We present a case of cerebellar tumoral multiple sclerosis in an 11-year-old girl and emphasize these two features: (1) Tumoral multiple sclerosis can occur within the posterior fossa and should be strongly considered in the differential diagnosis of mass lesions of the posterior fossa when typical white matter lesions are seen on T2-weighted images. (2) Tumoral multiple sclerosis can demonstra...

BACKGROUND Pre-therapeutic pathological diagnosis is a crucial step of the management of pulmonary nodules suspected of being non small cell lung cancer (NSCLC), especially in the frame of currently implemented lung cancer screening programs in high-risk patients. Based on a human ex vivo model, we hypothesized that an embedded device measuring endogenous fluorescence would be able to distingui...

INTRODUCTION Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE A 11-m...

Purpose. To assess the diagnostic accuracy of dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSCE-MRI) in differentiation between benign and malignant liver lesions by assessment of tumoral perfusion parameters. Methods Materials. Seventy-three patients with known focal liver lesions, including 45 benign (16 FNH, 27 angiomas, and 2 abscesses) and 28 malignant ones (17 meta...

Presenter: Paul Thevenot PhD | Ochsner Health System Background: In hepatocellular carcinoma (HCC) patients awaiting liver transplantation (LT), liver-directed therapy (LDT) serves as a bridge to LT and improves overall survival. Patients with an objective response LDT are more likely have lower grade HCC at improved recurrence-free survival after LT. Unfortunately, >80% of complete radiographi...

Contrast-enhanced magnetic resonance imaging (CE-MRI) is a valuable technique for the diagnosis of liver diseases. As gadocoletic acid trisodium salt (B22956/1), a new contrast agent showing high biliary excretion, may be potentially advantageous in hepatobiliary imaging, the aim of the study was to investigate the molecular mechanisms of hepatic transport of the B22956 ion in a cellular model ...

Three cases of bone changes caused by foreign bodies that appeared to be tumoral lesions or pseudotumors, were observed in young male patients who presented with pain, localized inflammation, and radiographic and bone scan findings suggestive of tumoral or pseudotumoral lesions. Accurate diagnosis was made at surgery when the foreign body was retrieved. Following removal of the foreign body, po...

The results of a multicentric retrospective analysis of 265 liver resections for hepatocellular carcinoma in cirrhotic patients have been collected and assessed. Overall operative mortality was 9.1%. The actuarial 3-year survival was 46.5%. Better results were obtained in patients with encapsulated lesions and alphafetoprotein levels less than 400 ng/dl. Tumoral recurrence, which was the main c...

A 20 year-old man presented to our clinic with multiple warts on both hands and tumoral lesions on his face but otherwise healthy. On dermatological examination, numerous brown-black papular lesions, changing from 2 to 5 cm in diameter were found on his face along with multiple, flesh-coloured, flat-topped papules on the dorsa of his hands. A tumoral lesion, approximately 3 cm in diameter on th...
