Onbir Aylık Erkek Bebekte Retroperıtoneal Matür Teratom

Retroperitoneal Matür Teratom(RMT), sıklıkla yenidoğan ve genç adultlarda görülen nadir bening tümörlerdir. Orta hat boyunca herhangi bir yerden köken almalarına karşın, genellikle sakrokoksigeal, gonadal, mediastinal, retroperitoneal, intraservikal ve intrakranial lokalizasyonlarda yerleşirler. Klinik davranışları, yerleşim yeri ve hacmine bağ- lı olarak değişir. 11 aylık erkek bebek bronkopnömoni önteşhisi ile hastanemize kabul edildi. Fizik muayenesinde yaygın abdominal distansiyon, abdominal radyografisinde ise opasite saptandı. Ultrasonografinde kistik kitle tespit edilen olguya, bilgisayarlı tomografi(CT) ve manyetik rezonans görüntüleme(MRI) tetkikleri yapıldı. Tüm tanısal tetkikler iyi sınırlı ekspansil kitleyi gösterdi. Olgu opere edilip, kitlenin tümü eksize edildi. Histopatolojik muayenede malign özellikler içermeyen matür kistik teratom olduğu tespit edildi. RMT, abdominal distansiyonlu çocuklarda ayı- rıcı tanıda daima akılda tutulmalı ve abdominal ultrasonografi tetkiki bu hastalarda yapılmalıdır.

Retroperitoneal Mature Teratoma In An 11-Month-Old Baby

Retroperitoneal mature teratomas (RMT) are rare benign tumors, most commonly found in neonates and young adults. Although they may originate anywhere along the midline, teratomas are most commonly found in sacrococcygeal, gonadal, mediastinal, retroperitenoal, cervicofacial and intracranial locations. Clinical behavior varies by site and size. An 11-month-old baby with a prediagnosed of bronchopneumonia was admitted to our hospital. Common abdominal distension and opacity were determined in physical examination and abdominal radiography, respectively. Abdominal sonographic examination was performed and revealed a cystic mass. Also, computerize tomography (CT) and magnetic resonance imagines (MRI) were performed. All of the diagnostic imaging showed that the mass had a well-defined counter and expansile. Subsequently the patient was operated and all of the mass was excised. Histopatological examination revealed a mature cystic teratoma without malignant features. RMT should always be kept in mind in the differential diagnosis in children with abdominal distension. Abdominal ultrasonography should be made in these patients.
