stages O, I, II, III, IV was 19.4%, 50.8%, 20.9%, 7.5%, 1.5% and 4.9%, 26.6%, 44.9%, 20.8%, 2.8% with BMSP and TNBCRP, respectively. The BMSP program is expected to save 279.46 life years over TNBCRP with an additional cost of $677.171, which implies an incremental cost-effectiveness ratio (ICER) of $2.423 per saved life year. Since the ICER is smaller than the Gross Demostic Product (GDP) per capita in Turkey ($10.515 in 2014), BMSP program is highly cost-effective and remains cost-effective in the sensitivity analysis.Conclusion: Mammography screening may change the stage distribution of breast cancer in Turkey. Furthermore, an organized population-based screening program may be cost-effective in Turkey and in other developing countries. More research is needed to better estimate life-years saved with screening and further validate the findings of our study.
