Abstract:
We describe the case of an 80-year-old man who came to our observation with pain in his left side and iliac region. Ultrasonography showed an incidentaloma with a largest diameter of 10 cm in the left suprarenal fossa. It extended downward and anteriorly from the apex of the left kidney; the picture was suggestive of a saccate hematoma. Further examination resulted in a diagnosis of an adrenally located extranodal non-Hodgkin's lymphoma and the patient was treated accordingly.
