BACKGROUND: Traditional approaches for retroperitoneal lumbar plexus schwannomas involve anterior open or laparoscopic resection. For select tumors, the lateral retroperitoneal approach provides a minimally invasive alternative. OBJECTIVE: To describe a minimally invasive lateral transpsoas approach for the resection of retroperitoneal schwannomas. METHODS: A lateral retroperitoneal transpsoas approach was used to resect a 3.1 × 2.7 × 4...

BACKGROUND: We report a case of a giant retroperitoneal calcifying fibrous tumor (CFT) treated by radical tumor resection combined with right hepatectomy and reconstruction of the inferior vena cava (IVC) and bilateral renal veins. Only three case reports of CFT arising in the retroperitoneum have been reported until today. CASE PRESENTATION: In a 19-year-old female patient, computed tomography (CT) images showed a well-demarcated expansile lesion around the IVC accompanied by focal calcification, whereas the IVC that was circumferentially surrounded by the lesion was dilated due to the desmoplastic reaction...

Georges Nasrallah, Fouad G Souki
PURPOSE OF REVIEW: Laparoscopic kidney surgery is commonly used for living donor, partial, and total tumor nephrectomy. The successful emergence of laparoscopic technique was justified by the many benefits offered such as reduced blood loss, tissue trauma, pain, and hospital stay. However, this comes at the expense of physiologic changes and complications secondary to pneumoperitoneum, surgical technique, and patient positioning with significant challenges in anesthetic management. RECENT FINDINGS: A variety of laparoscopic approaches (transperitoneal, retroperitoneal, hand-assisted, robotic) are used with some having advantages over others...

Background/Aims/Objectives: Various nephron-sparing approaches were described as part of surgical management for Fraley's syndrome, a rare anatomic variant of the renal vascular anatomy that compresses the upper pole infundibulum resulting in an upper calyceal obstruction and dilatation, with symptoms of flank pain and hematuria. To date, descriptions of minimally invasive correction techniques are anecdotal. METHODS: A retroperitoneal pure laparoscopic approach using the nephron-sparing technique was chosen in the presented case...

Retroperitoneal haematomas in obstetrics are uncommon. The causes and pathogenesis of retroperitoneal haematomas lack clarity and the aim of this review is to recognise retroperitoneal haematomas as a separate entity from commonly seen vaginal and pelvic haematomas. It is time to raise awareness among obstetricians to recognise retroperitoneal haematomas as an important cause of maternal morbidity and mortality which requires high clinical suspicion and multidisciplinary input. As retroperitoneal haematomas are rare but can cause serious threat to maternal wellbeing, resources should be directed towards their management...

The simultaneous presence of renal angiomyolipoma and oncocytoma is a rare occurrence. Extrarenal retroperitoneal angiomyolipoma is an even more rare neoplasm, and its simultaneous presence with renal oncocytoma has not been documented. We present herein the first case to be reported in English literature.

A child with bilateral familial retinoblastoma underwent staging MRI brain and orbit which identified subtle leptomeningeal enhancement, thus prompting an MRI whole body, which revealed a retroperitoneal mass, confirmed on laparoscopic biopsy to be neuroblastoma. This is the first reported case of these two rare embryonal non-central nervous system tumors occurring concurrently. The cause of this concurrence is unknown despite their pathogenic similarities with a chance of 4 cases per 10 billion children aged 1-4 years...

Synovial sarcoma is a ubiquitous neoplasm predominantly affecting soft tissues of young adults of any gender; few cases have been described in the digestive system, mostly in the stomach. The (X;18)(p11.2; q11.2) translocation yields unique SS18-SSX fusion genes. Synovial sarcoma has been related to radiotherapy, but no synovial sarcoma has been associated with the digestive system. This article describes the case of a synovial sarcoma arising along the extrahepatic biliary tree, 10 years after the application of an abdominal radiotherapy schedule due to a retroperitoneal metastatic seminoma in a male who developed progressive obstructive jaundice...

REVIEW

Retroperitoneal sarcomas are rare tumors of which liposarcoma is the most common histology. Surgical resection remains the mainstay of therapy, particularly for the well-differentiated subtype. They can grow to massive size before causing symptoms or detection. Well-differentiated liposarcoma, while having a negligible metastatic rate, is fraught with a high local recurrence rate, despite a complete surgical resection. Reasons for this are not completely known but may be related to a field defect of the retroperitoneal fat creating a niche for recurrence...

Lipoblastoma is part of tumors derived from adipose tissue. It is a benign neoplasm that can be localized or diffuse, affecting children in early childhood and usually located in the trunk and extremities. These tumors are uncommon in the pediatric age, but when one of them is present, it is a challenge that we must resolve quickly due to the risk of malignancy that involves other similar neoplastic lesions. The preoperative diagnosis is difficult, because the imaging methods do not provide specific information that allows us to differentiate them from other tumors, such as liposarcomas...

BACKGROUND: The posterior retroperitoneoscopic adrenalec tomy has several advantages compared with the transperitoneal approach such as a shorter and more direct route to the target organ, no breach of the intraperitoneal space, and no required retraction of the adjacent organs. It also is a safe procedure with a short learning curve.1-5 This report presents a challenging case of an extra-adrenal paraganglioma located in the aorto-caval space and managed using the retroperitoneal approach...

Renal angiomyolipoma (AML) is an uncommon renal tumour, generally composed of mature adipose tissue, dysmorphic blood vessels, and smooth muscle. Identification of intratumoural fat on unenhanced CT images (UECT) 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...

Failure to thrive (FTT) is a state of overall decline. Patients often present with weight loss, poor appetite, malnutrition, and decreased physical functioning. The etiology is multifactorial including chronic diseases, functional impairments, and acute illnesses. Evaluation for reversible causes is paramount, and treatment is aimed at maintaining or improving functional status. We present a case of a 91-year-old woman with a retroperitoneal mass that was found on workup for failure to thrive.

OBJECTIVE: Nephrostomy tubes (NT) inserted in emergency settings by interventional radiologists are frequently unsuitable for subsequent percutaneous nephrolithotomy (PCNL). We report a novel method of adjusting these NTs to be used as PCNL tracts and avoid renal re-puncture. PATIENTS AND METHODS: A retrospective search of 981 consecutive PCNLs performed in our institution between 2002-2017 identified all patients with preoperatively inserted NTs. The NTs unsuitable for PCNL were adjusted by a novel approach in which a 5-mm incision was made at the ideal puncture location (IPL) as indicated under fluoroscopic guidance...

OBJECTIVES: In advanced epithelial ovarian cancer (AOC), lesser sac (LS) metastasis particularly to the supragastric LS (SGLS) may be overlooked, resulting in unrecognized residual disease. We aimed to identify the frequency, distribution, and predictors of LS metastasis using laparoscopic evaluation at laparotomy and perioperative surgical complications associated with evaluation and resection/ablation. METHODS: Prospective observational study in consecutive patients with AOC undergoing laparotomy for primary or interval cytoreductive surgery in 2 centers between November 2013 and December 2016...
