Cystic pelvic masses can represent a diagnostic challenge with its broad spectrum of differentials ranging from benign to malignant. Ultrasound is often the preliminary evaluation with MRI a next step when more information is needed. Proper diagnosis provides guidance to the clinical team with management ranging from watchful waiting to surgery. This poster will use a case-based approach to review the variety of cystic pelvic masses in pediatric patients, discuss salient imaging features, an approach to imaging workup, and treatment and prognosis.

Liver tumors account for 1-4% of all pediatrics malignancies. Most primary liver tumours in children are malignant, but one-third are benign. Mesenchymal hamartoma of the liver, though rare is the second most frequent benign liver mass in children. Generally occurs in children less than 2 years of age with a male preponderance (male: female, 2:1). We report a case of mesenchymal hamartoma of the liver in an 11 month-old female presented at the emergency department with abdominal distension of two months of evolution associated with intermittent vomiting, diarrhea and chronic malnutrition. Abnormal labs included elevated alpha-fetoprotein levels (15006 ng/ml) and non detectable beta Human Chorionic Gonadotrophin. The liver function was normal. Imaging demonstrated an abnormal abdominal X-ray, with soft tissues mass enlargement and displacement of bowel. An ultrasound revealed a mixed mass (cystic-solid) liver in segment VII. On colour-Doppler flow imaging, there was evidence of increased vascularity. Contrast-enhanced CT scan of the abdomen in arterial and venous phases showed a large cystic mass in the left lobe of the liver, with peripheral solid tissue, very vascularized in both vascular secuences. Percutaneous biopsy was done and pathology confirmed mesenchymal hamartoma. The patient underwent left hepatectomy. The patient evolved successfully. Read More

This case series will present a pictorial review of common and rare differentials for cystic lung pathology in the paediatric population, with cases taken from our tertiary paediatric institution.
Cystic lung lesions in children can present a diagnostic challenge due to a wide variety of potential aetiologies. Our review includes rarer pathologies such as our highlighted case of kerosene ingestion, where clinical history was crucial in establishing a diagnosis, and an atypical bilateral pleuropulmonary blastoma giving the appearance of a more diffuse process. These are presented alongside more commonly seen pathologies such as congenital pulmonary airway malformations, Langerhans cell histiocytosis, ChILD, and post infective sequelae. We present the clinical and radiological findings of these pathologies, with some histopathological correlation, highlighting the typical radiographic features of both these key differentials for cystic lung lesions, as well as rare differentials to consider in difficult cases. Multiple imaging modalities, including computed tomography and plain radiography, as well as multi-disciplinary discussion played a crucial role in establishing accurate diagnoses.
Understanding the clinical presentation in children with cystic lung pathology is crucial in correct diagnosis, and rare differentials must be considered in correlation with clinical history when evaluating cystic lung lesions. In the paediatric population, accurate and timely diagnosis is essential for starting appropriate management, excluding potentially malignant pathologies, and improving outcomes. Read More

Cystic liver lesions in the pediatric population are relatively uncommon but encompass a wide range of pathologies. It is important for radiologists to be familiar with the differential diagnosis and imaging characteristics of each entity because prognosis and treatment vary widely. This educational exhibit will review the appearance of various cystic liver lesions in the pediatric population by ultrasound, CT, and MRI and will review clinical presentation and genetic/biologic causes.
