Pediatric Hepatic Cystic Lesions: Differential Diagnosis and Multimodality Imaging Approach

Neonatal pyogenic liver abscess following omphalitis: A case report

“…There are other differential diagnoses of hepatic cystic lesions in children, including neoplastic (hepatoblastoma, infantile hemangioendothelioma, and mesenchymal hamartoma), posttraumatic (hepatic hematoma, biloma), or iatrogenic (umbilical vein catheter). Familiarity with imaging findings and clinical features is essential for accurate diagnosis of pediatric hepatic cystic lesions, which in turn can guide appropriate clinical management [ 13 ]. Liver abscesses tend to be hypoechoic and are usually solitary.…”

“…In contrast, tumors typically have a solid appearance and may be calcified. Serum alpha-fetoprotein levels may be helpful in differentiating malignant and benign hepatic masses from liver abscesses [ 13 , 14 ].…”

“…Ultrasound also specifies the location, number, and size of the abscess, reveals associated biliary anomalies, and allows for percutaneous drainage [ 2 , [12] , [13] , [14] ]. The sensitivity of ultrasound, CT and MRI is approximately the same [ 12 , 14 ], but the latter two are not operator dependent and therefore provide a more accurate diagnosis.…”

Abdominal pain in an adolescent boy

“…The majority of these cysts are congenital and patients usually present in early life with abdominal pain and jaundice, though pancreatitis is a described presentation 1. MRCP is the preferred modality for diagnosis and based on their location and morphology; choledochal cysts can be subdivided into six types (Todani Classification): type I–VI2 (figure 63). Type III cysts, also known as choledochocheles, are characterised by dilation of just the intraduodenal portion of the common bile duct.…”
