Primary obturator-muscle pyomyositis in immunocompetent children.

Purpose: Primary pyomyositis in immunocompetent children in non-tropical regions (countries with temperate climates) is very uncommon. It is rarely found in the intrapelvic muscles, and even more rarely in the obturator muscles. We try to draw attention to the potential occurrence in these conditions.

[Posterior reversible encephalopathy syndrome: 5 chemotherapy related cases].

Posterior reversible encephalopathy syndrome, previously known as Reversible posterior leukoencephalopathy syndrome, is a clinical-radiological condition characterized by headache, altered mental functioning, seizures and visual alterations, with the magnetic resonance imaging showing cerebral edema, predominantly in the white matter with posterior distribution. Multiple clinical conditions can act as triggers. We present five oncology patients, four of them with acute lymphoblastic leukemia, receiving chemotherapy when they presented with this pathology.

Magnetic resonance imaging abnormalities in children with epilepsy.

Background And Purpose: The aim of this study is to analyze the proportional distribution of epilepsy and epileptic syndromes in children and to describe the magnetic resonance imaging (MRI) abnormalities found in these patients.

Methods: Data from 457 children aged 1 month to 15 years at the time of diagnosis of epilepsy were recorded. A routine MRI has been requested in all patients with epilepsy at diagnosis according to a standardized pediatric seizure protocol.

[Ultrasonography for surgical pathology discrimination in acute abdominal pain. Prospective study].

Abdominal ultrasonographic study is a part of the acute abdominal pain diagnosis protocol in our hospital. As an internal quality assessment, we performed a six-month prospective study, including those patients who meet one of these requirements: 1st the reason for attendance being non-traumatic abdominal pain 2nd an abdominal ultrasonography achieved at the hospital. Collected data included: demographic characteristics, presenting sign and symptoms, test results, ultrasonography, final diagnosis and treatment.

Radiological appearance of diaphragmatic mesothelial cysts.

Background: Diaphragmatic mesothelial cysts are congenital lesions that derive from coelomic remnants.

Objective: To describe their radiological appearance on US, CT and MRI.

Materials And Methods: Four children (aged 7-14 years) who underwent surgery and for whom there was pathological confirmation of the diagnosis.
