    Gossypiboma/textiloma mimicking as tumour recurrence
    (2014-06-01T00:00:00Z) ATAY, Musa; AHMAD, Issam Cheikh; Bilgin, MEHMET; KOCAKOÇ, Ercan; BİLGİN, MEHMET
    A surgical sponge accidentally left in a surgical wound, called a textiloma or gossypiboma, is underreported in literature due to medicolegal consequences. Abdominal textiloma may be asymptomatic or present serious gastrointestinal complications such as bowel obstruction, perforation or fistula formation because of misdiagnosis. It may mimic abscess formation in early stage or soft-tissue masses in chronic stage. If there is an intraabdominal abscess resistant to catheter drainage in the postoperative period or an intraabdominal soft tissue mass with a history of previous surgery, textiloma should be included in the differential diagnosis.Whirl-like spongiform pattern especially on CT, well-defined border and fibrous capsule especially on MRI can help in the diagnosis of textiloma. We describe a case of intraabdominal textiloma mimicking abscess and soft tissue tumour on CT and MRI examination.

    Diffusion Tensor Imaging Can Discriminate the Primary Cell Type of Intracranial Metastases for Patients with Lung Cancer.

    Purpose: Histopathological differentiation of primary lung cancer is clinically important. We aimed to investigate whether diffusion tensor imaging (DTI) parameters of metastatic brain lesions could predict the histopathological types of the primary lung cancer. Methods: In total, 53 patients with 98 solid metastatic brain lesions of lung cancer were included. Lung tumors were subgrouped as non-small cell carcinoma (NSCLC) (n = 34) and small cell carcinoma (SCLC) (n = 19). Apparent diffusion coefficient (ADC) and Fractional anisotropy (FA) values were calculated from solid enhanced part of the brain metastases. The association between FA and ADC values and histopathological subtype of the primary tumor was investigated. Results: The mean ADC and FA values obtained from the solid part of the brain metastases of SCLC were significantly lower than the NSCLC metastases (P < 0.001 and P = 0.003, respectively). ROC curve analysis showed diagnostic performance for mean ADC values (AUC=0.889, P = < 0.001) and FA values (AUC = 0.677, P = 0.002). Cut-off value of > 0.909 × 10-3 mm2/s for mean ADC (Sensitivity = 80.3, Specificity = 83.8, PPV = 89.1, NPV = 72.1) and > 0.139 for FA values (Sensitivity = 80.3, Specificity = 54.1, PPV = 74.2, NPV= 62.5) revealed in differentiating NSCLC from NSCLC. Conclusion: DTI parameters of brain metastasis can discriminate SCLC and NSCLC. ADC and FA values of metastatic brain lesions due to the lung cancer may be an important tool to differentiate histopathological subgroups. DTI may guide clinicians for the management of intracranial metastatic lesions of lung cancer.

    Severe Valvular Regurgitation: An Unexpected Complication During Transapical Aortic Valve Implantation Treated Successfully with the -Valve-in-Valve- Procedure
    (2012-12-01T00:00:00Z) BURGAZLI, Kamil Mehmet; KAVUKCU, Ethem; CHASAN, Ridvan; Bilgin, MEHMET; ERDOGAN, Ali; BİLGİN, MEHMET
    Severe symptomatic aortic stenosis (AS) in a multimorbid 77 year old female was treated with transapical aortic valve implantation with a 23 mm Edwards Sapien valve. Severe valvular regurgitation following implantation, probably due to structural valve failure, was treated successfully with a second valve-in-valve implantation. During a follow-up time of 2,5 years no further problems occurred.

    Introduction and objective: Colonic wall thickening is a common condition in a number of benignant and malignant diseases. This study investigated the accuracy of radiological diagnoses in patients diagnosed with colonic wall thickening using multislice CT (MDCT). Materials and method: Files of patients with colonic wall thickening diagnosed with 64-slice MDCT were reviewed retrospectively. The colonoscopy results of these patients were grouped under neoplastic process (cancer and adenomatous polyp), inflammatory bowel disease (IBD), diverticulitis and other etiology (nonspecific events, ischemic colitis, solitary rectal ulcer, external compression, secondary to volvulus and radiotherapy), and the results were statistically evaluated. p values < 0.05 were considered statistically significant. Results: The study was performed on 505 files (290 males [57.4%], 215 females [42.6%], mean age: 49.15 ± 18.4 years). CT and colonoscopic diagnoses were reviewed and the following CT to colonoscopy ratios was observed: neoplastic process: 44.4% vs. 40.2%; IBD: 42.4% vs. 42.4%; diverticulitis: 4% vs. 4.2%; other etiology: 9.3% vs. 3.2%. Colonoscopy failed to identify pathology in 9.9% of the patients. The sensitivity, specificity, PPV, NPV and accuracy of CT were 95.6%, 90.4%, 87.1%, 96.8% and 92.4%, respectively, in detecting neoplastic processes; 97.2%, 97.9%, 97.2%, 97.9% and 97.6%, respectively, in detecting IBD; 90.5%, 99.8%, 95%, 99.6% and 99.4%, respectively, in detecting diverticulitis, and 50%, 96,7%, 62.5%, 94.6% and 92%, respectively, in detecting other etiology. Conclusion: While, accuracy of 64 slice-CT in diagnosing colonic wall thickenings secondary especially to neoplastic processes, IBD and diverticulitis was significantly higher, but differential diagnosis is challenging in pathologies due to other etiologies.

    T2 Signal Intensity of the Trigeminal Nerve: A New Diagnostic Criteria for Trigeminal Neuralgia?
    (2018-01-01) Hatiboglu, Mustafa A.; KAYA, Ozlem K.; Alkan, ALPAY; Timocin, GİZEM; BADUR, Bahar A.; Bilgin, MEHMET; ALKAN, ALPAY; HATİBOĞLU, MUSTAFA AZİZ; TİMOÇİN, GİZEM; BİLGİN, MEHMET
    Objectives: The objectives of this study were to: 1) compare the size and T2 signal intensity of the trigeminal nerves on the symptomatic side and asymptomatic side of the patients with idiopathic trigeminal neuralgia and to correlate these morphological findings with each other in order to assess whether Magnetic Resonance Imaging (MRI) can provide evidence of microstructural changes in the affected trigeminal nerve that could be potential imaging markers for diagnosis and monitoring trigeminal neuralgia 2) correlate these data with the pain score of the patients in order to search a quantitative evaluation method of the pain in patients with Trigeminal Neuralgia (TN).
