Abstract
Zusammenfassung. In einem Sonografie-Kurs des Medizinstudiums wurde bei einer gesunden, asymptomatischen Studentin eine grosse, flüssigkeitsgefüllte Raumforderung mittig im Unterbauch entdeckt und eine Überlaufblase vermutet. Trotz diverser interdisziplinärer Abklärungen konnte die Ätiologie der zystischen Formation nicht geklärt werden. Bei zunehmend symptomatischer Patientin wurde drei Monate nach Entdeckung des Zufallsbefundes die Diagnose eines zystischen Tumors im Unterbauch mit sekundärer Harnretention gestellt und eine operative Zystenexzision durchgeführt. Es zeigte sich eine grosse, seröse Paratubarzyste links mit Torsion der Tube ohne Ischämiezeichen und ohne Malignität. Zufallsbefunde im Ultraschall-Unterricht sind keine Seltenheit. Kursteilnehmende, Tutorinnen und Tutoren sowie Kursleitende müssen sich dessen bewusst sein und ein klares Prozedere kennen, um damit fachgerecht umzugehen.
Abstract. During a sonography class in medical school, a large fluid-filled mass was discovered in the center of the lower abdomen in a healthy, asymptomatic female student; an overflow bladder was suspected. Despite various interdisciplinary investigations, the etiology of the cystic formation could not be clarified. Three months after discovery of the incidental finding, the increasingly symptomatic patient was diagnosed with a cystic tumor in the lower abdomen with secondary urinary retention, and surgical cyst excision was performed. A large, serous Paratubular cyst was found on the left side with torsion of the tube without signs of ischemia and without malignancy. Incidental findings in ultrasound teaching are not uncommon. Course participants, tutors, and course instructors must be aware of this and have a clear procedure at hand in order to deal with it.
