Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a well - circumscribed , circular , 6 .3 cm calcified mass present in the left upper quadrant . This may represent a calcified splenic lesion / cyst , versus a large pancreatic pseudocyst , and less likely a calcified splenic artery aneurysm . The location of the lesion makes this less likely a pancreatic pseudocyst . Correlation with an abdominal ultrasound is recommended if this is not a previously known finding . The mediastinal structures are within normal limits . There is no cardiomegaly . The hila are unremarkable . The lung fields are clear without evidence of focal consolidation . There are no pneumothoraces or effusions apparent .
    OUTPUT:
    
Circular calcified left upper quadrant abdominal lesion with differential including calcified splenic cyst , versus less likely a large pancreatic pseudocyst or calcified splenic artery aneurysm . Recommend correlation with abdominal ultrasound .
