Lymphangioleiomyomatosis (LAM) is a rare and slowly progressive disorder that usually arises in the lung, affects exclusively women in their childbearing years, and typically presents with progressive dyspnea on exertion and pneumothorax. Infrequently, extra-pulmonary LAM can occur in the retroperitoneum, uterine wall, mediastinum and intraperitoneal lymph nodes. Histologically, LAM is characterized by a proliferation of perivascular epithelioid cells (PEC) that express markers for both melanocytes and smooth muscle cells...

A 43-year-old otherwise healthy woman was found to have a retroperitoneal mass during a routine medical examination and was referred for further evaluation. Abdominal CT scan showed a well-delineated, low-density area that exhibited heterogeneous contrast enhancement. The area measured about 20 mm in size and was to the left of the aorta at the level of the inferior mesenteric artery. MRI showed a mass with heterogeneous hypointensity on T1 -weighted images and heterogeneous hyperintensity on T2 -weighted images...

Foetal magnetic resonance imaging (MRI) plays an increasingly important role in the diagnosis of foetal abnormalities. Over the years, we have successfully applied bi-parametric MRI (bp-MRI) to the following obstetric conditions: (1) neurologic vascular diseases; (2) assessment of lung parenchyma maturation; (3) renal pathologies, such as polycystic kidney, suspected renal infarction, unilateral or bilateral renal agenesis; (4) placental pathologies, as twin-twin transfusion syndrome or placenta accreta; (5) benignant and malignant congenital tumours or cysts of the liver, such as haemangioendothelioma, hepatoblastoma or metastatic neuroblastoma, of the kidney (e...

In this study the histologic grade of dedifferentiated liposarcomas was correlated with outcome in surgically resected specimens in 55 patients over a 19-year period at the University of Pittsburgh Medical Center. The tumors were located in the retroperitoneum (N=34); the extremities and thigh (N=16), and the remainder involved the spermatic cord and head and neck. Most tumors were large (mean=21 cm.) Follow up was available in all 55 patients (median=36months). Forty-one tumors classified as high-grade dedifferentiated liposarcoma (HG-DDLPS) had mitotically active pleomorphic and spindle cells and foci of necrosis...

The problem of retained surgical bodies (RSB) after surgery is an issue for surgeons, hospitals and the entire medical team. They have potentially harmful consequences for the patient as they can be life threatening and usually, a further operation is necessary. The incidence of RSB is between 0.3 to 1.0 per 1,000 abdominal operations, and they occur due to a lack of organisation and communication between surgical staff during the process. Typically, the RSB are surgical sponges and instruments located in the abdomen, retroperitoneum and pelvis...

Most gastrointestinal stromal tumors (GISTs) occur in the tubular gastrointestinal (GI) tract, but some present apparently outside the GI tract. In this study, we analyzed 112 GISTs located in the retroperitoneum. These tumors occurred in 55 women and 57 men with a median age of 65 years (range: 21 to 89 y). On the basis of clinically or histologically detected connections to GI tract, 15 tumors were considered likely of gastric, 9 duodenal, and 13 of small intestinal origin. The remaining cases were categorized by location as peripancreatic (n=25), pelvic (n=11), mesenteric (n=4), and of unspecified/miscellaneous sites (n=35)...

Soft-tissue sarcomas are a diverse group of rare mesenchymal malignancies that can arise at any location in the body and affect all age groups. These sarcomas are most common in the extremities, trunk wall, retroperitoneum, and head and neck. In the adult population, soft-tissue sarcomas arising in the abdomen and pelvis are often large masses at the time of diagnosis because they are usually clinically silent or cause vague or mild symptoms until they invade or compress vital organs. In contrast, soft-tissue sarcomas arising from the abdominal wall come to clinical attention earlier in the course of disease because they cause a palpable mass, abdominal wall deformity, or pain that is more clinically apparent...

Hybrid imaging using various radiopharmaceuticals is currently essential not only in detection and therapy response monitoring of tumors, but also in assessment of inflammatory or systemic diseases. Combination of positron emission tomography (PET) and magnetic resonance imaging (MRI) is still relatively new method with great prospects of comprehensive assessment using anatomical and multiple functional information. However, benefits of PET/MRI in thorax, abdomen and retroperitoneum are not completely defined...

Extrapleural solitary fibrous tumors are being increasingly reported. The retroperitoneum, deep soft tissues of the proximal extremities, abdominal cavity, trunk, head and neck are among the most common extraserosal locations reported. A recurrent solitary fibrous tumor involving the vagina of a 25-year-old woman is reported. Microscopically, the tumor was hypercellular and composed of mitotically active spindle cells. Immunohistochemically, the tumor cells were positive for vimentin, CD34, and bcl-2. Four cases of solitary fibrous tumors involving the vagina have been reported previously...

A 68-year-old man underwent an inguinal orchiectomy for a right testicular tumor and the pathological diagnosis was atypical lipomatous tumor. Nine years later, a resection procedure was performed for local recurrence. Five years after that second surgery, abdominal computed tomography (CT) findings revealed a low density mass 40 mm in size on the back side of the right kidney and enlarged fat in the retroperitoneal space. We performed a laparoscopic tumor resection under a diagnosis of lipoma or liposarcoma recurrence, and the pathological diagnosis was well differentiated liposarcoma...

BACKGROUND: Fetus in fetu (FIF) is a rare entity in which a malformed diamniotic monochorionic parasitic fetal twin develops inside a normal co-twin's body, most commonly in the abdominal cavity. FIF is differentiated from the teratoma by the presence of vertebral column often with an appropriate arrangement of other organs or limbs around it. CASE REPORT: A two-and-a-half-year-old girl presented with a painless abdominal swelling in the right hypochondrium. On imaging, a heterogenous soft tissue mass with internal calcific densities was noted in the retroperitoneum...

Erdheim-Chester disease (ECD) is a rare, non-Langerhans histiocytic disorder. The most common manifestations consist of polyostotic sclerotic lesions with the majority of cases also demonstrating soft tissue involvement of the sinuses, retroperitoneum, large vessels, heart, lungs, and central nervous system. Nuclear medicine can play an important role in assessing the extent of the disease with bone scintigraphy and fluorodeoxyglucose (FDG)-positron emission tomography (PET). We present the case of a middle-aged female who initially presented with tooth pain...

Though intrauterine contraceptive device (IUCD) is a safe and most frequently used long-term contraceptive method, it has some complications. Uterine perforation and intra-abdominal migration have been reported often, but a retroperitoneal migration is exceptional. Here, we are reporting an IUCD which perforated the uterus and migrated to the retroperitoneum; impinging into and obstructing left ureter causing severe hydroureteronephrosis due to the development of the left lower ureteric stricture.
