PULMONARY-EMBOLISM AFTER INVASION OF AN A NGIOMYOLIPOMA OF THE KIDNEYIN THE INFERIOR VENA-CAVA

Under the suspicion of a malignant renal tumour a nephrectomy was perf ormed in a female patient. During the operation she developed an acute hemodynamic instability. A fulminant pulmonary embolism was diagnosed by means of angiography, and with extracorporeal circulation a thromb ectomy was performed. The histological examination showed that the thr ombotic material was from an angiomyolipoma of the kidney. Although th ere were also vital tumour cells in the thrombotic material we could n ot find any proliferation during the following eleven months but even a resolving of the residual embolized tumour material in the small pul monary arteries.
