In this review, we investigated the diagnostic value of the sonographic "whirlpool sign" in identifying ovarian torsion. This was done by performing a search in PubMed, Scopus, Embase, Web of Science, CINAHL, and Google scholar. Additional search for the grey literature was made in EThOS.bl.uk, explore.bl.uk, opengrey.eu, greylit.org, and clinicaltrials.org. A total of eight studies were included in this meta-analysis. Sensitivity and specificity of whirlpool sign were extracted from the studies and computed into the Metadisc statistical software for pooled analysis. The whirlpool sign showed a high sensitivity and specificity for the diagnosis of ovarian torsion.

Placenta accreta spectrum is a pregnancy complication associated with severe morbidity and maternal mortality especially when not suspected antenatally and appropriate management instigated. Women in resource-limited settings are more likely to face adverse outcomes due to logistic, technical, and resource inadequacies. Accurate prenatal imaging is an important step in ensuring good outcomes because it allows adequate preparation and an appropriate management approach. This article provides a simple three-step approach aimed at guiding clinicians and sonographers with minimal experience in placental accreta spectrum through risk stratification and basic prenatal screening for this condition both with and without Doppler ultrasound.

Uterine scar dehiscence with underlying placenta is often misdiagnosed as placenta accreta spectrum both prenatally and intraoperatively due to the absence of myometrial tissue in the area. Misdiagnosis generates obstetric anxiety and results in overtreatment which carries a risk of iatrogenic injury. We present a case of the antenatal diagnosis of uterine dehiscence in a 36-year-old woman with a history of two caesarean deliveries and a low-lying placenta. We further describe the sonographic features useful for differentiating this condition from placenta accreta spectrum in instances where the placenta lies under an area of full thickness uterine scar dehiscence.

Vasa previa is characterised by unprotected umbilical vessels that are crossing the internal cervical os or lying close to it. When vasa previa is not detected during antenatal period, the perinatal outcome could be grievous. Ultrasound is the modality of choice in detection of vasa previa. Despite the increasing availability of ultrasound in modern times, its use in diagnosing vasa previa still remain very low in Africa. We present the sonographic findings and perinatal outcomes of three cases of vasa previa which were detected antenatally within a period of nine months in an African setting.

Introduction: Cavernous transformation of the portal vein, although a hepatic condition, may manifest with clinical features similar to those in patients with gastrointestinal pathologies. Particularly in young patients with no prior history of alcoholism or hepatic pathology, the diagnosis of cavernous transformation of the portal vein may be missed in an emergency setting where patients’ reported symptoms may be mimicking those associated with bleeding peptic ulcer or other gastrointestinal pathologies. Case Report: We present a case of a 22-year-old male with no prior history of hepatic or pancreatic pathology who presented to the emergency room with some episodes of haematemesis, melena and slight dizziness, in whom a cavernous transformation of the portal vein was identified by abdominal duplex ultrasonography. Discussion: The clinical diagnosis of cavernous transformation of the portal vein can be challenging and easily missed especially in instances where a patient with no history of chronic alcoholism, liver cirrhosis, hepatoma, pancreatitis or prior abdominal surgery presents to the emergency room with haematemesis and anaemia. Ultrasonography presents as a reliable radiological tool in the diagnosis of rare and unforeseen conditions like cavernous transformation of the portal vein to allow for prompt management and prevention of adverse patients’ outcomes. Conclusion: Abdominal duplex ultrasonography can reliably aid in the prompt diagnosis and management of patients with unforeseen rare hepatic pathologies such as cavernous transformation of the portal vein who present with upper gastrointestinal bleeding.

Objectives: To document the pattern of chest radiographic findings in coronavirus disease 2019 (COVID-19) patients with moderate to severe disease. Design: Retrospective cross-sectional study. Setting: The study site was Komfo Anokye Teaching Hospital (KATH) located at Bantama in Kumasi, the capital town of the Ashanti Region. It is the second largest hospital in the country and the major referral site for Ashanti region and the northern part of the country. The hospital hosts a highly infectious isolation unit (HIIU) for COVID19 patients with moderate to severe infections and receives referred cases from the region and within the hospital. Participants: The study involved 27 patients admitted to the HIIU at KATH with COVID-19 infection who underwent chest X-ray as part of their investigations. Results: The study enrolled 12 males and 15 females. The common comorbidities were hypertension and diabetes. Chest x-ray findings in most of the patients (81.5%) revealed ground-glass opacities while a few of them (18.5%) had lung consolidations without ground-glass opacities. For those with ground-glass opacities, eight (29.6%) had superimposed consolidation. All the participants had positive chest x-ray findings. Conclusion: The chest x-ray findings in the 27 COVID-19 positive patients with moderate to severe disease on admission at the KATH HIIU enrolled in this study showed significant pulmonary abnormalities. The predominant pulmonary abnormalities were bilateral peripheral ground-glass opacities with the lower lung zones being mostly affected.
