case_images: In figures (1a-1c), an abdominal ultrasound shows a large, walled, and multiseptated fluid collection. A small portion of the shunt catheter appears to be within this fluid collection, and thus the lesion was felt to be consistent with a pseudocyst, or CSFoma. In figures (1d-1f), a CT with IV contrast shows the same complex, multiseptated 16 x 8 x 17 cm pelvic mass emanating from the right ovary, with the distal shunt tubing draped circumferentially around the lesion, indicating that the shunt was not responsible. Surgical exploration leads to the diagnosis of teratoma.

case_images: A small portion of the shunt catheter was reported to be within this fluid collection; however; the tip could not be identified (Figure 1(a)-1(c)). The distal shunt tubing appeared to be draped circumferentially around the lesion and was not contained within the mass itself, as is generally the case with a CSF pseudocyst (Figure 1(d)-1(f)).
