A case report of hepatic inflammatory myofibroblastic tumor in a pediatric patient: diagnostic challenges and management strategies.

Purpose: The aim of this study is to present a case of inflammatory myofibroblastic tumor (IMT) of the liver in a 4-year-old girl. We will discuss the diagnostic challenges, the role of the radiologist in differential diagnosis, treatment modalities, and clinical outcomes.

Methods: A case report of a 4-year-old girl with IMT of the liver is presented.

Ultrasound features of cutaneous myiasis: a rare case in a child.

Cutaneous myiasis is an infestation of the skin with larvae of some dipteran species. Among humans, Dermatobia hominis is the most frequently encountered dipteran responsible for cutaneous myiasis. This insect is endemic to tropical and subtropical regions, consequently, individuals travelling from non-endemic areas are most susceptible to infection due to a lack of prior exposure.

Accuracy of point-of-care ultrasound in the diagnosis of acute appendicitis in a pediatric emergency department.

Purpose: To investigate the accuracy of point-of-care ultrasound (PoCUS) in diagnosing acute appendicitis in children; to evaluate the concordance between PoCUS performed by a pediatric emergency physician (PedEm) and ultrasonography (US) performed by a radiologist; to draw a "learning curve."

Methods: We prospectively enrolled children aged 0-14 years old led to the Emergency Department of Regina Margherita Children's Hospital, from January 2021 to June 2021, with suspected acute appendicitis. PoCUS was performed by a single trained PedEm, blindly to the radiologist's scan.

Unresectable Clival Giant Cell Tumor, Tumor Control With Denosumab After Relapse: A Case Report and Systematic Review of the Literature.

Giant cell tumors (GCTs) of the skull base are rare entities. Although considered histologically benign, GCTs are locally aggressive with a high rate of local recurrence. The present case describes a 14-year-old girl with a clival GCT who underwent long-term therapy with denosumab after local relapse.

SHOX deficiency in children with growth impairment: evaluation of known and new auxological and radiological indicators.

Background: The phenotypic features of SHOX deficiency (SHOX-D) are highly variable and can be very mild, especially in young children. The aim of this retrospective study was to evaluate auxological and radiological indicators that could be predictive of SHOX-D in children.

Methods: Molecular analysis of the SHOX gene was performed in 296 subjects with growth impairment or skeletal disproportion, without alternative diagnosis.

Pulmonary nodular lymphoid hyperplasia in pediatric patients with Hodgkin lymphoma.

Pulmonary lymphoid lesions span from benign to other forms of malignant diseases. Among these pulmonary lymphoid lesions, Nodular Lymphoid Hyperplasia (NLH) has an excellent prognosis. The surgical excision of NLH seems to be the only treatment, even if in some cases a spontaneous regression has been reported.

Severe arterial hypertension and hyperandrogenism in a boy: a rare case of catecholamine- and β-HCG-secreting pheochromocytoma.

Background Pheochromocytomas (PCCs) and paragangliomas (PGLs) are known to physicians as the "great mimickers" because of their variable presentation, especially in the pediatric population. Rarely, they co-secrete other hormones. Case presentation An 11-year-old boy presented with severe hypertension (HTN) with cardiac target organ damage.

Pediatric neck masses: how clinical and radiological features can drive diagnosis.

Pediatric neck masses are a common occurrence and often represent a diagnostic challenge. The primary aim of this retrospective study was to evaluate the clinical and radiological features of neck masses in children and how they can drive diagnosis. The secondary aim was to create a diagnostic algorithm based on clinical features.

MRI and 18F-FDG-PET/CT in a rare case of early (precursor) B-lymphoblastic leukaemia with bone involvement as initial manifestation.

A 4-year old girl presenting gait difficulty was referred for spine X-ray and Magnetic Resonance Imaging (MRI). MRI showed several diffuse hypointense signals in sacral and lumbar vertebrae. In order to exclude a possible lymphoproliferative disease a 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) was requested.

Predictivity of Clinical Findings and Doppler Ultrasound in Pediatric Acute Scrotum.

Purpose: To evaluate the role of Doppler ultrasonography (DUS) in diagnosing pediatric testicular torsion (TT), and its diagnostic accuracy, and helping clinicians increase specificity and decrease negative exploration rates.

Materials And Methods: We performed a retrospective study of all consecutive patients with acute testicular symptoms referring to our pediatric emergency department (ED) from January 2010 to December 2013.

Results: We analyzed 1091 patients, with a mean age of 9 years.

Intracranial aspergillosis in children successfully treated with antifungal therapy and surgical intervention.

Invasive aspergillosis is an uncommon but often lethal complication in immunocompromised patients. Despite the progress obtained with new antifungal drugs, intracranial aspergillosis often requires a combined medical and surgical approach. Most cases previously reported in immunocompromised children were fatal.
