Unicentric or Multicentric Castleman disease? A case report of a pelvic intraperitoneal mass in a middle aged woman.

Castleman Disease is a lymphoid disorder characterized by the presence of an enlarged or abnormal lymph node/lymphatic tissue. The disease is classified into unicentric or multicentric variants. The unicentric form is a benign disorder that is usually asymptomatic and consists of a single lymphoid mass that is predominantly located in the mediastinum, but can also rarely develop in the neck or abdomen.

Advanced native-kidney carcinoma in a heart- and kidney-transplanted patient: a case report.

Malignancies are one of the leading causes of death in long-term surviving transplant recipients. Dose and prolonged durations of immunosuppressive regimens are considered the main cause, through a direct oncogenic effect and a renowned interaction on physiological anti-viral and anti-oncogenic immune response. Specific neoplasms are known to occur with different frequencies according to the transplanted organ.

Peliosis hepatis associated with hereditary haemorrhagic telangiectasia.

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal, predominantly inherited disease characterized by diffuse telangiectases involving the skin, mucous membranes, lung, brain, gastrointestinal tract and liver. Peliosis hepatis is a rare, benign disorder causing sinusoidal dilatation and the presence of multiple blood-filled lacunar spaces within the liver. We report a case of an HHT patient with incidental magnetic resonance findings of focal hepatic peliosis.

Effectiveness of a single education and counseling intervention in reducing anxiety in women undergoing hysterosalpingography: a randomized controlled trial.

Hysterosalpingography (HSG) is generally considered a stressful and painful procedure; we aimed to evaluate whether a single education and counseling intervention could reduce women's distress and pain after undergoing HSG for infertility. Patients were randomized into control group (n = 108) and intervention group (n = 109). All patients filled the following questionnaires before and after HSG: Zung self-rating anxiety scale (Z-SAS), Zung self-rating depression scale (Z-SDS), and an ad hoc questionnaire designed to evaluate HSG procedure knowledge.

Intralesional hemorrhage in Krukenberg tumor: a case report and review of the literature.

Acute abdomen due to female genital apparatus disease is very rare. Most are due to intralesional effusion of benign tumors. The authors present a 40-year-old woman with acute abdomen pain due to haemorrhagic ovarian metastasis of colorectal cancer, focusing on the role of imaging to get the management of the patient.

Isolated nodular metastases in perirenal space: our experience of nine cases and review of the literature.

Aim: The aim of this paper was to report authors' experience and review of the literature on rare isolated perirenal space metastases from different primary tumors.

Methods: From January 2004 to August 2008 we evaluated retrospectively 9 patients with isolated nodular neoplastic lesions of the perirenal space with computed tomography (CT) imaging and we reported the follow-up after relapse of disease.

Results: All the masses resulted being of secondary tumor involvement (melanoma (2/9 cases 22.

CT and MR findings in extramedullary haematopoiesis with biliary system encasement: a case report.

Extramedullary haematopoiesis is the production of blood elements outside the bone marrow cavity. In our case computed tomography and magnetic resonance imaging revealed the presence of a rare localization of extramedullary haematopoiesis with encasement of the biliary system in a 59 years-old male Caucasian patient, with chronic myelofibrosis and hepatic failure's symptomatology. Computed tomography detected the presence of homogeneous hypodense tissue around intra-hepatic bile ducts with minimal contrast enhancement, strongly suggestive for extramedullary haematopoiesis.

Bilateral metachronous ovarian metastases from clear cell renal carcinoma: a case report.

Introduction: Bilateral ovarian metastases from a clear cell renal carcinoma are uncommon findings and need to be differentiated from primary cancers. Diagnostic imaging and histopathological features are often inconclusive, unless they are combined.

Case Presentation: A 56-year-old woman with a history of right radical nephrectomy for a renal clear cell carcinoma diagnosed 10 years earlier was referred for abdominal distension and pelvic pain.

Unusual abdominal findings of all-trans-retinoic acid syndrome: role of diagnostic imaging.

The standard therapy for patients affected by acute promyelocytic leukemia is based on all-trans-retinoic acid (ATRA), whose rare complication is a syndrome known as retinoic acid syndrome. We describe for the first time the computed tomography findings of a case of ATRA syndrome with typical pulmonary findings, along with the involvement of the upper abdomen organs (liver and spleen) as a further complication of the pathology.

Diagnostic imaging of lung cancer after heart transplantation.

Aims And Background: In heart transplant recipients pulmonary neoplasms are among the most frequent solid tumors; they have a rapid and aggressive course, and therefore require an early diagnosis. We describe the role that diagnostic imaging plays in different diagnostic moments of this disease.

Methods: We evaluated the incidence and diagnosis of lung cancer in patients who underwent heart transplants at our institution.

Diagnostic imaging of inverted Y duplication of the ureter with anomalous point angle. A case report.

A rare anomaly of ureteral duplication is the inverted Y configuration, occurring when 2 distal ureteral limbs fuse proximally to become a single tube draining the kidney. In international literature there is a female predominance. Previous reports documented distal limbs that were atresic or associated with ureterocele or ectopically located.

Henle loop basement membrane as initial site for Randall plaque formation.

Since the early description of Randall plaques in 1937, studies of the pathogenesis of stone formation mainly focused on the chemistry involving salt precipitation and crystallization, rather than tubular and interstitial medullar mechanisms of calcium concentration and supersaturation. In 2003, Bushinsky published a suggestive and inspiring sequence of events aimed to show that the basement membrane of the thin limb of the loop of Henle can be the first site of nucleation, as recently shown by the impressive work by Evan et al. The aim of this minireview is to verify the consistency of the Evan and Bushinsky theory with the current literature in the field.

Extramedullary hematopoiesis in chronic myelofibrosis encasing the pelvicaliceal system and perirenal spaces: CT findings.

We examined a 46-year-old male patient with idiopathic myelofibrosis diagnosed 28 months earlier. After chemotherapy and irradiation, CT showed nonnodular, soft tissue masses in the renal hilum, pelvicaliceal system, perirenal and periureteral spaces. Ultrasound-guided biopsy showed extramedullary hematopoiesis (EMH).

Unusual CT findings in urachus carcinoma with an extensive and atypical pattern of metastasis. A case report.

Carcinoma of the urachus is very rare. Usually it has a typical appearance on computed tomography, with calcifications in a midline supravesical mass, but advanced stages of this neoplasm require malignancy evaluation that is not easy to establish. We report a case of a urachal tumor where CT scan did not properly assess the response to chemotherapy, while it did show an uncommon metastatic localization in the laterocervical soft tissues.

Subserous uterine adenomyosis mimicking an adnexal mass on sonography.

Uterine adenomyosis usually manifests as diffuse disease involving the myometrium and the endometrial-myometrial junction, but it may also manifest as a focal lesion. It is usually only a few millimeters in diameter but may sometimes be larger. We report the case of a 32-year-old woman with a large isolated mass in the uterine wall.

Splenic metastases in gynaecologic cancer: clinical considerations, US, and CT diagnostic results.

Purpose: Splenic metastases from lesions in the genital system are an uncommon finding, both at staging and at follow-up. Most metastases are not an isolated finding but are quite frequently associated with metastases to lymph node or parenchymal sites. The aim of this paper is to describe the patterns of splenic metastasis at US and CT, the diagnostic imaging techniques most often employed in primary evaluation and follow-up of gynaecologic cancer.

Differential diagnosis of Krukenberg tumors using multivariate analysis.

Aims And Background: Krukenberg tumors are ovarian metastases from a gastroenteric malignancy in 90% of cases. At present, diagnostic imaging techniques (US, CT, MRI) do not provide any reliable diagnostic criteria to differentiate these metastases from ovarian primaries. We tried to use multivariate analysis to distinguish malignant ovarian primaries from Krukenberg tumors based on their differential natural history.

Epithelial ovarian cancer in female pseudohermaphroditism. A diagnosis by computed tomography and review of the literature.

We describe the case of a patient proven to be a female pseudohermaphrodite with a complete virilization syndrome who developed an epithelial tumor of the ovary of borderline malignancy. The tumor appeared as an abdominal mass with cystic features on ultrasonography. The diagnosis of the intersexual condition and adnexal cancer was made by computed tomography (CT).

Extraperitoneal pelvic leiomyosarcoma. MR findings in a case.

The magnetic resonance imaging (MRI) of a patient with nongynecologic pelvic leiomyosarcoma is presented. A retroperitoneal mass appeared under the broad ligaments, in the right paravesical and parametrial, lateral pararectal site. The mass leaned on the uterus and vagina.

Correlation between pretreatment prognostic factors and lymph node metastases in endometrial adenocarcinoma. Clinical application.

Purpose: To evaluate the prognosis of stage I endometrial adenocarcinoma, which differs by various prognostic factors. Some of them (tumor grading, histotype, myometrial infiltration, the latter evaluated with Magnetic Resonance Imaging) can be assessed before surgery. These prognostic factors correlate with patient survival and the presence of lymph node metastases.
