A rare lesıon of breast: Hydatıd cyst

Hydatid cyst (HC) is a lesion most commonly seen in the liver but can occur in many parts of the body. Breast involvement with HC  is extremely rare. It can be isolated or accompanied by other organ involvements. In this report, we present a 46-year-old female with  isolated HC located in the right breast. In the ultrasonography and MR images of the patient, the lesion was compatible with the HC,  and homogenous dens lesion was shown on mammography. Diagnosis of HC was confirmed pathological. With this study, it was aimed to emphasize the radiological findings of isolated breast HC

Diagnostic performance and interobserver agreement of CO-RADS: evaluation of classification in radiology practice

PURPOSEWe aimed to evaluate the use of the COVID-19 reporting and data system (CO-RADS) among radiologists and the diagnostic performance of this system.METHODSFour radiologists retrospectively evaluated the chest CT examinations of 178 patients. The study included 143 patients with positive reverse transcriptase-polymerase chain reaction (RT-PCR) test results and 35 patients whose RT-PCR tests were negative but whose clinical and/or radiological findings were consistent with COVID-19. Fleiss’ kappa (κ) values were calculated, and individual observers’ scores were compared. To investigate diagnostic efficiency, receiver operating characteristic (ROC) curves were calculated for each interpreter.RESULTSThe interpreters were in full agreement on 574 of 712 (80.6%) evaluations. The common Fleiss’ κ value of all the radiologists combined was 0.712 (95% confidence interval [CI] 0.692–0.769). A reliable prediction on the basis of RT-PCR and clinical findings indicated the mean area under the curve (AUC) of Fleiss’ κ value as 0.89 (95% CI 0.708–0.990). General interpreter agreement was found to range from moderate to good.CONCLUSIONThe interpreter agreement for CO-RADS categories 1 and 5 was reasonably good. We conclude that this scoring system will make a valuable contribution to efforts in COVID-19 diagnosis. CO-RADS can also be of significant value for the diagnosis and treatment of the disease in cases with false-negative PCR results

The Inguinal Herniation of the Ovary in the Newborn: Ultrasound and Color Doppler Ultrasound Findings

Inguinal hernias in the newborn age group are seldom encountered. In the affected female patient, the ovaries, fallopian tubes, and the intestines may settle in the hernia sac. The early diagnosis of torsion in cases in which the ovary is herniated into the inguinal canal is of utmost importance in order to give surgery the chance of reduction and correction. In this paper, a case of an ovarian herniation into the inguinal canal without the presence of torsion is being presented, and the place of US and CDUS in the differential diagnosis of the situation is being discussed

Does ultrasound-guided fine-needle aspiration biopsy indicated for subcen-timeter thyroid nodules? - Retrospective evaluation of 6-years single-center results

Introduction: Fine-needle aspiration biopsy (FNAB) is commonly used for histopathological evaluation of thyroid nodules and frequently for nodules larger than 1 cm. However, the indications of FNAB are also discussed for the subcentimeter nodules, in recent years. The aim of this study is to investigate the necessity of FNAB for subcentimeter nodules. Materials and methods: The results of 2906 thyroid FNAB evaluated retrospectively which performed between 2012-2017 in Radiology Department of Adana Numune Training and Research Hospital. The nodules greater and smaller than 1 cm in size were compared. In addition, nodules were classified smaller than 1 cm (5-10 mm), 1-1.5 cm, 1.5-2 cm and greater than 2 cm in size and also according to sonographic echogenicity. Malignancy rates were evaluated in each group. Fisher's exact and Pearson’s Chi Square tests were used for statistical analysis and significance was accepted to correspond to p ≤ 0.05. Results: Malignancy rates with 6.5% in subcentimeter nodules are found to be higher and statistically significant (p=0,022). According to echogenicity, malignancy rate was highest in hypoechoic nodules. The most common malignancy was papillary carcinoma. Conclusion: Our findings suggest that the FNAB maybe necessary for subcentimeter nodules and we recommend FNAB for subcentimeter nodules especially if sonographic features, which suggest malignancy such as hypoecogenicity, calcification and irregular borders, are seen. © 2019 A.

A Rare Cause of Obstructive Sleep Apnea Syndrome: Retropharyngeal Lipoma

Lipoma is the most common benign mesenchymal neoplasm. About 16% of lipomas arise in the head and neck region, especially in the posterior neck. Large lipomas that originate from the retropharyngeal space may cause dyspnea, dysphagia, and snoring and occasionally may lead to obstructive sleep apnea syndrome (OSAS). Herein, we report a 45-year-old male patient with OSAS caused by a giant retropharyngeal lipoma with emphasis on CT findings

Intraarterial polidocanol injection for the treatment of peripheral arteriovenous malformations

Peynircioglu, Bora/0000-0002-1457-4721WOS: 000338031200007PubMed: 23904047The purpose of this study was to investigate the efficacy and safety of intraarterial transcatheter administration of polidocanol as an alternative treatment for peripheral arteriovenous malformations (AVMs). The study comprised 10 patients (six males and four females) with a mean age of 28.8 years (range 8-52 years). All patients had trunk or extremity AVMs. Following the administration of general anesthesia or intravenous (IV) sedation, the patients underwent staged intraarterial polidocanol sclerotherapy with or without additional embolizations for their AVMs. The administration of polidocanol was executed by intraarterial infusion through a microcatheter or by direct percutaneous entry into the nidus under ultrasound guidance. A total of 19 sessions were accomplished in 10 patients. Polidocanol was used alone in six of the 19 sessions. In 13 sessions, polidocanol was used in combination with another agent (including n-butyl cyanoacrylate (NBCA), lipiodol, and ethanol) and/or coils. In two sessions, polidocanol was administered percutaneously under ultrasound guidance directly into the nidus documented by arteriography. No major complications occurred. Intraarterial transcatheter administration of polidocanol alone or in combination with other agents is a safe and effective alternative treatment for peripheral AVMs

The comparison of CT fistulography and MR imaging of perianal fistulae with surgical findings: a case-control study

WOS: 000381113400006PubMed ID: 27034072Purpose: The purpose of this study was to evaluate the diagnostic efficacies of CT fistulography and MRI, in the diagnostic work-up of perianal fistula patients. Materials and methods: All 41 patients who were included in the study (36 males and 5 females, with an average age of 41 years) underwent CT fistulography and MRI examinations prior to surgery. The fistula characteristics obtained from these examinations were compared with the surgical findings. The comparative results were evaluated by means of the Kappa analysis method. Results: CT fistulography predicted the correct perianal fistula classification in 30 (73.1%) of the 41 patients, whereas MRI correctly defined fistula classification in 38 (92.7%) of these patients (the K values were 0.621 and 0.896, respectively; with p < 0.001). CT fistulography depicted 29 secondary extensions in 16 patients, whereas MR imaging revealed 28 secondary extensions in 15 patients. A substantial agreement was found between surgical findings and two modalities (K value was 0.789 and 0.793 for CT fistulography and MRI, respectively, with a p value < 0.001). In terms of locations of internal openings, CT fistulography was able to detect the locations in 28 patients (68.2%), whereas MRI was more successful in this aspect, with a number of 35 patients (85.3%). Granulation tissues, inflammation and edema around the fistula, abscesses, and fistular wall fibrosis were also evaluated. Conclusion: CT fistulography and MRI have different advantages in the diagnosis of perianal fistulas. A good command of knowledge concerning the issue may be a key factor in modality decision

An Important Clue in the Sonographic Diagnosis of Internal Carotid Artery Agenesis: Ipsilateral Common Carotid Artery Hypoplasia

A 42-year-old female patient, who had been diagnosed with an occlusion of her left internal carotid artery (ICA) following Doppler ultrasonographic (US) and digitally-subtracted angiographic (DSA) examinations performed in an outer healthcare center in order to eliminate the underlying cause of her complaint of amorosis fugax, later applied to our hospital with the same complaint. At Doppler US performed in our hospital’s radiology department, her right common carotid artery (CCA) was normal, but her left CCA was hypoplastic. The right internal artery (ICA) was validated as normal. At the left side, however, the ICA was apparent only as a stump and it did not demonstrate a continuity. The diagnosis of ICA agenesis was confirmed by the utilization of Doppler US, CT, and DSA imaging, and it was concluded also that ipsilateral CCA hypoplasia could be evaluated as an important clue to the diagnosis of ICA agenesis

Rotator cuff metastases: A report of two cases with literature review

Context: Distant metastases of primary malignancies to the skeletal muscle tissue are a very rare event. Distant metastases that affect the rotator cuff are even rarer, and only a few of cases have been reported so far. Case Report: The present article reports two cases that presented to our hospital with the complaint of shoulder pain and had a soft tissue mass affecting the muscles of the rotator cuff and invading the neighboring bone compartments. One of the patients developed mucoepidermoid cancer metastasis of the submandibular gland, and the other was found to have a malignant epithelial tumor metastasized from the lower lobe of the right lung, whose primary origin could not be diagnosed until the imaging examinations were employed. Ultrasound and magnetic resonance imaging findings are presented in this paper. Conclusion: Metastases to the muscle tissues could be misdiagnosed as primary sarcomas. Because the therapy regiments and prognoses are fairly different for these two entities, the possibility of a metastasis to the muscle tissue must be considered as a differential diagnosis for case of painful soft tissue mass. Ultrasound is very useful in detection of the lesion and acts as a very important tool during guidance for biopsy. Magnetic resonance imaging, however, is a very valuable asset in the evaluation of the borders of the soft tissue mass and its invasive effect on the bony tissues. Particularly when the features such as lobulated contours, peripheral edema, and intratumoral necrosis exist, the possibility of metastases must be considered
