A bronchogenic cyst, presenting as a retroperitoneal cystic mass

Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare. Due to the mostly asymptomatic behavior and the historical confusion regarding histology, an exact prevalence is not known. We present here a case report of a retroperitoneal bronchogenic cyst. A literature review was performed for cases of retroperitoneal bronchogenic cysts written in English. Anatomopathological criteria for inclusion were pseudo stratified, ciliated, columnar epithelium together with the presence of at least one of the following: cartilage, smooth muscle or seromucous glands. In addition, the embryology, pathogenesis, radiological, clinical and suggested treatment modalities are reviewed. We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a non-functioning left adrenal mass. Our review of literature revealed only 62 potential cases of retroperitoneal bronchogenic cysts. After applying the strict anatomopathological criteria, only 30 cases of true retroperitoneal bronchogenic cysts could be identified. Retroperitoneal location of a bronchogenic cyst is rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Only histology can confirm definitive diagnosis. Surgery remains the recommended treatment of choice

Interlobar venous flow is different between left and right kidney in uncomplicated third trimester pregnancy

AIM: To investigate Doppler flow patterns of renal interlobar veins (RIV) in left (L) and right (R) kidney in relation to gestational age and to intrarenal pyelocalyceal diameters (PCD). METHODS: Cross-sectional study involving 6 groups of women: (1) non-pregnant women, women pregnant between weeks (2) 11-14, (3) 18-23, (4) 28-33, (5) 37-40 and (6) women <5 days post delivery. During standardized renal duplex ultrasound scan, PCD (mm) was measured and venous impedance index (VI = [peak flow (PV) - presystolic flow]/PV) of RIV was defined. Comparison between L and R kidney was performed by repeated-measures analysis of variance for VI and by t tests for PCD. RESULTS: A total of 150 women were examined, 25 in each group. In the early third trimester of pregnancy, L VI was significantly higher than R VI (0.38 +/- 0.01 vs. 0.33 +/- 0.01, p < 0.0001) and L PCD was significantly lower than R PCD (3.90 +/- 3.68 vs. 6.25 +/- 4.03, p = 0.03). CONCLUSION: RIV Doppler flow is different between left and right kidney only in the third trimester of pregnancy. This difference is inversely related to PCD, which may be explained by pelvic compression from the gravid uterus.status: publishe

Rhabdomyolysis after Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: A Case Report

Gastric cancer with peritoneal carcinomatosis is a disease with a poor prognosis. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) can improve prognosis, although in most cases this should still be considered as a palliative treatment. Therefore, morbidity has to be avoided at all cost as quality of life is of utmost importance. We describe the case of a 64-year-old female with an adenocarcinoma of the stomach that was initially treated with a Billroth II gastrectomy, adjuvant chemotherapy and radiotherapy. During follow-up, the diagnosis of peritoneal carcinomatosis was made, and the patient was referred for CRS and HIPEC. Postoperatively, she developed rhabdomyolysis in both gastrocnemius muscles. Renal function remained within normal limits, but ultrasonography of the lower legs suggested the presence of bilateral abscesses. Drainage with pigtail catheters was necessary for more than 1 month, significantly impairing quality of life. The objective of this case report is to heighten awareness for this complication. Rhabdomyolysis is a rare complication of CRS and HIPEC, with a significant impact on quality of life. Prevention is necessary and can be achieved by adequate surgical positioning, using the altered lithotomy position, sufficient padding and by preventing hypovolemia

An Unusual Location of Extraosseous Ewing's Sarcoma

Ewing's sarcoma (ES) is the second most common malignant bone tumor in children and young adults. ES also occurs as a primary soft tissue neoplasm without involvement of bone. We report the second case of extraosseous (EO) ES emerging from the omentum and a review of the relevant literature. EO ES should be included in the differential diagnosis of soft tissue neoplasms in the abdomen
