Retroperitoneal cyst

The main challenges of imaging for endometriosis are the detection of nonovarian disease and the evaluation of the extension of the disease into pelvic structures. Transvaginal ultrasonography (TVS) has been proposed as the first-line imaging technique because it allows extensive exploration of the pelvis. The "typical" endometrioma is a unilocular cyst with homogeneous low-level echogenicity (ground glass echogenicity) of the cyst fluid. The use of color Doppler helps avoid classifying malignancies as endometriomas, defining the presence of vascular flow in papillations...

Adrenal hemangioma is an uncommon benign vascular tumor that is often discovered incidentally. It has never been reported in association with familial adenomatous polyposis. We report a case of a 60-year old man with a history of familial adenomatous polyposis, in whom a huge retroperitoneal cyst of 18x17 cm was discovered during routine radiologic evaluation. Because of the impossibility of ruling out the presence of malignancy, surgical cystectomy was performed, associated to a scheduled total colectomy. Pathological examination revealed that the cyst corresponded to an adrenal cavernous hemangioma...

: Hemorrhagic rupture is a very rare complication of a simple hepatic cyst. We report the first case of a totally extraperitoneal rupture of a recurrent cyst, occurred in a 73-year-old man who presented with acute right hypochondralgia. Computed tomography revealed the rupture of a large hemorrhagic cyst in the right liver lobe and the formation of a voluminous hematoma in the retroperitoneal space. Despite the absence of hemoperitoneum, the entity of the bleeding led us to perform an urgent and successful surgical intervention...

BACKGROUND: Coccygodynia is a pain in the region of the coccyx that radiates to the sacral, perineal area. The cause of the pain is often unknown. Coccygodynia is diagnosed through the patient's past history, a physical examination, and dynamic radiographic study, but the injection of local anesthetics or a diagnostic nerve blockade are needed to distinguish between somatic, neuropathic, and combined pain. Ganglion impar is a single retroperitoneal structure made of both paravertebral sympathetic ganglions...

BACKGROUND: Although radiofrequency-assisted devices have sometimes been used in partial splenectomy, this is not a common technique. This report describes the first case of laparoscopic partial splenectomy using an RF-assisted device (Coolinside) which allows both coagulation and transection of the parenchyma and eventually the protective coagulation of the remnant side. CASE PRESENTATION: A 27-year-old woman was found to have a giant hydatic cyst measuring 12...

Raoultella planticola is an aerobic Gram-negative bacterium belonging to the Enterobacteriaceae family. Initially identified in the 1980s, its pathogenic potential was further recognized when the first case of bacteremia was reported. Since then, only a few infections caused by this pathogen have been described. Although considered an opportunistic agent, fatal outcomes are associated with the infection by this pathogen, since it is more prevalent among the patients with immunodeficiency. The authors report the case of a middle-aged man diagnosed with end-stage renal disease and alcoholic pancreatitis, who was admitted to the emergency department with septic shock...

BACKGROUND: Schwannomas are mesenchymal tumors arising from the neural sheaths of peripheral nerves. They can almost develop in any part of the body, while head, neck and extremities are the most common sites. Occurrence in the retroperitoneum is rare. Schwannomas can show secondary degenerative changes including cyst formation, hyalinization, hemorrhage, and calcification, whereas the ossified retroperitoneal schwannoma was only reported in a malignant one. CASE SUMMARY: We first present a benign ossified retroperitoneal schwannoma in a 61-year-old female...

Appendiceal mucocele is a cystic dilatation of the appendix due to abnormal appendiceal mucinous secretion. Cystadenoma of the appendix is one of the most common causes and is encountered in 0.6% of all appendectomy specimens. The diagnosis may be difficult due to the asymptomatic nature of the disease; pain in the right lower quadrant may be the only symptom. Complex ovarian cyst, urolithiasis or cystic hydatid disease of the liver have been reported as mimicking appendiceal mucocele in the literature. In this study, we present a case of mucinous cystadenoma of the appendix mimicking retroperitoneal hydatid cyst in a 59-year-old woman...

INTRODUCTION: Primary retroperitoneal mucinous cystic neoplasm (PRMCN) is a rare retroperitoneal tumor with female predilection. It is classified into 3 types: benign mucinous cystadenoma (MCA), borderline mucinous cystadenoma (MCAb), malignant mucinous cystadenocarcinoma (MCAc). This study retrospectively evaluates the prevalence of PRMCN among retroperitoneal neoplasms resected between June 2006 and January 2015 at a referral center. Authors' experience with PRMCN is reviewed, and a new case of PRMCN, incidentally diagnosed during pregnancy is reported...

BACKGROUND: Gastrointestinal (GI) tract duplication cysts or enteric duplication cysts are rare congenital malformations sometimes found on the mesenteric aspect of segments of the alimentary tract. Enteric duplication cysts are lined by normal GI epithelium and may be classified as foregut, mid-gut, and hindgut cysts. Except in very rare cases of retroperitoneal enteric duplication cysts, these cysts communicate with the GI tract and share a common blood supply. Concurrent congenital malformations are not uncommon and malignant transformation within enteric duplication cysts has also been reported...

We present the case of a 70-year-old man with a giant right-sided retroperitoneal pseudocyst, confirmed histologically after resection to be benign with appearances dissimilar to pancreatic and adrenal tissue. The cyst was noted incidentally on table at the time of laparoscopic surgery. Retroperitoneal pseudocysts most commonly arise from the pancreas and adrenal glands occurring as a result of an inflammatory process. Primary retroperitoneal pseudocysts are a rare entity. This case highlights the importance of examining the patient thoroughly and not focusing on the obvious...

Teratomas are neoplasms comprising of tissues derived from more than one germ layer. Most common sites are gonads, sacrococcygeal, mediastinal, retroperitoneal, and pineal region. Here, we report a case of 2 -year-old previously healthy female toddlerwho presented with fever and right upper quadrant abdominal pain. Magnetic resonance imaging (MRI) of the abdomen revealed a right suprarenal nonenhancing cystic mass. Focal calcification was seen in the inferomedial aspect of the cyst. Complete surgical resection of the right adrenal gland was done...

Beyond the familiar disk herniations with typical clinical features, intervertebral disk pathologic conditions can have a wide spectrum of imaging and clinical manifestations. The goal of this review is to illustrate and discuss unusual manifestations of intervertebral disk pathologic conditions that radiologists may encounter, including disk herniations in unusual locations, those with atypical imaging features, and those with uncommon pathophysiologic findings. Examples of atypical disk herniations presented include dorsal epidural, intradural, symptomatic thoracic (including giant calcified), extreme lateral (retroperitoneal), fluorine 18 fluorodeoxyglucose-avid, acute intravertebral (Schmorl node), and massive lumbar disk herniations...

Bronchogenic cyst is a benign lesion which is commonly seen in the posterior mediastinum. Diaphragmatic origin in retroperitoneum is an unusual location for a bronchogenic cyst. Cross-sectional imaging modalities describe the origin and content of the cyst evidently. Magnetic resonance (MR) images of a 42-year-old male patient who attended ER with back pain revealed a huge retroperitoneal complicated bronchogenic cyst arising from the diaphragm and surrounding the abdominal aorta anteriorly. Bronchogenic cysts in the retroperitoneum rarely originate from the diaphragm and should be kept in mind in the differential diagnoses of abdominal cystic lesions...

Mucinous cystadenomas and cystadenocarcinomas of the ovary are clinically and histopathologically well-established common tumors. However, primary retroperitoneal mucinous cystic tumors are extremely rare, and although their histopathogenesis is still uncertain, several theories have been proposed. Most authors suggest that they develop through mucinous metaplasia in a preexisting mesothelium-lined cyst. An accurate preoperative diagnosis of these tumors is difficult because no effective diagnostic measures have been established...

Obesity and metabolic syndrome are the common causes of reproductive and fertility disorders in women. In particular, polycystic ovary syndrome, which is clinically characterized by hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology, has been increasingly associated with metabolic disorders. However, given the broad interplay between metabolic and reproductive functions, this remains a field of intense research. In this study, we investigated the effect of monosodium l-glutamate (MSG)-induced obesity on reproductive biology of female rats...
