Abdominal mass
Associated symptoms
Detailed history:
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Examine the patient: ❑ Vital signs
❑ Skin
❑ Inspection
❑ Palpation
❑ Pelvic exam in females | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Consider extraabdominal differential diagnosis: ❑ aaaa | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
❑ Assess hemodynamic stability | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
If the patient is unstable, Stabilize the patient: ❑ Establish two large-bore intravenous peripheral lines ❑ NPO until the patient is stable ❑ Supportive care (fluids and electrolyes as required) ❑ Place nasogastric tube if there is bleeding, obstruction, significant nausea or vomiting ❑ Place foley catheter to monitor volume status ❑ Cardiac monitoring ❑ Supplemental oxygen as needed ❑ Administer early antibiotics if indicated | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
If the patient is stable, Order laboratory tests: ❑ Pregnancy test (required in women of child-bearing age) ❑ CBC, Hematocrit (thrombocytopenia, leukopenia, anemia may be associated with splenomegaly) ❑ Urinalysis Order imaging studies: *Order the tests to rule in a suspected diagnosis or to assess a case of unclear etiology *In case of elderly patients, immunocompromised or those unable to provide a comprehensive history, order broader range of tests | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Signs of peritonitis or shock ❑ Fever ❑ Abdominal tenderness ❑ Abdominal gaurding ❑ Rebound tenderness (blumberg sign) ❑ Diffuse abdominal rigidity ❑ Confusion ❑ Weakness ❑ Low blood pressure ❑ Decreased urine output ❑ Tachycardia | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
No | Yes | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Table illustrates common imaging findings and management of stabke abdominal masses.[1][2][3]
Cause of abdominal mass | CT scan | Ultrasound | MRI | PET scan | Management |
---|---|---|---|---|---|
Hepatic cyst | Reserved for more complicated cases.

|
| ||
Hemangiomas | Asymmetric peripheral enhancement on IV contrast (diagnostic potential) |
| |||
Hepatic adenomas | Well-circumscribed hypo-intense lesions. | ||||
Hepatocellular carcinoma | With IV contrast, diffuse enhancement with arterial phase contrast, and then washout during delayed venous images. |
| |||
Focal nodular hyperplasia | Well-circumscribed mass with central stellate scar. Hyperintense on arterial phase and isodense on venous phase (IV contrast). | Reassurae and observe (no malignant potential) | |||
Cholangiocarcinoma | Modality of choice for diagnosis and staging | Surgical resection with negative margin. | |||
Hepatic metastatsis | Hypo-intense on venous phase contrast.Does not reliably detect lesions <1 cm. |
|
| ||
Splenomegaly |
|
Doppler can determine the splenic artery and splenic vein patency. |
| ||
Cystic pancreatic mass |
|
| |||
Solid pancreatic mass | |||||
Retroperitoneal Sarcoma | Chest, abdomen and pelvis contrast-enhanced CT for diagnosis, staging, and ruling out metastatic disease. | MRI with gadolinium is an alternative in case of contrast allergy, pelvic involvement, and equivocal CT imaging findings. | Not routinely used. |
| |
AFP level above 500 mg/dL should raise concern for the presence of HCC.
