Many life-threatening conditions that can be diagnosed early in gestation may be treatable in utero using gene therapy. In order to determine in utero gene transfer efficiency and safety, studies were conducted with fetal rhesus monkeys as a model for the human. Included in these studies were Moloney murine leukemia virus (MLV)-based amphotropic retrovirus, vesicular stomatitis virus-G (VSV-G) pseudotyped MLV, and a VSV-G pseudotyped HIV-1-based vector, all expressing the enhanced green fluorescent protein (EGFP) as a reporter gene and driven by a cytomegalovirus-immediate early promoter (N = 16)...

Primary angiosarcoma of the spleen is a rare entity, but it is the most common primary splenic malignancy. These tumors demonstrate an aggressive growth pattern and can be single or multiple. The diagnosis should be suspected in a patient who presents with splenomegaly but without evidence of lymphoma, malaria, leukemia, or portal hypertension. The tumor may also present with acute abdominal symptoms secondary to spontaneous splenic rupture. We describe two cases of primary angiosarcoma of the spleen with computed tomographic, magnetic resonance, and sonographic features...

Histomorphometric findings at the study of marrow puncture specimens were compared to sonographic picture of the liver and spleen in 20 myeloid leukemia chronic. Histomorphometric and sonographic changes observed showed parallel pathological processes in the hemopoietic micro-surroundings and in the liver, spleen. Sonography proved able to considerably broaden diagnostic armory of the physician, to prognosticate leukemia outcomes, thus suggesting a differential approach to the disease treatment.

We report on a 52-year-old patient with acute myeloid leukemia. After induction chemotherapy, routine ultrasound displayed a round focal hyperechoic intrasplenic lesion. Tumor was primarily misdiagnosed for splenic hemangioma. Diagnosis of spontaneous progredient splenic rupture was made by color-coded Doppler sonography, sonographic follow-up examinations and confirmed by splenectomy for final treatment. No trauma was found.

High-dose chemotherapy, especially for bone marrow transplantation, causes a great degree of immunosuppression, and thus carries the risk for invasive fungal infections. Although hepatic and splenic involvement in disseminated candidiasis is frequent, involvement of these organs is rarely appreciated antemortem. During the last decade, focal hepatosplenic candidiasis has been recognized increasingly by ultrasound. We report the sonographic and clinical findings of 6 patients: 3 AML (acute myeloid leukemia), 2 NHL (non-Hodgkin's lymphoma), and 1 HD (Hodgkin's disease) who demonstrated multiple, small-nodule, hypoechoic lesions in spleen and/or liver after high-dose chemotherapy...

We report 3 cases of opportunistic infection of the liver and spleen due to Pneumocystis carinii, Candida albicans and Aspergillus with an unusual but similar sonographic appearance. In the patient with Pneumocystis we report for the first time this same appearance in the bowel and pleura. Histology showed either extensive fibrosis or focal fibrinous exudates as the underlying cause. Calcification, though present, was scanty and was not thought to be the likely explanation for the appearances.

The abdominal sonograms of 64 leukemic children were reviewed and correlated with clinical, hematological, and, when available, autopsy findings. Sonographic abnormalities including enlargement of the liver, spleen, pancreas, and kidneys, with or without alteration of parenchymal echo architecture, hydronephrosis, lymphadenopathy, and ascites were encountered in 70% of the patients. Ultrasound proved useful in detecting occult visceral leukemia and relapse, monitoring tumor response to chemotherapy, and assessing the complications of chemotherapy...

In three patients with acute leukemia candidal abscesses occurred. In spite of ready response to induction chemotherapy, septic fever as well as hepatic and splenic enlargement were observed. Broad-spectrum antibiotics did not improve the patients' condition either. Ultrasonography of liver and spleen revealed multiple, small echolucent foci and target lesions. Computed tomography detected multiple, hypodense foci 1-2 cm in diameter; after contrast medium application there was no enhancement. Candidal septicaemia was demonstrated in all three patients...

In order to determine the frequency of hepatosplenic abscesses in AML patients during chemotherapy and to evaluate the clinical and laboratory characteristics of this complication we performed a prospective study over a 28-month period. Fifty-five consecutive patients with de novo AML or relapse who received intensive chemotherapy underwent regular ultrasound examinations. In 16 patients (29.1%) hepatic and/or splenic abscesses were detected sonographically. Histopathological evidence for abscess formation was obtained in five of these 16 patients...
