Retroperitoneal fibrosis (RPF) is a rare disease characterised by fibrous tissue proliferation in the retroperitoneum, with encasement of the ureters and large vessels of the abdomen as the most destructive of potentially severe complications. It can either be idiopathic, or secondary to infections, malignancies, or the use of certain drugs. The idiopathic form accounts for approximately 75% of the cases, and is usually responsive to immunosuppressive therapy. In recent years, the emergence of a new clinical entity, IgG4-related disease (IgG4-RD), shed light on many fibro-inflammatory disorders once thought to be separate clinical entities, although frequently associated in the so-called multifocal fibrosclerosis...

INTRODUCTION: We employed a safe approach during laparoscopic splenectomy by first mobilizing the pancreatic tail and then dissecting the splenic vessels at the splenic hilum before mobilizing the spleen. MATERIALS AND SURGICAL TECHNIQUE: Patients were placed in the lithotomy position, and only the upper body was twisted to the right side. Five trocars were placed. After the bursa omentalis was opened, an avascular layer was identified behind the pancreas. This avascular layer was bluntly dissected, and the pancreatic tail was isolated from the retroperitoneum...

Insulin-like growth factor 2 is overexpressed in various cancers, and is associated with a poor prognosis. Also, it is known that insulin-like growth factor 2 is an etiology of non-islet cell tumor hypoglycemia. In this report, we describe a case of unexpected hypoglycemia caused by a dedifferentiated liposarcoma producing insulin-like growth factor 2. A large mass in the retroperitoneum was detected in a 61-year-old man who complained of appetite loss. Despite having no history of diabetes mellitus, hypoglycemia suddenly occurred after admission, but oral glucose therapy was ineffective...

Sibabrata Kar, Vandana Mohapatra, Pratap Kumar Rath
Primary internal hernias are extremely rare in adults. They are an important cause of small intestinal obstruction and lead to high morbidity and mortality if left untreated. Clinical presentation of internal hernia is nonspecific. Imaging has been of limited utility in cases of acute intestinal obstruction; moreover, interpretation of imaging features is operator dependant. Thus, internal hernias are usually detected at laparotomy and preoperative diagnosis in an emergency setting is either difficult or most of the time not suspected...

BACKGROUND: It is common knowledge that high ligation of blood vessels at the D3 level and complete mesocolic excision (CME) are two critical points of right hemicolectomy for right colon cancer (RCC). (1-5) To date, a safe strategy for completing these two procedures under laparoscopic surgery has not been extensively described. The authors provide a video to demonstrate laparoscopic right hemicolectomy (D3 + CME) with an optimal mesentery-defined approach. By identifying three "tri-junctions," this approach facilitates dissection of the entire mesocolon along the embryologic planes as far centrally as possible and enables the high tie of feeding vessels at bifurcation...

Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor that usually occurs in soft tissues of the extremity and rarely in the retroperitoneum. We report a unique case of isolated massive fetal ascites attributed to KHE, involving the retroperitoneum and multiple visceral organs, along with the Kasabach-Merritt phenomenon. We suspect that retroperitoneal KHE might have caused massive fetal ascites because of its high potential to invade the lymphatic vessels aggressively in the retroperitoneal space, which possibly permits intestinal lymph leakage into the peritoneal cavities...

Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, usually arises in the extremities and retroperitoneum. Primary laryngeal undifferentiated pleomorphic sarcoma is very rare, with only 63 cases having been reported in the literature as of 2015. The disease has a poor prognosis because of problems with local recurrence and metastasis. Wide resection has been recommended as a treatment modality in previous reports. We report a case of undifferentiated pleomorphic sarcoma of the vocal fold in a 64-year-old man presenting with rapid growth...

Leiomyoma of deep soft tissue is an unusual entity reported in less than 60 cases in the English literature. The lesion is now accepted as a rare neoplasm. Leiomyomata of deep soft tissue have been divided into 2 groups, those occurring primarily in women in the retroperitoneum, histologically similar to leiomyomata of the uterus, and those occurring equally in both sexes in the somatic deep soft tissues. Irrespective of location, these lesions can demonstrate calcification, and even less commonly ossification...

We present the case of a 52-year-old woman who presented to the emergency department with chest and neck pain. Initial cervical spine magnetic resonance imaging shows an abnormal flow void in the left vertebral artery, which prompted a computed tomographic angiogram. This demonstrated a hyperdense thickened ascending aortic wall, which extended into the great vessel origins. Clinically and radiographically interpreted as an acute aortic syndrome and/or intramural hematoma, the patient underwent ascending aortic repair with graft...

: Erdheim-Chester disease is a histiocytic neoplasm of diseases from the group of non-Langerhans-cell histiocytoses, formed by infiltrates of foamy histiocytes. These pathological histiocytes produce pro-inflammatory cytokines. Therefore Erdheim-Chester disease is called inflammatory histiocytary neoplasm. The disease is accompanied by clinical symptoms of systemic inflammatory response, i.e. B symptoms. Imaging examinations detect typical osteosclerotic changes affecting diaphyses and metaphyses of the lower long bones and fibrotic changes which affect the aorta wall and the vessels leading from it...

Pleomorphic Hyalinizing Angiectatic Tumor (PHAT) is a rare benign lesion characterized by slow growth, infiltrative behavior and high rate of local recurrences. Only one case has been described in retroperitoneum, at renal hilum, but not involving pelvis or parenchyma. Here we present the first case of PHAT arising in the renal parenchyma. A nodular lesion in right kidney lower pole was diagnosed to a 61 year old woman. The patient underwent right nephrectomy. Microscopically, the lesion showed solid and pseudo-cystic components with hemorrhagic areas characterized by aggregates of ectatic blood vessels...

In 2005, a 48-year-old man with a spinal cord injury had an inferior vena cava filter placed for recurrent deep vein thrombosis and pulmonary embolism. He was referred for filter retrieval after a computed tomography scan demonstrated caval stenosis and 2 fractured filter arms, 1 in a pulmonary artery and 1 penetrating into the retroperitoneum and impinging on the aorta. During retrieval, 1 arm was inadvertently advanced into the aorta, and embolization of the arm occurred to the left profunda femoris artery...

The IgG4-associated diseases of connective tissue are caused by allergen-mediated autoimmune processes. The retroperitoneum, mesentery and mediastinum as well as other less common localizations, such as the neck, orbit and periarticular connective tissue can be affected. Inflammatory fibrosis is initially dominated by a lymphocytic and plasma cell-rich infiltrate and later by cell-poor storiform fibrosis. Stenosis and occlusion of vessels, ureters and intestines can cause severe complications. Computed tomography (CT) and magnetic resonance imaging (MRI) can be implemented in the diagnostic algorithm to narrow the differential diagnosis, delineate the distribution of fibrosis and reveal complications...

Growing teratoma syndrome is an infrequent presentation of testicular cancer. We present a case of growing teratoma syndrome in a patient who initially presented with clinical stage I nonseminomatous testicular germ cell tumor, who subsequently developed large volume oligometastases to the retroperitoneum, thorax, and thigh. Despite two regimens of chemotherapy, his disease progressed. Complete surgical extirpation of all gross tumors confirmed mature teratoma. An aggressive surgical approach, including postchemotherapy resection of all known metastatic sites, can provide long-term disease-free survival...
