Optimisation of metabolic criteria in the prognostic assessment in patients with lymphoma. A multicentre study.

Objective: To compare sensitivity, specificity and predictive value of Deauville score (DS) vs. ΔSUVmax in interim-treatment PET (iPET) and end-treatment PET (ePET), in patients with diffuse large B cell lymphoma (DLBCL), Hodgkin lymphoma (HL), and follicular lymphoma (FL).

Method: Retrospective longitudinal multicentre study including 138 patients (46 DLBCL, 46 HL, 46 FL), on whom 3 F-FDG PET/CT were performed: baseline, iPET, and ePET.

Limbic Encephalitis Diagnosed With 18F-FDG PET/CT.

Limbic encephalitis is a subacute onset syndrome characterized by short-term memory impairment, confusion, temporal lobe epilepsy, hypothalamic dysfunction, and psychiatric symptoms. Common causes are autoimmune disorders or idiopathic disease, although it has been associated to tumors. We report the case of a woman arrived at the emergency department having had fluctuating impaired memory for 2 weeks.
