A Rare Case of Partial Unilateral Corpus Cavernosum Agenesis With Concomitant Multiple Genitourinary Anomalies.

Congenital penile agenesis is a rare condition with an incidence of 1 in 30 million, while other congenital malformations of the cavernous bodies are much less common. In a few cases in the literature, it has been reported that the reason for consulting a physician with these conditions is the insufficient erection. As a first reported case, we present a 16-year-old male patient with partial unilateral corpus cavernosum agenesis accompanying genitourinary anomalies.

What are the requirements for patient-centered breast imaging? Communication preferences of mammography patients in Turkey.

We have investigated communication preferences of mammography results in 90 patients through a structured interview approach. About 81% of patients expressed that they wanted to get the results, and 18% expressed that getting the results does not help if they are incomprehensible. In patients who want to get the results, 80% preferred face-to-face interaction with physicians, whereas the others preferred other modes of communication to prevent loss of time. Majority of patients infavor of face-to-face interaction (57%) preferred both the referring physician and the radiologist. Comprehensibility and fast delivery of reports, plus direct communication with radiologists are the requirements in mammography patients while implementing patient-centered radiology.

Non-squamous cell carcinoma diseases of the larynx: clinical and imaging findings.

INTRODUCTION: Squamous cell carcinoma is the most common laryngeal neoplasm and accounts for approximately 95% of all malignant neoplams of the larynx. However, various benign and malignant tumors and inflammatory diseases may affect the larynx. OBJECTIVE: The purpose of this study is to analyze the clinical and imaging findings of non-squamous cell neoplasms and inflammatory diseases of the larynx. METHODS: This retrospective study was conducted in 18 patients who were diagnosed with non-squamous cell carcinoma lesions of larynx at our institution between 2007-2017. Clinical symptoms, examination findings, imaging characteristics, histopathologic diagnosis and treatment modalities were analyzed. RESULTS: There were 9 malignant lesions (2 chondrosarcoma, 1 neuroendocrine tumor-atipical carcinoid, 1 Natural Killer/T-cell lymphoma, 1 diffuse large B-cell lymphoma, 3 plasmocytoma-multiple myeloma involvement, 1 adenocarcinoma metastasis), 3 benign neoplasms (chondroma, paraganglioma, lipoma), 2 tumor-like lesions (Brown tumor and inflammatory myofibroblastic tumor), 3 inflammatory lesions (Wegener granulomatosis, Behçet's disease and tuberculosis involvements), and 1 vascular malformation. The most common presenting symptom was hoarseness (66.6%). Paraganglioma was seen as hypervascular lesion on computed tomography and magnetic resonance imaging and showed intense tracer uptake on 68Gallium-DOTA-peptide PET/CT. Chondroid matrix calcifications were detected in chondroma and chondrosarcoma-grade 1. In patients with vascular malformation and lipoma, the typical imaging findings made it possible to diagnose. CONCLUSION: Imaging studies may provide clues for diagnosis of non-squamous cell laryngeal lesions. Clinical and imaging findings and previous clinical history should be evaluated together in clinical management of laryngeal lesions.

Percutaneous antegrade ureteral stent placement: single center experience.

PURPOSE: We aimed to present our clinical experience with percutaneous antegrade ureteral stent placement in a single center. METHODS: Electronic records of patients who underwent percutaneous image-guided ureteral stent placement between September 2005 and April 2017 were reviewed. A total of 461 patients (322 males, 139 females; age range, 19-94 years; mean age, 61.4±15 years) were included in the study. Patients were classified into two main groups: those with neoplastic disease and those with non-neoplastic disease. Failure was defined as persistence of high level of serum creatinine or an inability to place stents percutaneously. Postprocedural complications were grouped as percutaneous nephrostomy and stent placement related complications. RESULTS: A total of 727 procedures in 461 patients were included in the study: 654 procedures (90%) in 407 patients (88.3%) were in the neoplastic group and 73 procedures (10%) in 54 patients (11.7%) were in the non-neoplastic group. Our technical success rates were 97.7% and 100% and complication rates were 3.1% and 4.1% in neoplastic and non-neoplastic groups, respectively. Seven stents retrievals and 112 balloon dilatations were performed successfully. CONCLUSION: Percutaneous antegrade ureteral stent placement is a safe and effective method for management of ureteral injuries and obstructions due to both malignant and benign causes when the retrograde approach has failed.

Multiparametric MRI fusion-guided prostate biopsy in biopsy naive patients: Preliminary results from 80 patients.

OBJECTIVE: The aim of this prospective study was to evaluate the early results of transrectal prostate biopsies performed under the guidance of multiparametric prostate magnetic resonance imaging (mpMRI) in biopsy naive patients. MATERIAL AND METHODS: Biopsy naive patients who had prostate-specific antigen level 4-10 ng/mL and/or abnormal digital rectal examination findings and provided informed consent were examined using mpMRI. The study included 80 patients with an MRI-defined lesion with a Prostate Imaging and Reporting and Data System (PIRADS) score of ≥3. All mpMRIs were reported by the same uro-radiologist according to PIRADS version 2. An MRI-targeted biopsy was performed by an ultrasonography system with rigid fusion registration software. The first two to five core biopsies per MRI-defined lesions were obtained, and then a standard random 12-core biopsy was performed. Transrectal biopsies were performed under local anesthesia or sedoanalgesia. RESULTS: Of the 80 patients, 29 (36.3%) were found to have cancer using the conventional 12-core biopsy, but only 20 (25%) were found to have prostate cancer using the MRI-targeted prostate biopsy. Combining the two biopsy methods (conventional+MRI-targeted), cancer detection rate increased to 43.8% (35/80 patients). The cancer detection rate using the combined method was statistically higher than that using the conventional biopsy method (p=0.03). Using the conventional biopsy method, 960 core biopsies were collected from 80 patients. Of the 960 core biopsies, 111 (11.6%) were found to be cancer. Further, 101 suspected lesions were detected using mpMRI in 80 patients. In addition, 397 core biopsies were obtained from these lesions. Of the 397 core biopsies, 62 (15.6%) were reported as prostate cancer. The core positivity rate of MR-targeted biopsy was statistically higher than that of conventional biopsy (p=0.04). CONCLUSION: The preliminary results of MRI-targeted prostate biopsy combined with conventional biopsy suggested that the combined biopsy method was crucial in prostate cancer diagnosis especially in patients with prostate cancer suspicion and no biopsy history. However, larger sample prospective studies are needed to validate the effectiveness of MRI-targeted biopsy and combined biopsy methods.

Long-term effect of systemic isotretinoin on female fertility.

BACKGROUND/OBJECTIVE: Acne vulgaris is one of the most common diseases of the youth. Systemic isotretinoin is the only drug which acts on all of the etiopathogenic mechanisms of acne. Isotretinoin has some well-known side effects. Besides these, there is a suspicion whether it affects fertility or not. Previously, we conducted a study about isotretinoin's effect on ovarian reserve which showed deteriorative reserve. In this study, we aimed to evaluate the long-term effects of systemic isotretinoin on female fertility. MATERIALS AND METHODS: Of the 82 female patients who were enrolled in the first study, 79 patients were included in this study. Twelve months after the end of systemic isotretinoin treatment, patients were reevaluated by using the same parameters which include anti-Mullerian hormone (AMH), ovarian volume (OV), antral follicle count (AFC), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, free testosterone and total testosterone. RESULTS: The changes in the mean AMH, OV and AFC were statistically significant between the sixth and eighteenth months (the end of systemic isotretinoin treatment and 12 months treatment free). The mean AMH, OV and AFC values at the beginning and at the 18th month were statistically similar. CONCLUSION: The deteriorative effects of systemic isotretinoin treatment on ovarian reserve, which can be accepted as an indicator of female fertility, diminish in time.

Ultrasonography and contrast-enhanced CT findings of tularemia in the neck.

PURPOSE: We aimed to evaluate the ultrasonography (US) and contrast-enhanced computed tomography (CECT) findings of tularemia in the neck. METHODS: US and CECT findings of 58 patients with serologically proven tularemia were retrospectively evaluated. Forty-eight patients underwent US and 42 patients underwent CECT. Lymph node characteristics and parotid preauricular region involvement were analyzed using US and CECT. In addition, involvement of larynx, oropharynx, and retropharynx; presence of periorbital edema; and neck abscess formation were evaluated using CECT. Fine needle aspiration cytology (FNAC) results of enlarged lymph nodes were analyzed in 29 patients. RESULTS: Hypoechoic pattern, round shape, absence of hilum, and cystic necrosis were seen in most of the lymph nodes especially at level 2 and 3 on US and CECT. Matting was more commonly observed than irregular nodal border on US and CECT. Parotid preauricular region involvement was seen in 20.8% of patients on US. Oropharyngeal, retropharyngeal, laryngeal and parotid preauricular region involvement and periorbital edema were seen in 52.4%, 19.1%, 4.8%, 31%, and 9.5% of tularemia patients, respectively. Neck abscess was found in 59.5% of patients on CECT. Suppurative inflammation was the most common finding of FNAC. CONCLUSION: Tularemia should be considered in the presence of level 2 and 3 lymph nodes with cystic necrosis, matting, absence of calcification, oropharyngeal and retropharyngeal region involvement, and neck abscess, particularly in endemic areas.

An Unusual Case of Laryngeal Paraganglioma in a Patient with Carotid Body Paraganglioma: Multimodality Imaging Findings.

Multiple paragangliomas of the head and neck are rare conditions. Carotid paragangliomas are most common multiple paragangliomas. Laryngeal paragangliomas are very rare neuroendocrine tumors and usually are seen as symptomatic solitary lesions. We present multimodality imaging findings of incidentally detected laryngeal paraganglioma in a woman with synchronous carotid body paraganglioma and positive family history. To the best of our knowledge, this is the first case of laryngeal and carotid body paragangliomas in a patient with positive family history. Radiologists should keep in mind that paragangliomas may occur in various locations as multiple tumors.

Neuro-Behçet's disease mimicking a cranial tumour.

Behçet's disease affects many systems and has been described as a multisystem disorder. In Behçet's disease, neurological involvement is responsible for morbidity and mortality, and can sometimes mimic other neurological disorders. We present a case of neuro-Behçet's disease that mimicked a cranial tumour.

Gossypiboma as a rare cause of abdominal mass.

Gossypiboma is a reaction to a foreign body/object left accidentally inside a patient as a consequence of surgery. This phenomenon may be overlooked due to its rarity or under-reported due to possible repercussions. We report an intra-abdominal gossypiboma that was misdiagnosed on ultrasound, and discuss its radiological findings.
