A case report for a diagnostic dilemma of a giant intra-abdominal cyst with an uncertain origin

[Rare Incidental Finding during a Student Ultrasonography Course - A Case Report]

Rare Incidental Finding during a Student Ultrasonography Course - A Case Report 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.
