Pulmonary tumour and inferior vena cava tumour thrombus: rare presentation of renal transitional cell carcinoma. Case report.

A transitional cell carcinoma from the pyelocaliceal system, initially presenting as a pulmonary tumour, extended into the inferior vena cava, the tenth reported case of this type. The literature is reviewed with special reference to vena cava involvement by such tumours and immunohistochemical staining pattern.

Acute urinary retention due to sacral myeloradiculitis.

Three cases of acute urinary retention without local urological causes are described. A diagnosis of sacral myeloradiculitis of viral origin appeared more likely than a first episode of multiple sclerosis. The literature is reviewed and a protocol for the investigation of such patients is suggested.
