From your description, this most likely represents a simple renal cyst which is very common. Characteristically, lymphoma has a diferent appearance and will infiltrate
into the kidney which a cyst won't do. Very rarely lymphoma is seen as a solitary renal mass but on a contrast examination this normally enhances and therefore suggests the diagnosis is not just a simple renal cyst. Finally, isolated renal lymphoma is rare, so unless your husband has lymphoma or evidence of this elsewhere, then lymphoma is a very unlikely diagnosis
