Phalangeal microgeodic syndrome: a paediatric case series.

We present the clinical and radiological characteristics of phalangeal microgeodic syndrome in a cluster of five children during the second peak of COVID-19 pandemic in the UK. Each child presented with phalangeal swelling and erythema, prompting a comprehensive multi-disciplinary team review to analyse the clinical presentation, blood test results and imaging. The cohort's average age was 14.

Phalangeal microgeodic syndrome, COVID-19, and antinuclear antibodies in a child: A case report.

Phalangeal microgeodic syndrome (PMS) is a rare rheumatological disease affecting children strongly associated with cold weather. It is considered to be benign and self-limiting, with most cases resolving in warmer months, and no studies have investigated its association to autoantibodies or viral infection. In this peculiar case, a 12-year-old child with the previous COVID-19 infection developed PMS that did not improve in the warm weather and, subsequently, Raynaud's phenomenon and facial rash.

Chronic esophageal dissection: Delayed diagnosis in a 15-year-old male.

Esophageal dissection is a rare condition, characterized by disruption of the submucosa from the muscular layer of the esophageal wall. It is commonly iatrogenic in etiology and patients typically present with acute onset dysphagia, odynophagia, and retrosternal pain. The condition can be diagnosed endoscopically; however, contrast swallow studies either with CT or fluoroscopy carry less risk and are the imaging investigations of choice for this condition.

A case of spinal melorheostosis.

Melorheostosis is a rare bone dysplasia of unknown etiology with an incidence of 0.9 cases per million. It typically affects the upper or lower limbs and can cause severe deformity and functional impairment.

Characteristics of Chest CT Images in Patients With COVID-19 Pneumonia in London, UK.

Background and objective Novel coronavirus 2019 (COVID-19) outbreak was first reported in Wuhan, Hubei Province in China in December 2019; it has then spread quickly and exponentially beyond the Chinese borders and is now regarded as a global pandemic. We aimed to evaluate the chest CT radiological characteristics and lesion distribution patterns in patients of COVID-19 pneumonia in London, UK. Methods We performed a retrospective study and reviewed data of patients with clinically suspected COVID-19 who underwent chest CT between February 1 and May 5, 2020.

Positive Chest CT Features in Patients With COVID-19 Pneumonia and Negative Real-Time Polymerase Chain Reaction Test.

Objectives Clinically suspicious novel coronavirus (COVID-19) lung pneumonia can be observed typically on computed tomography (CT) chest scans even in patients with a negative real-time polymerase chain reaction (RT-PCR) test. The purpose of the study was to describe the CT imaging findings of five patients with negative RT-PCR results on initial and repeated testing but a high radiological suspicion of COVID-19 pneumonia. Methods Out of 19 clinically and/or radiologically diagnosed COVID-19 patients from our institution, five patients were selected for our study who had typical findings of COVID-19 on CT scan despite two negative RT-PCR results.

A case of triorchidism.

We present the case of an adolescent male who presented with a painless left scrotal lump. Investigations revealed a diagnosis of a supernumerary testicle or polyorchidism. In this case report we discuss the imaging findings of polyorchidism on different modalities.

Erdheim-Chester Disease: A Case Report and Review of the Literature.

Erdheim-Chester disease (ECD) is a rare form of non-Langerhans' cell histiocytosis characterized by xanthogranulomatous infiltration of foamy histiocytes surrounded by fibrosis. ECD may be asymptomatic or present as a multi-systemic disease with life-threatening manifestations, most commonly involving the skeletal system. Immunohistochemical staining demonstrates cells that are CD68+, CD1a-, and S100- with an absence of Birbeck granules.

Maceration determines diagnostic yield of fetal and neonatal whole body post-mortem ultrasound.

Objectives: To determine factors in nondiagnostic fetal and neonatal post-mortem ultrasound (PMUS) examinations.

Methods: All fetal and neonatal PMUS examinations were included over a 5-year study period (2014-2019). Nondiagnostic image quality by body parts (brain, spine, thorax, cardiac, and abdomen) was recorded and correlated with patient variables.

Breast Hemangioma: MR Appearance with Histopathological Correlation.

Breast hemangioma is a rare tumor and when small, it may be difficult to diagnose using conventional imaging techniques. In this report the MR appearance is described with histopathological correlation.
