Management Approach for Splenic Mass

Diagnostic Evaluation

The American College of Radiology recommends contrast-enhanced CT as the gold standard for evaluating splenic masses, providing detailed information about pattern, distribution, and associated abnormalities 1
Doppler ultrasound and contrast-enhanced ultrasound are useful adjuncts to evaluate splenic vascularization and can be used for follow-up 1
The diagnostic approach should be based on imaging characteristics including enhancement patterns 1

For hemodynamically stable patients with blunt splenic trauma, the Eastern Association for the Surgery of Trauma recommends non-operative management as first-line treatment, regardless of injury grade 2, 3
Non-operative management should only be attempted in facilities with capability for continuous patient monitoring, angiography, trained surgeons, immediately available operating room, and immediate access to blood products 3
Consider angiography/angioembolization for patients with contrast blush on CT scan, though this finding alone is not an absolute indication for intervention in stable patients 3, 4
Operative management should be performed when the patient is hemodynamically unstable despite resuscitation 1
Operative management should be performed when non-operative management fails with significant drop in hematocrit or continuous transfusion requirements 2
Operative management should be performed when peritonitis or other indications for laparotomy are present 2, 4

For calcifications related to prior splenic trauma, assess hemodynamic stability and consider non-operative management if stable 1
For calcifications or masses associated with infectious or inflammatory conditions, treat the underlying cause with appropriate antimicrobial therapy 1

For low-grade splenic injuries or benign lesions, routine post-discharge follow-up imaging may not be necessary 1
For moderate to severe injuries, consider CT follow-up before discharge 1
In patients with underlying splenic pathology, coagulopathy, or neurological impairment, post-discharge CT follow-up should be considered 1
Activity restriction may be advised for 2-6 weeks for minor injuries and up to 2-4 months for moderate and severe injuries 1

Perioperative mortality of splenectomy ranges from 5-10%, with complications occurring in approximately 50% of patients 1
Patients undergoing non-operative management should be counseled about warning signs and advised not to remain alone during the first weeks after discharge 1
