A recurring umbilical discharge â even after antibiotic treatment and drainage â along with a 3.5x2.4 cm cystic lesion on CT scan suggests this is not a simple abscess but likely a persistent umbilical cyst or remnant tissue that keeps re-infecting. Falling and re-triggering drainage means the underlying cyst cavity has not fully resolved. Without surgical removal of the cystic lesion, this cycle of infection, drainage, and recurrence is likely to continue.
Next Steps
You need a surgical consultation urgently â a general surgeon should evaluate whether the umbilical cyst needs to be excised. Antibiotics and drainage alone won't provide permanent resolution if a cystic cavity remains. Please consult me directly on Practo for a detailed evaluation.
