Abstract
INTRODUCTION: and importance: A mature mediastinal teratoma is a rare type of tumor that can contain fully developed tissues and it is usually considered benign, more common in female and may require surgical removal. The most common locations for teratomas are the tailbone (coccyx), ovaries, and testicles, but in this case, the teratoma was located in the mediastinum. CASE PRESENTATION: Furthermore, intestinal malrotation could potentially lead the patient to gastrointestinal (GI) obstruction and PO intolerance. Here, we present a 2-month-old patient with considerable manifestation of GI intolerance due to intestinal malrotaion accompanied by mature mediastinal teratoma. CLINICAL DISCUSSION: An evaluation of malrotation should be part of every upper GI tract examination in pediatric patients, particularly newborns and infants. CONCLUSION: Finally, in this case, surgical intervention could enhance both malrotation and mediastinal teratoma.
