Pulmonary sequestration is a very rare congenital malfomation, especially when it is located in the infradiaphragmatic retroperitoneal space. The patient was a 56-year-old man with no respiratory symptom but had some postprandial epigastric discomfort for several days. Plain chest x-ray revealed mild elevation of left diaphragm and abdominal CT scan showed large cystic retroperitoneal mass with some calcification. We performed the operation through the thorachoabdominal incision and the mass was proven to be a pulmonary sequestration. Therefore, we report the case with review of literatures.

Retroperitoneal pulmonary sequestration is an extremely rare congenital malformation. It is more frequently diagnosed in the antenatal period due to routine ultrasonic examinations that are conducted for a fetus or during the first 6 months of life, although retroperitoneal pulmonary sequestration is incidentally discovered in adults on rare occasions. Because the location and radiological findings of retroperitoneal pulmonary sequestration are very similar to those of another retroperitoneal masses, retroperitoneal pulmonary sequestration, although they are very rare, should be included in the differential diagnosis of a retroperitoneal suprarenal mass. Although fine needle aspiration may be considered as an aid for making the preoperative diagnosis, surgery remains the treatment of choice for symptomatic lesions and this surgery is associated with excellent results and a good prognosis.

Urinothorax occurs when urine leakes into thoracic cavity and it was first reported by Correie in 1968. The mechanism of its occurrence is an accumulation of urine in thoracic cavity by retroperitoneal urinoma formed by urinary tract obstruction or trauma. Retroperitoneal inflammation, malignant neoplasm, kidney transplantation, and kidney biopsy can also induce urinothorax. The diagnosis of urinothorax may be delayed due to its rare incidence rate, but if diagnosis is confirmed the treatment is possible by urinary diversion. We report our experience of a case of urinothorax associated with retroperitoneal urinoma followed by blunt renal trauma with review of literatures.

Immunoglobulin G4 (IgG4)-related disease is a systemic disease characterized by dense lymphoplasmacytic infiltrates with abundant IgG4-positive plasma cells and fibroblast proliferation. The retroperitoneal involvement of IgG4-related disease usually appears as a soft-tissue mass covering the abdominal aorta or entrapping the ureters, resulting in hydronephrosis. Here, we present a case of IgG4-related disease with retroperitoneal involvement in a 75-yearold woman with an unusual manifestation. A preoperative computed tomography (CT) scan revealed an irregular infiltrative retroperitoneal mass invading the normal anatomic barriers, raising the suspicion of malignancy or inflammation. Contrast-enhanced CT revealed a homogeneous progressive enhancement of the mass.

Bronchogenic cysts are usually located in the pulmonary parenchyma or in the mediastinum. When bronchogenic cysts are located in the mediastinum, they are usually near the bronchus or esophagus, and rarely located in the retroperitoneal space. It is difficult to differentiate between bronchogenic cysts and benign cysts prior to surgert. We report here on a patient for who had a mass in the retroperitoneum, with the preoperative diagnosis being a benign neurogenic tumor. Via left open thoracotomy, pathologic reports revealed that the mass was a bronchogenic cyst. We report here on the case of a bronchogenic cyst that was located in the retroperitoneal space of the diaphragm.

Retroperitoneal hemorrhage is a potentially lethal complication in patients on anticoagulant therapy and can be caused by ovarian artery bleeding, regardless of the patients' age and obstetric history. This case illustrates the clinical presentation of ovarian artery bleeding in a postmenopausal female on anticoagulant therapy, the diagnostic utility of transcatheter angiography, and successful embolization.

We have experienced 2 patients who underwent retroperitoneal endoscopic lumbar sympathectomy(RELS) for bilateral plantar hyperhidrosis. They had underwent thoracic sympathectomy by thoracoscopy 20 months and 1 month ago, respectively. The first patient had to be converted to the open procedure due to pneumoperitonium and she was reoperated due to continous sweating by the incomplete sympathectomy on right side. At follow-up after 70 and 30 days postoperatively, RELS results were graded as excellent, good, fair, or poor. The first patient was very satisfied as "Excellent" and the second was slightly less satisfied as "Good" with compensatory hyperhidrosis at perianal area. This RELS is a feasible procedure to plantar hyperhydrosis patients with less pain, minimal scar, short period of convalescence, and short hospital stay.short hospital stay.

Acupuncture is increasingly being used in Asian countries and is generally considered a relatively safe procedure. However, adverse events have been reported consistently. Therefore, clinicians should be aware of the possibility of acupuncture-related complications and should actively treat serious cases. We report a case of an acupuncture-induced large abscess in the retroperitoneal cavity and thigh muscles treated with percutaneous catheter drainage, surgical incision, and drainage.

A case of paraganglioma of the retroperitoneum diagnosed by fine needle aspiration cytology is described. A 60-year-old man presented with abdominal discomfort for 4 months. The smear revealed cellular sheets with partly rosettoid appearance. Many piexiform capillaries were distributed between the cellular sheets or encircled the cellular nests forming zell-ballen pattern. The tumor cells were monotonous and oval to round. The cytoplasm was amphophillc, finely granular and poorly defined. The nuclei were round and had evenly dispersed chromatin and small nucleoli. Cells having large or spindle nuclei were some-times observed. The tissue sections showed typical findings of paragnglima. The cytological differential diagnoses included islet cell tumor of the pancreas and carcinold tumor. The clinical and histoloigic findings as well as cytologic findings were helpful to confirm the diagnosis.
