Abdominal nonparenchymatous cystic lesions and their mimics in children

Abstract

Abdominal cystic lesions in children may originate from parenchymatous organs or from nonparencyhmatous structures. Although these lesions have welldescribed imaging features, proper diagnosis usually depends on the accurate determination of the origin of the lesion. Because large lesions may resemble each other it is difficult to identify the site of origin, which results in a diagnostic dilemma. In this pictorial essay we describe abdominal nonparenchymatous cystic lesions and their mimics arising from parenchymatous organs in children.

Unique coexistence of chronic midgut malrotation, mesenteric cyst, and pancreas divisum in a Crohn's disease patient: MR-enterography assessment

“…They can be symptomatic when causing obstruction, due to extrinsic compression or volvulus induction, or when rupture occurs [15] , [16] , [17] .…”

“…Also in this case, MRI can rely on different sequences in order to further characterize the content on the basis of the signal intensity [2 , 4 , 16] .…”

The Role of Tissue Harmonic Ultrasonography and Computerized Tomography in the Diagnosis of Intraabdominal Cystic Lesions

“…Congenital cystic lesions and duplication cysts can be seen frequently in the abdominal cavity in the pediatric age group [16][17][18][19] .…”

A rare presentation of mesenteric cystic lymphangioma in 5-year-old girl

“…Imaging is beneficial in the diagnosis of mesenteric lymphangiomas. Ultrasonography is used for the initial diagnosis of the lesion because it is considered a highly sensitive tool for diagnosing cystic lesions and due to lack of radiation exposure [16,17] CT-scan provides information on anatomical localization, size, and involved structures, which is crucial to plan the surgical treatment. Therefore it was used in our patient to complete the diagnostic imaging, nevertheless, magnetic resonance imaging is also considered to be an effective examination in these cases [16].…”
