[Sinistral portal hypertension with bleeding gastric varices as initial manifestation of renal-cell carcinoma]. / Hipertensión portal izquierda con sangrado por varices gástricas como forma de presentación de un hipernefroma.

We report a clinic case of renal-cell carcinoma presenting as sinistral portal hypertension; a clinical syndrome consisting of esplenic vein thrombosis manifested as isolated gastric varices with patent portal vein and normal hepatic function. The most frequent cause of this syndrome is pancreatic pathology. Renal-cell carcinoma is characterized by a wide variety of symptoms as initial manifestation. In our case, the patient developed a massive gastrointestinal bleeding secondary to isolated gastric varices caused by splenic vein thrombosis due to extrinsic compression by a hypernephroma that infiltrated the pancreas.
