Umbilical catheters provide intravascular access in the neonatal period that is lifesaving and relatively easy to obtain. However, they are associated with numerous complications related to their placement and use. These may occur because of injuries to vessels and adjacent structures at the time of or following catheter placement; an example is a liver hematoma caused by focal perforation of the umbilical or portal veins during attempted passage of the catheter into the ductus venosus. Complications may also arise from the use of a malpositioned catheter. Pleural effusions and ascites composed of total parenteral nutrition solutions may result from the use of an umbilical venous catheter that terminates in the portal venous system. Complications may be caused by otherwise well positioned, normally functioning catheters, which are innately thrombogenic and may cause thrombosis of the aorta and branches, portal venous system, or caval tributaries, with potentially devastating consequences. Finally, catheter-associated blood stream infection is always a risk during placement and subsequent use. The resulting bacteremia can lead to life-threatening sepsis and additional complications such as septic thrombosis and mycotic aneurysm. This educational review presents a spectrum of complications related to umbilical catheters, organized according to the framework outlined above. The review includes images of cases illustrating both common and unusual entities and a discussion of their salient imaging and clinical features. Read More

CT can be a powerful tool for the evaluation of the chest and abdominal pathology in children. While not as commonly used as in the USA, CT studies represented approximately 15% of cases received from low- and lower-middle income Countries for expert second opinion by a pediatric radiologist in the WFPI teleradiology platform, over the last 4 years. This pictorial review lists the indications, details the technical parameters, and exemplifies imaging findings of CT studies from this setting. Read More

Multicystic renal tumors (MCRTs) in children encompass a rare and diverse group of neoplastic entities, including cystic nephroma (CN), cystic partially differentiated nephroblastoma (CPDN), and cystic Wilms' tumor (CWT). CPDN occupies an intermediate status between the benign CN and the malignant CWT. Despite marked histological differences, distinguishing these tumors clinically is a complex undertaking. A 33-month-old male child presented with abdominal pain and recurrent episodes of screaming and knee-drawn postures during sleep. The patient had a recent history of mild gastroenteritis, but no recent travel or sick contacts. Physical examination revealed a palpable abdominal mass. Abdominal ultrasound detected a distinct multicystic lesion in the upper left quadrant, separated from the spleen. While gastric involvement was considered, the lesion appeared isolated from the gastric bubble and fixed. Potential diagnoses included a unique gastric bezoar, vascular mass lesions, and an exophytic renal lesion. MRI revealed a large, multiloculated cystic lesion with septations, primarily contained within the renal boundaries, but protruding medially. Noticeable enlargement of adjacent retroperitoneal lymph nodes prompted consideration of an MCRT, including CWT. An atypical multicystic dysplastic kidney was also considered. The patient underwent surgical resection followed by histopathological analysis, which confirmed the diagnosis of CN. While radiological imaging aids in diagnosing MCRT, distinguishing between CN, CPDN, and CWT often necessitates histopathological analysis. Vascular invasion can point to a diagnosis of CWT. The presence of solid elements is less helpful, as discerning whether these are part of the tumor or part of the native kidney can be difficult. The accuracy of the diagnosis plays a crucial role in determining the necessity for chemotherapy and/or radiation therapy. This case report highlights the diagnostic complexities associated with MCRTs in pediatric patients and underscores the significance of a multidisciplinary approach that incorporates clinical, radiological, and histopathological evaluations to provide the best possible care for these young patients.
