Sonographic appearance of primary retroperitoneal cysts

Symptomatic Perirenal Serous Cysts of Müllerian Origin Mimicking Renal Cysts on CT

OBJECTIVE

Our aim was to describe the clinical presentation, CT appearance, and management of a series of symptomatic perirenal serous cysts of müllerian origin, confirmed by laparoscopic resection.

CONCLUSION

Perirenal serous cysts of müllerian origin are uncommon lesions that may present as large symptomatic perirenal cystic masses mimicking exophytic renal cysts on CT. Serous cyst of müllerian origin should be considered in the differential diagnosis when CT reveals a large solitary perirenal cyst in a woman with flank or abdominal pain or both. Laparoscopic resection may be an effective treatment of such cysts.

Pediatric abdominal lymphangiomas: a plea for early recognition

Abdominal lymphangiomas are usually classified together with mesenteric cysts. However, they differ by location, histology, and potential for recurrence, and should be considered a separate clinical entity. Thirteen children, aged 2 weeks to 11 years (mean, 5.8 years), with abdominal lymphangiomas were identified over the past 16 years at this institution. Of these, 12 were symptomatic. Abdominal pain (11), vomiting (8), increased abdominal girth (8), and nausea (6) predominated. Other presentations were less frequent. Symptoms were present for an average of 2 months (7 less than 1 week) before correct diagnosis. An abdominal mass was palpable in 10 cases. Intestinal gangrene secondary to volvulus was present in 2. Although multiple imaging modalities were used ultrasonography (8/8) and computed tomography (CT; 4/4) proved most expedient and reliable. In 2 cases, the lymphangioma could not be completely resected. There was 1 recurrence. Although intraabdominal cystic lesions are described in the literature as relatively symptom-free, our experience suggests otherwise. In this series, abdominal pain and an abdominal mass were common. Catastrophic complications can occur and excision is facilitated by earlier diagnosis and the benefit of smaller size. Ultrasound and CT can accurately diagnose the lesion and should be used liberally in children with intermittent or ill-defined abdominal pain, leading to prompt recognition and definitive treatment.
