A Rare Cause of Walking Disorder in Childhood.

Guillain-Barre Syndrome is a rare cause of a walking disorder during childhood. MRI is a key role for diagnosis.

[Ruptured dermoid cyst].

We report the case of a 28-year-old male admitted to the emergency department for generalized seizure. A brain computed tomography (CT) revealed a ruptured dermoid cyst of the supra-tentorial stage (multiple drop-shaped fat structures were found in the subarachnoid space, basal cisterns and in ventricular system). An additional magnetic resonance imaging (MRI) was conducted to confirm the CT findings.

[Cytotoxic lesion of the corpus callosum (CLOCC) in a context of viral meningitis].

We report the case of a young patient of 16 years admitted in the emergency department for headache, nausea and vomiting, of brutal installation. After clinico-biological confrontation, the diagnosis of viral meningitis (aseptic) was made. During the initial assessment several complementary examinations and various brain imaging exams (CT, MRI) were performed in the course of the treatment, showing a focal lesion of the splenium of the corpus callosum, with transient aspect and spontaneously resolving during iterative control.

[An unexpected finding in a 14-year-old girl].

A 14-year-old girl was admitted to the Emergency department for abdominal pain. An abdominal mass of 7-8 cm was detected and surgically resected. At anatomopathology a solid pseudopapillary neoplasm of the pancreas was observed.

[Esthesioneuroblastoma: a case report and literature review].

Esthesioneuroblastoma (ENB) or olfactive neuroblastoma is a rare cancer arising from the neuroepithelium of the olfactory epithelium of the nasal cavity. Sinusal, orbital and intracranial expansions are common. The anatomopathological diagnosis will frequently require immuno-histochemical tests and sometimes electron-microscopy as well as genetic testing.

[Clinical case of the month. Computerized tomographic diagnosis of hematoma of the rectus abdominis muscle].

The development of an acute abdominal pain and of a palpable mass following a muscular strain, such as after coughing or sneezing, are features higly suggestive of an abdominal wall hematoma in the patient with predisposing factors. The diagnosis is often difficult since the condition mimics the clinical features of other abdominal pathologies. The diagnostic accuracy has significantly improved however after the advent of ultrasonogarphy and of computed tomography.

Spontaneous tracheal rupture: a case report.

We report the case of a spontaneous posterior tracheal wall rupture following a cough. A 67-year-old woman with a history of longstanding treatment with corticosteroids (8 years) for Giant Cell Arteritis had general anesthesia for cataract removal. Surgery and anesthesia were uneventful.

Duplex ultrasound as first-line screening test for patients suspected of renal artery stenosis: prospective evaluation in high-risk group.

Our objective was to assess how far the progress in ultrasound devices has increased feasibility and accuracy of Duplex ultrasound (DUS) for the diagnosis of renal artery stenosis (RAS), in a population with high prevalence of atherosclerotic renovascular lesions. Ninety-one hypertensive patients with atherosclerotic disease were prospectively evaluated by both DUS and digital subtraction angiography (DSA) of the renal arteries. Only proximal criteria (peak systolic velocity >180 mm/s or renal-to-aortic ratio >3.

[Carotid endarterectomy without arteriography: only dedicated to urgent procedures?].

Duplex examination is presently established as a safe non-invasive and accurate method of evaluating patients with extracranial cerebrovascular disease which usually provides complete information about the extent of carotid artery narrowing Arteriography, in this indication, is an invasive procedure with a total complication rate of 3-4% with 1% of permanent stroke. If it is currently accepted that in emergency conditions (ictus ingravescens, pre-occlusive plaque) or if iodinated contrast media are contraindicated, thrombendarteriectomy can be performed without arteriography it could be extended to most cases. The authors stress the criteria to increase the number of those patients, summarize the pre-requisites to achieve this goal, and comment on the future alternative position of MRA.
