Recurring multicystic inflammatory pseudotumor of the liver: a case report

Inflammatory pseudotumor (IPT) of the liver is a rare benign lesion for which imaging diagnosis remains a challenge. We report the case of a 39-year-old Algerian woman, who presented epigastric pains combined with fever and jaundice. Ultrasound, CT scan and MRI showed the presence of a 10 cm-long multi-septated cystic mass of the left lobe, with peripheral enhancement. A left-hepatectomy was performed and histopathology revealed an IPT of the liver. During the 4 following years, the patient had three other recurrences of liver IPT at various locations distinct from the original, revealed by the same clinical symptoms. During these relapses, the lesions did regress thanks to a medical treatment. This observation underlines the difficulty of the diagnosis and treatment of liver IPT.
