Ultrasound Features

Mature cystic teratoma often referred to as dermoid cysts have been diagnosed using all imaging modalities. Dermoid cysts present various and complex ultrasonographic aspects. At times diagnosis may be difficult and lead to confusion due to its complex solid and cystic nature. The specificity for diagnosis of fat and calcification makes computed tomography (CT) scan the modality of choice. But CT scan is high technique equipment, expensive and may not be affordable or available at all places. Advances in the quality of USG machines, better experiences of ultrasound operators and thorough analysis of all ultrasound features that characterise dermoid cysts have resulted in an increased accuracy of exact ultrasonographic diagnosis of dermoid cysts in the vast majority of the cases and now used as the first preoperative work-up method of choice for the assessment of adnexal masses in clinical practices.

Background: Adnexal masses originating from gynaecologic and nongynecologic sources may be benign or malignant. The objective of this study was to describe multi-detector computed tomography features of benign adnexal masses for diagnostic accuracy and disease understanding.Methods: Study retrospectively evaluates the multidetector computed tomography features of benign adnexal mass lesions, which were referred for MDCT examination with a primary diagnosis of adnexal masses on clinical or USG. Patients who underwent MDCT and subsequently underwent surgery and proved to benign adnexal mass lesion on histopathological examination were included in this study.Results: Forty five percent benign adnexal mass were in the age group of 36-50 years followed by 32.7% in the age group of 21-35 years. Common presenting symptoms of benign adnexal masses were pain abdomen or pelvic pain (65.5%) followed by mass abdomen (42%) while in one fourth of the patients it was asymptomatic and detected as incidental finding. Pathologic diagnosis of most common benign adnexal mass detected were serous cyst adenoma (54.5%), followed by mature cystic teratoma (18.2%), mucinous cyst adenoma (14.5%) and par ovarian cyst (9.1%). Benign ovarian mass had a characteristic CT appearance of cystic lesion (83.6%), unilocular (65.5%) with regular/well defined and thin wall (83.6%) with occasional septations (21.8%) and papillary projections (14.5%). Ascitis (5.5%) was an uncommon finding of a benign adnexal mass lesion. Computed tomography was most accurate to characterize mature cystic teratoma with a typical cystic lesion having fat deposition and calcifications.  Serous cyst adenoma had a CT appearance of thin walled cyst mass with no septations or solid component. Mucinous cyst adenoma ovary had a characteristic multilocular cystic lesion with different fluid attenuation and thin septations.  Endometrioma had a variable CT appearance with uni or multilocular cystic lesion and hyperdense lesion with focal calcifications.Conclusions: Multi detector computed tomography may provide accurate and valuable diagnostic information about benign nature of an adnexal mass lesion.

AbstractBackgroundThe outbreak of the coronavirus disease 2019 (COVID-19) has had a massive impact on the whole world. Computed tomography (CT) has been widely used in the diagnosis of this novel pneumonia. This study aims to understand the role of CT for the diagnosis and the main imaging manifestations of patients with COVID-19.MethodsWe conducted a rapid review and meta-analysis on studies about the use of chest CT for the diagnosis of COVID-19. We comprehensively searched databases and preprint servers on chest CT for patients with COVID-19 between 1 January 2020 and 31 March 2020. The primary outcome was the sensitivity of chest CT imaging. We also conducted subgroup analyses and evaluated the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.ResultsA total of 104 studies with 5694 patients were included. Using RT-PCR results as reference, a meta-analysis based on 64 studies estimated the sensitivity of chest CT imaging in COVID-19 was 99% (95% CI, 0.97-1.00). If case reports were excluded, the sensitivity in case series was 96% (95% CI, 0.93-0.99). The sensitivity of CT scan in confirmed patients under 18 years old was only 66% (95% CI, 0.11-1.00). The most common imaging manifestation was ground-glass opacities (GGO) which was found in 75% (95% CI, 0.68-0.82) of the patients. The pooled probability of bilateral involvement was 84% (95% CI, 0.81-0.88). The most commonly involved lobes were the right lower lobe (84%, 95% CI, 0.78-0.90) and left lower lobe (81%, 95% CI, 0.74-0.87). The quality of evidence was low across all outcomes.ConclusionsIn conclusion, this meta-analysis indicated that chest CT scan had a high sensitivity in diagnosis of patients with COVID-19. Therefore, CT can potentially be used to assist in the diagnosis of COVID-19.
