A case of lipoblastoma in a pediatric patient.

Lipoblastoma is a benign soft tissue tumor that originates from embryonic white fat. Lipoblastoma presents as a slow-growing mass that commonly occurs in the extremities of young children. Histological examination remains the gold standard in confirming lipoblastoma; however, radiology examination can help identify and evaluate the extent and characterization of the mass prior to the excision. Here, we report a 7-year-old male patient who presented with a painless mass in the right popliteal extending to the proximal cruris areas, and the imaging modalities suggested the presence of fat within the mass. The patient then underwent complete excision, and histopathology examination revealed lipoblastoma. This study highlights the possibility of lipoblastoma in older children and the role of imaging examinations in the diagnosis.

Mayer-Rokitansky-Küster-Hauser Syndrome with Situs Inversus Totalis: A Rare Case Report.

BACKGROUND Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a complex disorder of the female reproductive system that results in an absent uterus and vagina. MRKH syndrome can be an isolated anomaly (typical) or accompanied by other organ anomalies (atypical). Due to the similarity of symptoms with other congenital gynecological diseases, imaging modalities remain the most important tools in establishing the diagnosis by visualizing internal genital and detecting possible organ malformations. CASE REPORT We present a very rare case of a female with primary amenorrhea. Pelvic magnetic resonance imaging (MRI) showed the absence of a uterus and vagina with possible Mullerian remnants, as well as an incidental finding of a right ectopic kidney. Abdominal ultrasonography and chest X-ray showed that the patient also had situs inversus totalis. CONCLUSIONS MRKH syndrome may be associated with situs inversus totalis due to possible early embryologic malformations causing both conditions; however, the exact mechanism is still unknown. This report should serve as a more recent attempt to question whether situs inversus totalis is related to MRKH and to emphasize the importance of imaging modalities, especially MRI, in establishing the diagnosis of MRKH syndrome and the associated malformations.

A Rare Case of Giant Mediastinal Ganglioneuroma in A 3-year-old.

Ganglioneuroma is a rare, differentiated, and benign neurogenic tumor that could grow into a huge size with minimal or no symptoms at all. Ganglioneuroma is typically found in older children or adults and is commonly detected within the posterior mediastinum (other than retroperitoneal). Here, we present a case of a 3-year-old patient with shortness of breath, and radiological examination showed a giant mediastinal tumor which proved to be a ganglioneuroma after histopathological examination. This study highlights the possibility of ganglioneuroma occurring in younger children and the role of imaging in assessing ganglioneuroma as a posterior mediastinal tumor.
