Multimodality imaging features of Canal-of-Nuck hydrocele in adults.

Canal of Nuck abnormalities are common in pediatric population but may rarely present in adults. Hydrocele of the Canal of Nuck is the most common presentation in adult population. These may be symptomatic or found incidentally on imaging. We review the embryology and present imaging features of Canal of Nuck hydroceles in this case-based review article, and highlight the features on various imaging modalities, such as ultrasound, CT (Computed Tomography), MRI (Magnetic Resonance Imaging) and PET (Positron Emission Tomography). Radiologists should be aware of these findings in their practice and be able to recognize these congenital abnormalities.

Intussusception in a child with COVID-19 in the USA.

COVID-19, caused by the novel coronavirus strain SARS-CoV-2 that emerged in late 2019, has resulted in a global pandemic. COVID-19 was initially believed to occur less frequently in children with relatively mild disease. However, severe disease and varied presentations have been reported in infected children, one of such being intussusception. There have only been three reported cases of intussusception in the pediatric population infected with COVID-19. In this paper, we will discuss the management and treatment of a novel fourth case of COVID-19-associated intussusception. This case is the first reported in the USA and suggests that COVID-19 may be implicated in the development of intussusception. Pediatricians should consider the possibility of intussusception when a child with COVID-19 presents with abdominal pain.

Clinical spectrum of Dyke-Davidoff-Masson syndrome in the adult: an atypical presentation and review of literature.

Dyke-Davidoff-Masson Syndrome (DDMS) is a rare condition usually diagnosed in paediatric patients with clinical features of hemiparesis, seizures, mental retardation and contralateral cerebral hemiatrophy on neuroimaging. This report follows the case of a 22-year-old man presenting with seizures and hemiatrophy and hemiparesis. On review of cases the most common neuroimaging findings were cerebral hemiatrophy (100%) followed by hemicalvarial thickening (71.4%) and hyperpneumatisation of sinuses (71.4%). Apart from our patient, all nine cases with data on epilepsy control had drug-resistant epilepsy. The onset of seizures in adulthood, block vertebra, short stature, absence of mental retardation and well-controlled epilepsy on monotherapy makes our case exceptional-even bringing to mind the possibility of a DDMS variant. This report exhaustively reviews the wide range of clinical and radiological manifestations of DDMS in the adult, thereby adding to the literature on an unusual syndrome that causes significant neurological morbidity.
