Management of Splenic Calcification

Diagnostic Approach

Contrast-enhanced CT scan is the gold standard for evaluating splenic calcifications, providing detailed information about the pattern, distribution, and associated abnormalities 1, 2
Doppler ultrasound (DUS) and contrast-enhanced ultrasound (CEUS) are useful adjuncts to evaluate splenic vascularization and can be used for follow-up 1, 2, 3

For stable patients with incidental findings of splenic calcification, clinical observation with serial examinations is appropriate, and no specific intervention is typically required if the patient is asymptomatic 2, 3
For calcifications related to prior splenic trauma, assess hemodynamic stability, and for hemodynamically stable patients, non-operative management is recommended 1, 3
For calcifications associated with infectious or inflammatory conditions, treat the underlying cause with appropriate antimicrobial therapy, and consider splenic abscess if patient presents with persistent fever, recurrent bacteremia, or other signs of sepsis 4
For calcifications associated with myeloproliferative disorders, hydroxyurea is the first-line treatment for associated splenomegaly, and consider splenectomy for drug-refractory symptomatic splenomegaly, portal hypertension, or transfusion-dependent anemia 5

Splenectomy should be considered in scenarios such as hemodynamic instability despite resuscitation efforts, failed non-operative management, drug-refractory symptomatic splenomegaly, splenic abscess not amenable to percutaneous drainage, and symptomatic portal hypertension 1, 6, 5, 7

For low-grade splenic injuries, routine post-discharge follow-up imaging is not necessary, but for moderate to severe injuries, consider CT follow-up before discharge, and in patients with underlying splenic pathology, coagulopathy, or neurological impairment, post-discharge CT follow-up should be considered 3
Activity restriction may be advised for 2-6 weeks for minor injuries and up to 2-4 months for moderate and severe injuries 3

Perioperative mortality of splenectomy ranges from 5-10%, with complications occurring in approximately 50% of patients, including bleeding, thrombosis, subphrenic abscess, accelerated hepatomegaly, and extreme thrombocytosis 5
Patients undergoing non-operative management should be counseled about warning signs and advised not to remain alone during the first weeks after discharge 3

Advise patients with recent splenic injury to avoid isolation during the first weeks and to promptly report alert symptoms such as persistent pain, fever, or hemodynamic changes, as these may indicate complications. 8
Educate patients that awareness of warning signs is more cost‑effective than routine post‑discharge imaging until complete healing is achieved. 9

For individuals with decreasing hematocrit, vascular anomalies, underlying splenic disease, coagulopathy, or neurologic impairment, a repeat contrast‑enhanced CT before discharge is recommended to identify ongoing bleeding or other complications. 9

Delayed splenic rupture may occur 4–10 days after injury, carrying a mortality rate of 5–15 % (compared with ~1 % for acute rupture), underscoring the need for vigilant monitoring during this period. 8
