Retroperitoneal cyst

Koy Min Chue, Giap Hean Goh, Alfred Wei Chieh Kow
Adrenal pseudocysts are rare entities, which are usually asymptomatic. Large symptomatic adrenal pseudocysts may cause compressive symptoms. The etiology of these cysts is unknown, although the cyst wall is all lined by fibrous tissue, without any epithelial or endothelial lining. We report a case of a 26-year-old lady who presented with a symptomatic right adrenal pseudocyst measuring 7.6 cm in size. Magnetic resonance imaging confirmed the presence of a right retroperitoneal cystic lesion which was hyperintense on T2 sequencing...

RATIONALE: Cystic echinococcosis (CE) is a parasitic zoonosis caused by echinococcus larvae. Manifestations of the disease include a severe damage to the liver and lung. Damages to the mesentery, omentum, spleen, brain, heart, bone, thyroid, kidney, and uterus are rarely observed. Moreover, primary ovarian and retroperitoneal hydatid disease is extremely rare, and is easily ignored or misdiagnosed. PATIENT CONCERNS: We present a case of CE in a 34-year-old female who presented with an adnexal mass detected by B-ultrasound...

Retroperitoneal tumor is a rare tumor, with an incidence of 0.2 to 0.8%. Among such tumors, the frequency of teratomas ranges from 6 to 18%, and adult cases are extremely rare. We report a mature teratoma that occurred in the retroperitoneum of 43-year-old woman. She experienced back pain and a left adrenal gland mass was detected on computed tomography. Computed tomography and magnetic resonance imaging findings showed a cyst made of fat and calcification, but it was difficult to distinguish retroperitoneal teratoma from adrenal tumor in this case...

Cellular angiofibroma is a mesenchymal tumor, described in 1997, without gender preference, that usually appears at age 40. The vulvovaginal area is the most common site in women, mimicking vulvar benign tumors, like Bartholin gland cyst. However, there are a few described cases of a deep or extra-pelvic angiofibroma. Excision is the treatment of choice and the recurrence rate appears to be low. We present the case of a woman with a heterogeneous tumor in the right adnexial region. At the surgery, a retroperitoneal tumor was excised and the histopathological tissue analysis revealed a cellular angiofibroma...

Renal angiomyolipoma (AML) is an uncommon renal tumour, generally composed of mature adipose tissue, dysmorphic blood vessels and smooth muscle. Identification of intratumoral fat on unenhanced CT images is the most reliable finding for establishing the diagnosis of renal AML. However, AMLs sometimes exhibit atypical findings, including cystic as well as solid forms; some of these variants overlap with the appearance of other renal tumours. A rare type of AML, the epithelioid type, possesses malignant potential...

BACKGROUND: To determine whether MRI feature analysis can differentiate benign retroperitoneal extra-adrenal paragangliomas and schwannomas. METHODS: The MRI features of 50 patients with confirmed benign retroperitoneal extra-adrenal paragangliomas and schwannomas were retrospectively reviewed by two radiologists blinded to the histopathologic diagnosis. These features were compared between two types of tumours by use of the Mann-Whitney test and binary logistic regression...

A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion. During surgery, a mass was observed only in the left ovary with no invasive growth, but adhesions to the surrounding peritoneum were seen. Given the patient's age, large mass size, and accompanying uterine myoma and right ovarian cyst, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed...

The complications of autosomal dominant polycystic kidney disease (ADPKD) include cyst rupture and haemorrhage leading to loin pain and frank haematuria. Risk factors include large kidney volume, hypertension, and renal impairment. We present a case of a young male who, following trauma to the kidney, had a life threatening bleed from his polycystic kidney. The case was initially treated with fluid resuscitation and blood transfusion but necessitated radiological embolization of bleeding source to control the blood loss...

BACKGROUND: Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is extremely rare, and its biological behavior, pathogenesis, optimum treatments, and prognosis remain to be elucidated. We herein report a case of PRMC with an 80-month follow-up. CASE PRESENTATION: A 29-year-old woman was diagnosed with unknown retroperitoneal tumor with benign right ovarian cyst and uterine fibroids, and she underwent laparotomy. The tumor was completely resected with a subsequent histopathological diagnosis of primary retroperitoneal mucinous cystadenocarcinoma (PRMC)...

Hypertension is a prevalent disease in developed countries. Adrenal masses, and especially adrenal cysts, are a rare and usually asymptomatic finding, which can go unnoticed or be detected as incidental findings in imaging tests. These circumstances make the multidisciplinary approach mandatory. The case is presented on a 72 year-old woman with uncontrolled high blood pressure referred to the Urology Department due to the incidental finding of a right retroperitoneal mass. A functional and imaging study was performed, establishing a diagnosis of adrenal cyst causing hypertensive symptoms...

BACKGROUND: To assess the safety and efficacy of laparoscopic retroperitoneal resection for retroperitoneal lymphatic cysts. METHODS: A retrospective analysis was conducted based on clinical data from eight patients with hydronephrosis caused by retroperitoneal lymphatic cysts. All patients underwent laparoscopic retroperitoneal lymphatic cyst resection and received postoperative follow-up. A follow-up ultrasound was performed postoperatively every 6-12 months to evaluate the recovery of the hydronephrosis...

A 37-year-old woman with the complaint of stomachache was referred to our hospital because a retroperitoneal tumor was detected in an ultrasound study at another hospital. Magnetic resonance imaging showed a poorly enhanced 14 cm tumor in the left retroperitoneal space suggesting a cyst that contained fat and showed calcification. Abdominal dynamic computed tomography revealed left renal vein stenosis and left ovarian vein dilation caused by tumor compression of the renal vein. The tumor was excised together with the left kidney because the renal vein was adhered to the tumor...

Benign intra-abdominal cystic masses in infancy are fairly uncommon and their etiopathogenesis, histology and clinical presentation differ significantly. Our aim is to report our experience in their treatment in order to discuss the best diagnostic and treatment modality. The medical records of 5 children (2M, 3F) with cystic intraabdominal masses referred to our hospital between November 2012 and September 2016, were retrospectively reviewed. All patients underwent open surgery and subsequent histopathologic analysis...

Treatment options for simple renal cyst (SRC) include open surgery, laparoscopy with decortication, or percutaneous aspiration with or without sclerotherapy. Though laparoscopic unroofing achieves better results than percutaneous sclerotherapy, the reported recurrence rate is still up to 19%. Thus, it is necessary to find methods to reduce the recurrence rate.To investigate whether the perirenal pedicled fat tissue wadding technique during retroperitoneal laproscopic deroofing (RLD) of SRC affects the incidence of recurrence...

Metastatic primary testicular carcinoid tumor remains a very rare condition. We report the first case of metastatic primary testicular carcinoid tumor where along retroperitoneal lymph node dissection excision of the Inferior Vena Cava was also performed. The rarity is further emphasised by the presence of a contralateral testicular dermoid cyst. Given the features of the tumor were not in keeping with the traditional predictors of metastases (primary tumor >7.3 cm, poor differentiation and the presence of carcinoid syndrome) this case adds valuable addition to the relatively limited literature available on this rare condition...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

Retroperitoneal cysts are not common. Primary retroperitoneal cysts are essentially benign in nature. Mostly, they are detected incidentally. At times, they may attain a huge size and may present with large abdominal lump. In our case, a 55-year-old man had a left-sided large idiopathic retroperitoneal cyst, for which complete curative excision was performed.
