An 11-year-old spayed female maltese was presented for abdominal distention, dysuria and dyschezia. Panting and heart murmur was found and abdominal palpation was difficult due to increased abdominal pressure. A soft tissue mass, $6{\times}3cm$ in size, was identified radiographically in pelvic canal, displacing the descending colon to the medioventral direction and the urinary bladder cranially. On ultrasonography, the mass consisted of homogeneous hypoechoic parenchyma containing the focal hyperechoic region ($1.6{\times}1.5cm$). The mass had distinct margin and no connection with adjacent organs. It was considered as a mass originating from the retroperitoneal cavity. Additional diagnostic procedures were not advanced because of the owner's request, and only a surgical excision of the mass was performed to alleviate the dysuria and dyschezia. Histopathologic examination and immunohistochemistry determined the mass as a soft tissue sarcoma and excluded hemangiosarcoma and osteosarcoma, both are the most common types of the retroperitoneal tumors. This report described non-vascular soft tissue sarcoma originating from the retroperitoneal cavity in a maltese dog.

Retroperitoneal teratoma was described in a 20-month-old intact female ferret (Mustela putorius furo). Retroperitoneal mass about $8{\times}5$ cm in size was surgically removed and histopathologic examination was performed. Grossly, on cross section of the mass, the consistency was soft to firm and contained several cystic structures which are filled with dried keratinous material. Histologically, the retroperitoneal mass consisted of embryologically heterogeneous tissues that include skin, bone and cartilage, adipose tissue, respiratory epithelium, and exocrine pancreatic tissue. Based on the characteristic histologic features of the mass, a diagnosis of retroperitoneal teratoma was made. Adrenal gland or ovary was suspected as the origin of the tumor.

Spinal extradural arachnoid cysts usually cause symptoms related to spinal cord or nerve root compression. Here, we report an atypical presentation of a spinal extradural arachnoid cyst combined with congenital hemivertebra which was presented as a retroperitoneal mass that exerted mass effects to the abdominal organs. On image studies, the communication between the cystic pedicle and the spinal arachnoid space was indistinct. Based on our experience and the literature of the pathogenesis, we planned anterior approach for removal of the arachnoid cyst in order to focus on mass removal rather than ligation of the fistulous channel. In our estimation this was feasible considering radiologic findings and also essential for the symptom relief. The cyst was totally removed with the clogged 'thecal sac-side' end of the cystic pedicle. The patient was free of abdominal discomfort by one month after the surgery.

A 35-year-old woman, previously treated for systemic metastases from retroperitoneal yolk sac tumor, presented with progressive painful paraparesis. Preoperative images showed severe cord compression by the metastatic infiltration of the lumbar vertebrae and epidural mass as well as a huge retroperitoneal mass. While performing unremarkable surgery in prone position, the patient abruptly fell into hypoxic insults and circulatory arrest. Intraoperative pulmonary tumor embolism was deemed a cause of death. When planning operative procedure for this dangerous malignancy, scrupulous manipulation is mandated and the possibility of fatal pulmonary tumor embolism should also be addressed and fully discussed preoperatively.

Benign metastasizing leiomyoma (BML) is a rare disease, which usually occurs in women with a history of a prior hysterectomy or myomectomy for benign uterine leiomyoma, and has the potential to metastasize to distant sites, such as the lung, lymph nodes, muscular tissue, heart, or retroperitoneum. These lesions are slow-growing, asymptomatic, and usually found incidentally. The prognosis of BML is also excellent. However, there has been debate on the origin and the correct classification of BML, and there are no guidelines for the treatment of BML. We report here on a rare case of BML in both the retroperitoneal cavity and lung in a 48-year-old woman with a history of hysterectomy due to histologically benign uterine leiomyoma. The patient underwent retroperitoneal mass excision and bilateral salpingo-oophorectomy, and then wedge biopsy of two pulmonary nodules was performed additionally 9 days later. Until now, there has been no sign of recurrence and the patient remains asymptomatic. To our knowledge, pulmonary BML is rare and the co-existence of the retroperitoneal metastases after previous hysterectomy is even rarer.

횡격막하 후복막강에 발생한 폐격리증은 매우 드문 선천성 기형으로 증상없이 우연히 발견되는 경우가 많으며 호발부위 위치상 다른 부신옆 종양들과 감별을 요하며 외과적 절제술로 치료된다. 저자들은 국내에서 아직 보고되지 않은 횡격막하 후복막강 폐격리증을 1례 경험하였기에 보고하는 바이다.

후복막 낭성 림프관종은 양성종양으로 매우 드문 질환이다. 수술적 절제가 원칙이나, 경화요법을 우선적으로 고려할 수도 있다. 9세 남자가 병원 방문 4일 전부터점점 심해지는 복통을 주소로 입원하였다. 혈색소 농도가 입원 당일 12.8 g/dL에서, 입원 3병일째 10.6 g/dL로 감소한 소견이 있었다. 복부 전산화 단층촬영에서 크고 종양내부에 격막이 있는 분엽상의 후복막 낭종($10{\times}9.5{\times}5cm$) 한 개가 좌측 신장 주위 공간에서 관찰되었다. 종양 내부에는 출혈이 동반되어 있었으며, 하장간막정맥이 종양에 의해 둘러싸여져 있었다. 수술적 치료의 위험도가 매우 높을 것으로 판단되어 낭종조영술을 시행하였고, 경피적 도관 배액술과 에탄올 경화요법을 시행하였다. 추적 검사로 시행한 복부 전산화 단층촬영에서 종양의 크기가 현저히 감소된 소견을 보였다. 환자는 퇴원 후 13개월 째 현재까지 낭종의 재발없이 건강하게 지내고 있다. 결론적으로, 수술적 치료의 위험이 높은 후복막 낭성 림프관종이 있는 경우 경피적 도관 배액술과 경화요법을 우선적으로 고려해야 할 것이다.

후복막강 폐격리증은 극히 드문 질환으로 보통은 임신 6개월경에 시행하는 태아 초음파로 발견되며 드물지만 성인에서 우연히 발견된다. 후복막강 폐격리증은 그 위치와 방사선학적인 소견이 신경아세포종 등의 다른 후복막강 종괴와 아주 유사하기 때문에 그 발생 빈도가 극히 드물더라도 후복막강 종괴가 의심될 때 감별을 요한다. 세침 흡입 검사가 수술 전 진단에 도움이 된다고 하지만, 수술적 제거가 환자의 예후나 경과를 생각 했을때 좋은 치료 방법이라고 생각된다.

An eight-year-old, 3.4 kg, spayed female poodle dog was referred to Gyeongsang National University Animal Medical Center with obstinate bilateral retroperitoneal subcutaneous abscess. The medical history revealed ovariohysterectomy (OHE), lipoma, and mammary gland tumor excision performed two years ago. The dog presented with left retroperitoneal subcutaneous abscess discharge five months back and was treated by abscess drainage and antibiotics in a local veterinary hospital, but a relapse was reported on discontinuing antibiotics. On physical examination, the dog was febrile (40℃) and both retroperitoneal masses showed typical inflammatory reaction and purulent discharge. On serum chemistry analysis, hyperproteinemia, hyperglobulinemia, and elevated levels of C-reactive protein were observed. Cytologic examination showed degenerative neutrophils and phagocytic macrophages. Radiological examination revealed encapsulated hypoechoic subcutaneous masses in bilateral abdominal flank and the left flank mass was connected with the caudal pole of left kidney through fistula. Based on the diagnostic examination, exploratory celiotomy was recommended and left nephrectomy, and resection of bilateral masses were performed. During procedure, fistula between caudal pole of left kidney and left subcutaneous abscess was detected and suture material was identified. Resected tissue was histologically examined and diagnosed as suppurative abscess caused by the suture material. This case report describes chronic suppurative foreign body reaction including caudal pole of left kidney and bilateral retroperitoneal subcutaneous masses induced by the suture material used in OHE two years ago and the necessity of computed tomography examination to identify character of mass and extent of surgical resection.

원발성 후복막 점액낭샘암종은 매우 드문 질환으로 현재까지 전 세계적으로 51예가 보고 되었고 이 중 임산부에서 발생한 사례가 3예 있었다. 저자들은 31세 여성에서 임신 15주 3일에 발견된 원발성 후복막 점액낭샘암종의 자기공명영상 소견을 보고하고자 한다. 복부 자기공명영상에서 후복막강 내에 위치한 종괴는 경계가 좋은 낭종으로 불규칙하게 두꺼워진 낭벽과 내부에 중벽을 가지고 있으며, T1강조영상과 T2강조영상에서 다양한 신호강도를 보이는 부위를 포함하고 있었다. 수술을 통해 원발성 후복막 점액낭샘암종으로 진단 받았고 수술 15개월 후 양측 난소에 전이성 점액낭샘암종이 발생하여 전자궁적출술과 양측 난소난관절제술 및 대망절제술을 시행하였다.
