Ascaris lumbricoides is one of the most common human helminthic diseases worldwide. On ultrasound, it is seen as linear non-shadowing echogenic structures with target appearance in cross section, and the live worm may show writhing movements in real time. On barium meal follow through, it appears as radiolucent tubular filling defects within the bowel lumen. Though not sensitive, direct real-time visualization of Ascaris on ultrasound is quick, non-invasive, and definitive.

Diffusion-weighted MRI in inflammatory renal lesions: all that glitters is not RCC!

To evaluate whether diffusion-weighted MRI (DW-MRI) can distinguish pseudotumours in chronic kidney disease (CKD pseudotumours) from renal-cell-carcinomas (RCCs) (with or without CKD) and whether it offers additional benefit over conventional MRI.

Kimura disease is a rare chronic inflammatory disorder mostly reported in males in second to third decades from south-east Asia. Head and neck is the most commonly involved region. The usual presentation is painless facial swelling with salivary gland involvement and regional lymphadenopathy. The diagnosis can be suspected on imaging but needs to be proven on histopathology. We describe three histopathology proven cases of Kimura disease and emphasize the specific clinic-radiological findings which can help in early identification of the condition and its differentiation from other diseases with similar presentation. Gray scale Ultrasound, contrast-enhanced ultrasound, and contrast-enhanced Magnetic Resonance Imaging (CE-MRI) were done in all patients and Computed Tomography (CT) was done in one. The salient imaging features were ill-defined solid mass in the subcutaneous location of the facial region which was heteroechoic on Gray scale Ultrasound, heterogeneously hyperintense on T2W MRI and without much diffusion restriction. There was involvement of salivary glands with ipsilateral cervical adenopathy. The lesion showed avid contrast enhancement on contrast-enhanced ultrasound and CE-MRI. We also present a systematic literature review of clinico-radiological features in Kimura disease in the head and neck. The articles with histopathologically proven cases and satisfactory description of imaging findings were included and we have compared the findings in our cases with published literature. In addition, we have included examples of radiological mimics of this disease. Certain imaging findings are highly suggestive and can aid in early diagnosis of Kimura disease which helps in early initiation of treatment with better patient prognosis.

The WHO classification of soft tissue tumours categorizes the lesions based on histological differentiation. In the recent fifth edition (2020), many new entities have been introduced, based on their distinct biological behaviour, genetics and morphology. With the recent advances and better understanding of molecular genetics, several novel recurrent genetic alterations have been incorporated in this edition. These may serve as reliable diagnostic and prognostic markers for various soft tissue tumours. Though predominantly a pathologist's game; the radiologists must be aware of the recent updates to contribute towards the optimal diagnosis and management of soft tissue tumours. The imaging features of the new entities have not yet been described but are expected to be explored in the coming years. We hereby present a concise review of the updates in the recent WHO classification of soft tissue tumours. We have tried to emphasize the novel molecular genetics and their surrogate immunohistochemical markers which have brought a paradigm shift in the diagnosis, therapeutics, and prognosis of soft tissue tumours. We also present simplified diagnostic algorithms to characterize soft tissue tumours based on the clinico-radiological features.

Evaluation of perfusion characteristics is the key to characterize vascular anomalies. Contrast-enhanced ultrasound (CEUS) is a radiation-free modality to evaluate this in real-time and can be coupled along with Doppler-ultrasound (US).
