Q

A 70 year old known teetotal patient is noted to have a heart murmur and careful examination reveals splenomegaly with an obvious notch and you can’t get above it. There are no visible veins on the anterior abdominal wall, and there is no ascites, so you conclude that there is no portal hypertension. Dipstick of the urine reveals microscopic haematuria. She is found to have a temperature of between 37.5oC and 38.5oC whenever it is checked.
