[Suprarenal myelolipoma: an "incidental" disease]

With the development and improvement of imaging techniques, we are witnessing a greater number of disease diagnoses considered uncommon only a few years ago. When the diagnosis of a tumoral disease occurs "incidentally" while performing an imaging examination for other reasons, we name the condition "INCIDENTALOMA". A clear example of these in suprarenal conditions is the myelolipoma. Myelolipoma is a benign and non-functioning tumour originating in the suprarenal cortex and histologically consisting of mature fat and haemopoietic tissue. Given its benign and usually inactive nature, the current approach is a conservative attitude. Surgical exeresis is only accepted when large tumoral masses are present or in complicated cases. This paper presents a new case of a 10 cm suprarenal myelolipoma incidentally diagnosed during routine ultrasound examination in a 47-year old male patient. Subsequent exeresis of the suprarenal mass and pathohistological study confirmed the diagnosis.
