The goal of this research was to define the diagnostic precision of CT signs to distinguish malignant ascites from cirrhotic ascites. Ascitic fluid cytology was kept as the gold standard.
Study designThis research was a prospective cross-sectional study.
Objective: To compare the diagnostic accuracy of Computed Tomography and Ultrasonography in differentiating trans-dative and exudative pleural effusion.
Study Design: Cross-sectional study.
Place and Duration of Study: Radiology Department of Pakistan Institute of Medical Sciences, Islamabad Pakistan, from Jul to Oct 2021.
Methodology: Patients suffering (n=80) from pleural effusion were involved, and all were assessed with ultrasound and computed Tomography along with diagnostic thoracocentesis. In addition, we investigated pleural thickening, pleural nodules, and loculations along with the USG signs and Computed Tomography attenuation values to detect transudate and exudate in individuals suffering from pleural effusion.
Results: Participants had a mean age of 36.20±6.67 years, ranging from 25 to 49 years. Out of 80 patients, 50(62.5 %) were males, and 30(37.5%) were females. Of the eighty patients with pleural effusion, 29 were transudative 36(25%), and 51 were exudative 63(75%). Overall, USG showed better results for loculations, while CT showed better results for pleural thickeningand nodules.
Conclusion: Attenuation values of Computed Tomography play an essential role in differentiating the type of pleural effusion. In addition, ultrasound is a supporting non-invasive imaging modality that helps define the characteristics of pleural effusion.
Background:
Klippel–Trénaunay-Syndrome (KTS) is characterized by triad of varicose veins, port wine stain and soft tissue or bony hypertrophy and the diagnosis of KTS can be made if any two of these three features are present. Hemangiomas in various location e.g. skull, brain, epidural and vertebral hemangioma, mediastinal, colonic hemangioma, intraneural/intramuscular hemangiomas are reported with KTS.
Case Presentation:
Benign vascular tumors may rarely develop malignant transformation as Bugarin-Estrada et al reported breast angiosarcoma in a patient diagnosed as Klippel-Trenaunay-Syndrome. We reported a case of a 40-year-old female with known case of Klipple-Trenaunay-Syndrome with left leg varicosities, cutaneous nevus as well as unfortunate development of deep venous thrombosis and markedly enlarged right breast hemangioma. Due to low incidence or lack of early detection of breast hemangioma, its diagnosis is challenging.
Conclusion:
The history of patient and multi-modality imaging utilization can help in early and accurate diagnosis of diseases leading to better prognosis.
In this study, we aimed to assess the diagnostic accuracy of carotid Doppler ultrasound (CDU) in detecting anechoic carotid artery thrombus when compared to CT angiography (CTA) as the gold standard.
Materials and methodsThis prospective comparative study was conducted at the Radiology Department of the Pakistan Institute of Medical Sciences, Islamabad from January 2022 to May 2022. The study enrolled 32 patients who met the inclusion criteria. We evaluated patients admitted to the neurology ward/OPD who were referred to radiology as part of a stroke workup based on their clinical examination and medical history. In all patients, CDU was used to detect free-floating thrombus (FFT)/anechoic thrombus. CTA was used as the gold standard to assess the diagnostic accuracy of CDU.
ResultsThe mean age of the study participants was 45.63 ± 7.05 years (range: 33-59 years). Out of 32 patients, 19 (59.4%) were male and 13 (40.6%) were female. The results of CDU were confirmed by CTA in all patients. The diagnostic accuracy of CDU was 53.12% for detecting FFT. The values for sensitivity (54.55%), specificity (50%), positive predictive value (PPV, 70.59%), and negative predictive value (NPV, 33.33%) were also calculated.
ConclusionDespite the limited sample size, the study concludes that CDU has a diagnostic accuracy of 53%. CTA still remains the gold standard imaging modality for anechoic thrombus if strong clinical suspicion is present.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
