We report a unique case of intestinal duplication detected on posterior reversible encephalopathy syndrome (PRES) in a 13-year-old girl. She was admitted to the pediatric Emergency Department because of generalized seizures. Radiological assessment revealed a large, well-defined, thick-walled cystic lesion in the mid abdomen, suggestive of duplication cyst associated to a PRES. Exploration confirmed the diagnosis of ileal duplication cyst, and the mass was resected. The postoperative course was uneventful. Both hypertension and neurological dysfunction resolved after the mass resection...

INTRODUCTION: Desmoid-type fibromatosis represents a rare, benign, soft tissue tumour that is locally invasive with high recurrence potential. PRESENTATION OF CASE: We encountered a case of retroperitoneal desmoid-type fibromatosis in a 45-year-old woman who presented with chief complaints of stomach ache and vomiting. She underwent total abdominal hysterectomy and left salpingo-oophorectomy due to uterine myoma and a paroophoritic cyst at 42 years of age. Abdominal computed tomography showed a 5-cm left retroperitoneal tumour and severe hydronephrosis of the left kidney...

INTRODUCTION: Prepubertal testicular tumors are fundamentally distinct from their postpubertal and adult counterparts. Racial and ethnic differences contribute to the incidence, characteristics, and histological distribution of prepubertal testicular germ cell tumors (PTGCTs). OBJECTIVE: To elucidate the characteristics and treatment outcomes of PTGCTs in a Chinese cohort. STUDY DESIGN: Data were retrospectively reviewed from consecutive PTGCT patients aged <12 years who received treatment at the current institution from January 2007 to December 2015...

BACKGROUND: The deep location, narrow operative space and proximity to major vessels make minimally invasive resection of nonadrenal retroperitoneal tumors (NTRs) challenging and rarely reported. This study aimed to evaluate the safety and feasibility of robotic resection of benign nonadrenal retroperitoneal tumors. METHODS: The demographics and perioperative outcomes of a consecutive series of patients who underwent robotic NTR resection between January 1, 2015, and August 30, 2017, were analyzed...

INTRODUCTION: Duplication cysts are very rare congenital malformations in adults. They are lined by gastrointestinal mucosa, connect to the digestive tract, and share smooth muscular layers and a common blood supply. In rare cases, duplication cysts are completely isolated from the digestive tract and have a proper blood supply. Completely isolated duplication cysts in the retroperitoneum are unusual so it is hard to diagnose them without a surgical resection. PRESENTATION OF CASE: A 19-year-old male presented at our emergency department with sharp abdominal pain...

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...

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...

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...

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...

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...
