(2016) Ergenoglu, Ahmet Mete; Sahin, Cagdas; Simsek, Deniz; Akdemir, Ali; Yeniel, Ahmet Ozgur; Yerli, Hasan; Sendag, Fatih; https://orcid.org/0000-0003-2463-1758; 26699099; AAK-9572-2021
Objective: To determine and compare the diagnostic accuracy of 3-dimensional ultrasound (3D US) and magnetic resonance imagining (MRI) in patients with surgically diagnosed Mullerian duct anomaly (MDA). Study design: Charts of patients with MDA were retrospectively evaluated. Patients who underwent both laparoscopic and hysteroscopic surgery and had 3D US and MRI examinations were included in the study. The diagnoses achieved via 3D US and MRI were compared with the surgical diagnoses to determine the diagnostic accuracy of these imagining techniques. Results: Twenty-nine patients were included in the study. Three-dimensional ultrasound detected 28 out of 29 (96%) patients correctly. Only one patient was diagnosed with a uterine septum instead of uterine arcuatus. Magnetic resonance imaging detected 23 out of 29 patients correctly (79%). The Kappa indexes of the 3D US and MRI were 0.896 and 0.592, respectively. Conclusion: Our results indicate that 3D US has a higher diagnostic accuracy level than MRI in evaluating MDA, especially when used in experienced hands. However, additional, well-designed studies are needed to better compare the diagnostic accuracy of the 3D US and MRI. Crown Copyright (C) 2015 Published by Elsevier Ireland Ltd. All rights reserved.
Diagnostic Accuracy of Axillary Ultrasound in Early-Stage Breast Cancer
(2019) Yilmaz, Tugba Han; Yerli, Hasan; Arslan, Baha; Erol, Varlik; Gulay, Huseyin
Sentinel lymph node biopsy is the standard application for evaluating the axilla in patients with breast cancer. The Z0011 trial conducted by The American College of Surgeons Oncology Group (ACOSOG) revealed that axillary dissection may be redundant in selected patients with positive sentinel node. This raises questions regarding the application of this result to ultrasound-positive patients. This research therefore aimed to evaluate how accurate an ultrasound scan is for axillary node status in early-stage breast carcinoma. The study included 156 newly diagnosed clinical T1-T2, N0 breast cancer patients attending our breast clinic between January 2010 and February 2016. Sentinel lymph node biopsy and axillary lymph node clearance in the presence of sentinel lymph node metastasis was performed on all the breast cancer patients. Axillary ultrasound reports were reviewed retrospectively and the results compared with surgical pathology results. The sensitivity and specificity of axillary ultrasound for detecting axillary lymph node disease was 69.2% and 98%, respectively, with a negative predictive value of 86.4% and positive predictive value of 94.7%. Given the high sensitivity and specificity, and high positive predictive value and negative predictive value demonstrated in the present study, axillary ultrasound represents a potential alternative to sentinel lymph node biopsy for staging of the axilla in early breast cancer. Subsequent trials (SOUND) comparing axillary ultrasound alone with sentinel lymph node biopsy in early breast cancer patients will provide additional information about the subject.
Dynamic Sonography and CT Findings of Unilateral Submandibular Gland Agenesis Associated with Herniated Hypertrophic Sublingual Gland
(2014) Yerli, Hasan; https://orcid.org/0000-0003-2463-1758; 23893549; AAK-9572-2021
Congenital agenesis of the submandibular gland is uncommon. We report dynamic sonography and CT findings of the unilateral submandibular gland agenesis associated with herniated hypertrophic sublingual gland tissue through the mylohyoid gap. The dynamic sonography examination applied at rest and during the modified Valsalva maneuver demonstrated hypertrophied sublingual gland prolapsing to the anterior part through the mylohyoid gap. This may be the first reported case describing dynamic sonography findings of this entity. CT confirmed the agenesis of the left submandibular gland and compensatory hypertrophy of the ipsilateral sublingual gland. (c) 2013 Wiley Periodicals, Inc. J Clin Ultrasound 42:176-179, 2014
Idiopathic Bilateral Bloody Tearing
(2015) Beyazyildiz, Emrullah; Ozdamar, Yasemin; Beyazyildiz, Ozlem; Yerli, Hasan; 25685572
Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI) of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.
One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis
(2016) Aydin, Elcin; Yerli, Hasan; Avci, Tevfik; Yilmaz, Tugbahan; Gulay, Huseyin; 27308082
Background: Jejunal diverticulitis is one of the rare causes of acute abdomen generally seen in the elderly. Jejunal diverticulosis was defined as the herniation of the mucosa and the submucosa from the inside of the muscular layer of the bowel wall on the mesenteric side of the intestine. Case Report: We presented the intraoperative and pathological findings of a 69-year-old male patient who had presented with complaints about abdominal pain, nausea, and vomiting and been operated upon due to subileus and peritonitis induced by large-sized jejunal diverticulitis, along with his computed tomography (CT) findings. Conclusion: Jejunal diverticulitis is uncommon and may be a disease which might be difficult to diagnose when it develops on the basis of the large-sized diverticula resembling intestinal ansae. To the best of our knowledge, the computed tomography and intraoperative findings of a case in which partial resection is applied to the jejunum due to subileus have not been previously presented in the literature.
Temporal Lobe Parenchyma Herniation into the Transverse Sinus: MRI Findings in a Case
(2016) Aydin, Elcin; Yerli, Hasan; Gezmis, Esin; 0000-0002-1001-6028; 0000-0003-2463-1758; 0000-0003-0907-3647; 30151437; AAE-8301-2021; AAK-9572-2021; AAI-8276-2021
Brain parenchyma herniation into dural venous sinus which is a uncommon entity, can cause dural venous sinus filling and simulate sinus thrombosis and other pathologies. It is isointense to brain parenchyma on all sequences by magnetic resonance imaging, surrounded by a cerebrospinal fluid rim and is seen to be contiguous with brain tissue on images. We report a rare case with spontaneous occult herniation of temporal lobe tissue into the left transverse sinus that may associated with headache.
