The influence of computed tomography on clinical decision making in the evaluation of a nonvisualizing kidney.

Nonvisualization of a kidney in an elderly man was investigated by computed tomography (CT). Simple low lying ureteral obstruction was excluded, multiple pathologic abnormalities were identified and causes for the nonvisualization are postulated. This case report demonstrates the important effect CT scanning produced on the clinical management of the patient in question.

Internal packing in the control of hemorrhage from large retroperitoneal veins.

BACKGROUND: Hemorrhage from large retroperitoneal veins is usually controlled by suturing the venous tear. Infrequently, the extent and location of the tear and amount of hemorrhage preclude successful suturing. METHODS: In seven patients with severe hemorrhage from large retroperitoneal veins encountered in association with resection of retroperitoneal sarcoma (6) or repair of a ruptured abdominal aortic aneurysm (1), packing of the area with sufficient amounts of Surgicel (Ethicon, Johnson & Johnson, Somerville, NJ) and pressure for one half hour was used. RESULTS: All seven patients did not show any bleeding postoperatively and no clinical sequelae developed, with the exception of one patient who developed an abscess requiring drainage. CONCLUSION: Internal packing with Surgicel appears to be reliable in controlling venous hemorrhage not manageable by the standard methods and may be preferable to roll gauze packing.

Supradiaphragmatic bronchogenic cyst extending into the retroperitoneum.

We experienced a case of bronchogenic cyst located on the left lower pleural space extending into the retroperitoneum in a 33-year-old man with left chest pain. Preoperative imaging studies and operative findings showed a broad-based cystic mass on the left lower posterior pleura and diaphragmatic pleura extending into the retroperitoneal region across the diaphragm. Histologic studies proved this mass to be a bronchogenic cyst.

Radiology-pathology conference. Acinar cell carcinoma of the pancreas.

Acinar cell carcinoma (ACC) is a rare tumor that constitutes 1% of pancreatic neoplasms. ACC is defined as a carcinoma exhibiting pancreatic enzyme production by neoplastic cells. Clinical presentation is usually related to either local spread or metastasis. In this Radiology-Pathology Conference, the clinical presentation and imaging findings of a patient with ACC of the pancreas, along with the differential diagnosis, are reviewed.

Ruptured retroperitoneal lymphatic malformation.

Retroperitoneal lymphatic malformations can cause significant displacement, pressure, or entrapment of adjacent organs raising suspicion of a malignant retroperitoneal tumor. They often mimic ascites but may rarely be a cause of ascites. Computed tomography (CT) imaging findings in an infant with a cystic retroperitoneal lymphatic malformation and massive chylous ascites are reported.

[Giant retroperitoneal liposarcoma. One case report].

INTRODUCTION: Retroperitoneal Liposarcoma is a rare and primary malignancy developed from mesenchymal tissue. It's generally unique and shows an only one histologic component. We report a case of multicentric and synchronous liposarcoma (intraperitoneal and retroperitoneal) and with different histologic types. EXEGESES: A 53-year old man presented with abdominal pain, increased abdominal girth and weight loss. Physical examination revealed two abdominal masses. Computed tomography scan showed a very large retroperitoneal mass displacing the left kidney, digestive loops and vessels. The patient underwent surgery. One enormous mass of the left renal lodge measuring 50 cm, a retroduodenal mass measuring 15 cm and a nodule of the coecum were removed. Histological examination of the mass of the left renal lodge revealed mixed type liposarcoma (dedifferentiated and myxoid). Histological examination of the retroduodenal mass and of the nodule of the coecum revealed well-differentiated liposarcoma. CONCLUSION: Pathological, therapeutic and prognostic aspects of abdominal liposarcoma will be reviewed in this article.

Case report: giant tuberculous cystic lymphangioma of posterior mediastinum, retroperitoneum and groin.

Cystic lymphangioma is a very rare condition of unknown aetiology. It is generally regarded as a developmental malformation in which obstruction or agenesis of lymphatic tissue results in lymphangiectasia secondary to lack of normal communication of the lymphatic system. Most lymphangiomas occur in the neck (75%) and axillary region (20%). Lymphangiomas may rarely occur in the retroperitoneum, mediastinum, mesentery, omentum, colon, pelvis, groin, spleen, bone and skin. We present a case of multicompartmental tuberculous lymphangioma extending continuously from the superior posterior mediastinum through the retroperitoneum to the right groin, which responded to needle aspiration and antituberculosis drug therapy.

The use of laparoscopy in retroperitoneal pathology.

Laparoscopy is usually not performed for retroperitoneal disease. However, if the retroperitoneal process is palpable or displaces viscera, laparoscopy may allow visualization and directed biopsy. In a personal series of 316 laparoscopies reviewed retrospectively, 19 (6%) were performed primarily for retroperitoneal pathology. All patients had CT scans documenting a retroperitoneal process. A confirmed histologic diagnosis was obtained on directed laparoscopic biopsy in 16 patients, including 9 non-Hodgkin's lymphomas. There was no mortality or morbidity in this series. Laparoscopy is a useful modality in selected patients with retroperitoneal diseases, and its use should be considered when a histologic diagnosis is necessary.

Retroperitoneal actinomycosis masquerading as inflammatory pseudotumor.

Inflammatory pseudotumors present clinically as mass lesions and microscopically show a spectrum of nonspecific inflammatory and regenerative changes. When the mesentery or retroperitoneum are involved, differentiation from inflammatory fibrosarcoma poses a diagnostic problem. The authors report on a 7-year-old boy who presented with fever, anemia, weight loss, and a retroperitoneal mass. Needle biopsy results of the mass showed features consistent with inflammatory pseudotumor. Examination of the resected mass showed actinomycosis.

Klinefelter's syndrome and extragenital seminoma.

An extragenital metastatic seminoma in a patient with Klinefelter's syndrome is described. The increased incidence of many types of malignancies in patients with this chromosomal abnormality and the increased susceptibility of XXY cells to transformation by oncogenic SV-40 virus are discussed. A relationship is suggested circumstantially by these observations.
