“…The presence of fat–fluid levels has been said to be highly specific for teratomas. [2021] The presentation as a predominantly thin-walled large cyst with nonenhancing walls, few incomplete thin septae and containing clear fluid (Case 7) is unusual. This tumor had a very small solid component with minimal calcification that was overlooked and a strong possibility of a retroperitoneal lymphatic cyst was entertained preoperatively.…”

Aim:To review the experience with the diagnosis and management of extragonadal germ cell tumors (GCT) with a subset analysis of those with atypical features.Materials and Methods:A retrospective chart review of patients of extragonadal germ cell tumors between 2000 and 2010 was carried out.Results:Fifteen children aged 7 days to 15 years (median, 1.5 years) were included. Three had an antenatal diagnosis (one sacrococcygeal, one retrobulbar, one retroperitoneal tumor) and were operated in the neonatal period. The locations were distributed between the retrobulbar area (1), anterior neck-thyroid gland (1), mediastinum (4), abdominothoracic extending through the esophageal hiatus (1), retroperitoneal (4) and sacrococcygeal (4). On histological examination, five harbored immature elements while two were malignant; the latter children received postexcision adjuvant chemotherapy. There was no mortality. At a median follow-up of 4.5 years (6 months to 8 years), 14/15 have had an event-free survival. One immature mediastinal teratoma that recurred locally 7.5 years after the initial operation was excised and adjuvant chemotherapy instituted.Conclusions:Extragonadal GCTs in children are uncommon and occasionally present with atypical clinical, radiological and histological features resulting in diagnostic and therapeutic dilemmas.

“…Calcification can be detected in %20-50 of cases on CT, which is typically fine and speckled. On MRI, GNs show low signal intensity on T1-W images and high or isosignal intensity on T2-W images, depending on the proportion of stroma included in the mass [2,9]. In Figure 1; macroscopic appearance with lobulated contour of mass and T1-W MRI features has been shown.…”

“…In contrast to neuroblastoma, GN is benign and mature form of tumors that originate in neural crest. The most common location of GN is the posterior mediastinum (%40), retroperitoneum (%35), adrenal gland (%21), and neck (%8) [9]. Despite being detected in large sizes, retroperitoneal GNs are mostly asypmtomatic and found incidentally.…”

A B S T R A C TGanglioneuroma is a rare benign tumor originates from neurol crest and may develop anywhere along the sympathetic nervous system is present. Nearly all patients with ganglioneuroma are older than 10 years old. In most cases ganlioneuromas are detected incidentally during work-up for unrelated conditions. Nevertheless, radiological and differential diagnosis of retroperitoneal masses may be challenging. We present management of a 6-year-old boy with ganglioneuroma that located in left retroperitoneum.

“…Clinical findings of teratomas depend on the size and the location of the tumor. Most teratomas are predominantly cystic but imaging findings are variable, with solid, multicystic, or heterogeneous appearance [4,5]. US shows an anechoic or hypoechoic cystic mass with internal hyperechoic areas indicative of such ectodermal components as teeth, hair, fat, and calcification [6].…”

Abdominal nonparenchymatous cystic lesions and their mimics in children

et al. 2014

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.
