Neurological and orbital complication of acute sinusitis in pediatric patient: A case report.

Sinusitis is a common condition that can lead to various neurological complications due to the spread of infection to the intracranial and orbital regions. Fortunately, the availability of antibiotics has significantly improved the prognosis of sinusitis-associated intracranial complications. As a result, the overall incidence of neurological complications arising from sinusitis remains low.

Lemmel's syndrome due to giant periampullary diverticulum: report of a case.

Lemmel's syndrome is a rare cause of obstructive jaundice in the absence of stones or tumors, commonly due to periampullary duodenal diverticulum (PAD). CT scan with the oral and intravenous administration of iodinated contrast media, was crucial to exclude the presence of stones or tumours, but esophagogastroduodenoscopy (EGD) confirms the diagnosis. We report a case of a 72 -year-old woman affected by Lemmel's syndrome secondary to a giant PAD, suffering from right upper abdominal quadrant pain and pancreaticobiliary disease.

"Split atlas" in a trauma and nontrauma patient: two different case reports for a rare congenital malformation.

Congenital atlas abnormalities are rare and often asymptomatic findings, accidentally detected in trauma and, more rarely, in nontrauma patients. Rachischisis in both anterior and posterior atlas arches, condition defined as ''split atlas," is extremely uncommon and it may well be confused with fracture. Being able to discriminate between these 2 conditions is an essential step in patient care management.

Spontaneous intracranial hypotension: two steroid-responsive cases.

Purpose: Spontaneous intracranial hypotension (SIH) is characterised by orthostatic headache, low cerebrospinal fluid pressure and diffuse pachymeningeal enhancement after intravenous gadolinium contrast administration. Magnetic resonance imaging (MRI) often plays a crucial role for correct diagnosis.

Case Description: We described two similar cases of SIH, whose clinical and imaging features are typical for this pathology.

High b-Value Diffusion MRI to Differentiate Recurrent Tumors from Posttreatment Changes in Head and Neck Squamous Cell Carcinoma: A Single Center Prospective Study.

Recently DW-MR Imaging has shown promising results in distinguishing between recurrent tumors and posttreatment changes in Head and Neck Squamous Cell Carcinoma (HNSSC). Aim of this study was to evaluate the diagnostic performances of DWI at high b-value (b = 2000 s/mm(2)) compared to standard b-value (b = 1000 s/mm(2)) and ADCratio values (ADCratio = ADC2000/ADC1000 × 100) to differentiate recurrent tumors from posttreatment changes after treatment of HSNCC. 20 patients (16 M, 4 F) underwent MR Imaging between 2 and 16 months (mean 7) after treatment.

MR imaging findings in alcoholic and nonalcoholic acute Wernicke's encephalopathy: a review.

Wernicke's encephalopathy (WE) is a severe neurological syndrome caused by thiamine (vitamin B1) deficiency and clinically characterized by the sudden onset of mental status changes, ocular abnormalities, and ataxia. Apart from chronic alcoholism, the most common cause of WE, a lot of other conditions causing malnutrition and decreasing thiamine absorption such as gastrointestinal surgical procedures and hyperemesis gravidarum must be considered as predisposing factors. Due to its low prevalence and clinical heterogeneity, WE is often misdiagnosed, leading to persistent dysfunctions and, in some cases, to death.
