Abstract Background Diagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy. Case summary A patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery. Discussion Using multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.

Introduction. The endonasal mucosal or anatomic pathologies could lead to poor functional results and dissatisfaction after rhinoplasty. Although computed tomography (CT) scan has become an integral part of the diagnostic paradigm for patients with pathologies of the paranasal sinuses, the use of CT scan for preoperative evaluation of patients seeking rhinoplasty is up for debate. Our aim in this study was to compare the efficacy of CT scan in diagnosing nasal pathologies with other evaluating tools in patients undergoing rhinoplasty. Design. In this randomized controlled trial study, 74 consecutive patients seeking cosmetic rhinoplasty referred to otorhinolaryngology clinic were randomly assigned into three groups based on the perioperative evaluation method: the CT group, the nasal endoscopy group, and the control group (anterior rhinoscopy only). Surgical planning was made according to perioperative findings, and the identified endonasal pathologies were corrected during the surgery. The functional and aesthetic outcomes of the rhinoplasty were assessed by Nasal Obstruction Symptom Evaluation (NOSE), Rhinoplasty Outcome Evaluation (ROE), and the Visual Analogue Scale (VAS) tools before surgery and at 12-month follow-up. Results. All outcome measures improved significantly in either group toward one year after rhinoplasty (all with p value <0.05). Subjects in the CT group demonstrated greater improvement in the NOSE, VAS, and ROE compared to other two groups (NOSE: p value = 0.17; VAS: p value = 0.024; ROE: p value = 0.042). Conclusions. According to our study, perioperative CT is associated with greater patients’ satisfaction and quality of life after rhinoplasty compared to either nasal endoscopy or anterior rhinoscopy. A preoperative CT scan may improve the outcomes of rhinoplasty.

Background: Accurate evaluation of ovarian carcinoma is utmost important for effective management. PET/CT is reported to be effective in evaluation of suspected recurrence of ovarian carcinoma. This study aims to assess the accuracy of PET/CT in evaluation of recurrent ovarian cancer among clinically suspected cases with rising tumor marker or suspicious clinic-radiological findings. Patients and methods: This prospective cross-sectional study was conducted at Radiology department of Jinnah Postgraduate Medical Centre Karachi from 22nd April 2019 to 21st April 2020. Patients having age of 40 to 60 years and referred for PET scan with suspected recurrence of ovarian carcinoma were consecutively enrolled. Patients were suspected due to relevant history, clinical findings and initial imaging investigations with elevated CA-125 level. Results of 18FDG PET/CT scan was correlated with the raised tumor findings. The PET/CT scan showing abnormally elevated FDG take-up and higher SUV values than the background activity considered recurrence. Diagnostic accuracy of PET/CT was calculated taking raised tumor level as reference category. Results: Of 65 patients, median age was 50 (43-56) years. The findings showed positive cases in 57 (87.7%) while negative in 8 (12.3%) patients, whereas the findings of tumor marker showed raised tumor marker in 61 (93.8%) patients. Diagnostic accuracy of PET/CT showed sensitivity, specificity, positive predicted value, negative predated value, and overall diagnostic accuracy as 93.44%, 100%, 100%, 50%, and 93.85% respectively. Conclusion: A higher accuracy of PET/CT was observed in the diagnosis of recurrent ovarian cancer among clinically suspected cases, thus helping in devising an appropriate management plan by the treating physician.

Abstract Background and study aims Evaluation of longitudinal tumor extent is indispensable for curative surgical treatment of extrahepatic cholangiocarcinoma. The aim of this study was to evaluate the usefulness and feasibility of cholangioscopic-guided mapping biopsy using a newly developed peroral digital cholangioscope, SpyGlass DS (SpyDS), for preoperative evaluation of extrahepatic cholangiocarcinoma. Patients and methods Thirteen patients (mean age, 75 years; male 10, female 3) with extrahepatic cholangiocarcinoma who underwent cholangioscopic-guided mapping biopsy using SpyDS for preoperative evaluation were included in this study. Successful cholangioscopic-guided mapping biopsy was defined as the acquisition of specimens sufficient for histopathological diagnosis. Results The mean number of biopsies was 5 per patient. The overall success rate for cholangioscopic-guided mapping biopsy was 88 % (59/67). The success rate for cholangioscopic-guided mapping biopsy from the confluence of the right and left hepatic ducts was 89 %, that from the B4 confluence was 93 %, that from the confluence of the right anterior and right posterior segmental ducts was 86 %, that from the intrapancreatic common bile duct was 67 %, and that from the main lesion was 100 %. The overall diagnostic accuracy of longitudinal tumor extent at the hepatic side, the duodenal side and overall by cholangioscopic findings and mapping biopsy, was 88 % (7/8), 88 % (7/8) and 88 % (7/8), respectively. Assessment according to location of the main lesion revealed that diagnostic accuracy in the patients with distal bile duct carcinoma was 100 % (5/5) and that in patients with perihilar bile duct carcinoma was 66 % (2/3). Complications after the procedure did not occur in any patients. Conclusions Cholangioscopic-guided mapping biopsy using SpyDS is thought to be feasible for preoperative evaluation of extrahepatic cholangiocarcinoma.

Abstract Objectives: To evaluate the diagnostic accuracy of contrast enhanced CT scan to detect cervical nodal metastasis in oral cavity squamous cell carcinoma keeping final histopathology as gold standard. Methods: Cross sectional study conducted from 1st January 2015 - 31st October 2016. All patients undergoing surgery who had their CT scans done at our centre were included in the study. Diagnostic accuracy of CT scans was calculated using final histopathology as gold standard. All CT scan were reviewed by consultant radiologist. Results: Total 100 patients were reviewed, 70% were female, 55% had buccal and 32% had tongue cancer. 11 cases of T1, 20 cases of T2 , 4 cases of T3 and 21 cases of T4 stages were staged similarly by CT scan and histopathology, the kappa value of38.8%, p value <0.01. 6 cases of N1, 1 case of N2a , 9 cases of N2b, 3 cases of N2c, 1 case of N3 and 29 cases of N0 stages were staged similarly by CT scan and histopathology, with kappa value of 28.1%, p value of  <0.01. Sensitivity, specificity, positive predictive value, negative predictive value and overall diagnostic accuracy were 83%,61%,70.9%,76.3% and 73% respectively. Conclusion: CT scan is useful for preoperative staging of oral cavity squamous cell carcinoma with an overall diagnostic accuracy of 73%, currently there are no superior diagnostic modalities. However, Due to low specificity and negative predictive value elective neck dissection should still be done in a negative CT scan for cervical lymph node metastases. Keywords: Oral Cavity,
