CEA-Scan Finds Disease Missed by
Both CT & Pet in an Asymptomatic 
Patient with Rising Serum CEA

PATIENT HISTORY: 
    A 44 year-old female with right colon cancer resected in May 1998 followed by a hysterectomy in December of 1998. Chemotherapy started in August of 1998 continues at the time of this evaluation.

SERUM CEA LEVELS:    38 ng/ml

PRIOR DIAGNOSTIC STUDIES:
    Negative abdominal/pelvic CT (May 1999)
    Negative abdominal/pelvic PET (June 1999)

	PET Scan
	CEA-Scan

CEA-Scan FINDINGS:
    SPECT Imaging (June 1999) identifies focal activity in the right pelvis superior to the bladder.

SURGICAL FINDINGS:
    Metastatic disease in the right pelvis.

CONCLUSION:
    CEA-Scan can change patient management by identifying the source of rising serum CEA levels missed by both CT and PET.
