Retroperitoneal Bronchogenic Cyst Mimicking a Pancreatic Cystic Lesion with Extremely High Level of Intralesional Fluid CA-19.9 Antigen: Benign in Disguise.

Bronchogenic cysts are congenital benign tumors resulting from abnormal budding of the primitive foregut. Usually presented on the posterior mediastinum, its presence on the retroperitoneum is extremely rare. We present an asymptomatic lady patient with a retroperitoneal cystic lesion that was submitted to endoscopic ultrasound-guided biopsies and intracystic fluid aspiration with histology excluding malignance despite intracystic fluid biochemical analysis that disclosed extremely high carbohydrate antigen 19-9. Definite diagnosis of bronchogenic cyst was only possible after complete surgical resection of the lesion. Furthermore, we discuss the use of this antigen as a tumor marker in this situation and its relevance to the preoperative diagnosis of such lesions.

Intrapartum diagnosis and treatment of longitudinal vaginal septum.

Longitudinal vaginal septum is a rare Müllerian malformation that may be associated with dyspareunia, dysmenorrhea, primary amenorrhea, and infertility. In this report, the authors present a case of longitudinal vaginal septum in a 15-year-old patient with a full-term pregnancy whose diagnosis was only made during labor following bidigital vaginal and speculum examination. Septoplasty was performed during the second stage of labor. Both mother and child progressed satisfactorily and were discharged from hospital in good health. Six months later, ultrasonography, hysterosalpingography, and hysteroscopy were carried out and no other associated abnormality was found.
