Abstract Acute appendicitis is the commonest nonobstetric cause of acute abdomen in pregnancy. Appendiceal diverticulitis, albeit very rare, warrants special attention owing to it's often insidious ...presentation and increased risk of perforation coupled with difficulty in diagnosing appendicitis in pregnancy. We describe a case of appendiceal diverticulitis in pregnancy diagnosed with ultrasound and MRI and review the imaging manifestations of this entity. To the best of our knowledge, this is the second case of appendiceal diverticulitis in pregnancy reported so far and the first report describing the MRI findings in appendiceal diverticulitis.
Abstract Polyorchidism is a rare urogenital developmental anomaly defined as the presence of more than two testes. Triorchidism is the most common type of polyorchidism and presents with two testes ...on one side (usually the left) and one testis on the other side. We report a rare case of polyorchidism with three homolateral testes on the right side and absent testis on the left side. Magnetic resonance imaging was used in the present case to investigate the cause for infertility and to confirm this rare diagnosis without surgical exploration.
This article presents an updated review of cystic renal mass imaging. Most cystic renal masses encountered incidentally are benign and can be diagnosed confidently on imaging and require no ...follow-up. Hyperattenuating masses discovered at unenhanced or single-phase enhanced computed tomography (CT) measuring between 20–70 HU are indeterminate and can be further investigated first by using ultrasound and, then with multi-phase CT or magnetic resonance imaging (MRI); as the majority represent haemorrhagic/proteinaceous cysts (HPCs). Dual-energy CT may improve differentiation between HPCs and masses by suppressing unwanted pseudo-enhancement observed with conventional CT. HPCs can be diagnosed confidently when measuring >70 HU at unenhanced CT or showing markedly increased signal on T1-weighted imaging. Although the Bosniak criteria remains the reference standard for diagnosis and classification of cystic renal masses, histopathological classification and current management has evolved: multilocular cystic renal cell carcinoma (RCC) has been reclassified as a cystic renal neoplasm of low malignant potential, few Bosniak 2F cystic masses progress radiologically during follow-up; RCC with predominantly cystic components are less aggressive than solid RCC; and Bosniak III cystic masses behave non-aggressively. These advances have led to an increase in non-radical management or surveillance of cystic renal masses including Bosniak 3 lesions. Tubulocystic RCC is a newly described entity with distinct imaging characteristics, resembling a pancreatic serous microcystadenoma. Other benign cystic masses including: mixed epithelial stromal tumours (MEST) are now considered in the spectrum of cystic nephroma and angiomyolipoma (AML) with epithelial cysts (AMLEC) resemble a fat-poor AML with cystic components.
