La fibrose rétropéritonéale est le mode de découverte de nombreuses pathologies, notamment tumorales. Nous rapportons chez un homme de 83ans une observation de fibrose rétropéritonéale révélatrice d’une linite digestive étendue multimétastatique. La linite gastrique peut se présenter sous de nombreuses formes cliniques trompeuses et syndromes paranéoplasiques, causes de retard à son diagnostic.

Retroperitoneal fibrosis may reveal many diseases, including neoplasias. An 83-year-old man presented with an acute renal failure due to compressive retroperitoneal fibrosis. Clinically the only abnormal feature was a cutaneous subclavicular infiltrated lesion and laboratory features included hypereosinophilia, anemia and elevated acute phase reactants. A thoracic CT-scan showed pleuritis and para-oesophagal lymph node and the 18FDG-PET-scan an hypermetabolism lesion of the oesophagus. Gastroscopy and colonoscopy found a gastric linitis, already multimetastatic at diagnosis. The gastric linitis can present with many decepting clinical forms, increasing the risk of delayed diagnosis.
