Ultrasonic computed tomography (UCT) can aid in characterizing tissue for the detection and diagnosis of leukemic infiltration of the testes. Preliminary studies in 6 healthy adults and 26 patients (3-20 years old) with leukemia or non-Hodgkin lymphoma suggest that elevated speed of sound in the testis may be an indicator of leukemic infiltration. UCT may become an important screening method for detecting testicular involvement. In long-term follow-up, UCT can be performed more frequently and easily than biopsy, which is the current screening method...

Scrotal ultrasound examinations of 23 male adults and children with the diagnosis of lymphoproliferative disease (LPD) were performed. Diagnoses included acute lymphoblastic leukemia (ALL) (six patients); acute myelogenous leukemia (AML) (one patient); chronic lymphocytic leukemia (CLL) (nine patients); non-Hodgkin's lymphoma (four patients); Hodgkin's lymphoma (three patients). Sonography-biopsy correlation was 100% in identifying testicular infiltrates. Nine of ten patients with testicular involvement had bilateral disease...

Endoscopic ultrasonography (EUS) allows a visualization in vivo of the gastric wall. Five ultrasonic layers of different echogenicities are displayed; each corresponds to a precise anatomic structure. In gastric diseases this layering evidently changes. In 10 patients with suspected primary gastric lymphoma, EUS showed a characteristic thickening of the second, the second and third layers, or a diffuse, transmural thickening of the entire wall. A precise correlation between the longitudinal and depth infiltration observed at EUS and the surgical finding was seen in all patients...

Focal changes in the spleen were rare findings in a large clinical material (less than 1% of cases). In a prospective study, which included 580 patients, lesions in the spleen were found in 40. Four focal lesions were due to infiltrates from non-Hodgkin's lymphoma. Twenty-one lesions with low echoes consisted of twelve infiltrates from Hodgkin's disease (six patients) or non-Hodgkin's lymphoma (six patients), five were due to fresh splenic infarcts and one each to an abscess, a metastasis from a carcinoma of the stomach, sarcoid and a haemorrhage...

Four patients with hepatocellular carcinoma (HCC) out of a group of 132 with non-Hodgkin's lymphoma (NHL) are described. HCC was the most common second neoplasm in this series; in contrast, only 2 cases of HCC associated with NHL have been reported in the English literature. The diagnosis of HCC was suggested by ultrasound (US) and confirmed by ultrasonically guided fine-needle biopsy (UG-FNB). The 4 cases of HCC arose from cirrhosis. In this series, 10 out of 132 patients (7.6%) presented cirrhosis. Some considerations concerning the possible role of NHL (and/or the related therapy) in promoting the development of HCC in cirrhotic patients are discussed...

We report the diagnostic, prognostic and therapeutic features of non-Hodgkin's lymphoma in eight patients in whom the disease was seen as a primary tumor of the liver. This series illustrates the variety of situations in which lymphoma might be diagnosed: (a) abdominal pain and hepatomegaly (three cases), (b) incidental finding at evaluation of a patient with cirrhosis (two cases), (c) secondary neoplasm after treatment for Hodgkin's disease (one case) and (d) complication of AIDS (two cases). In most cases, clinical and/or radiological features were nonspecific...

Ultrasonically guided fine-needle biopsies were performed from 28 adrenal lesions in 28 patients. In 15 patients adrenal enlargement was an incidental finding. In 17 of 18 (94%) patients with metastatic spread combined cytological and histological examination disclosed secondary malignancy, and in 4 of 5 patients with primary neoplastic disease the combined microscopic examination concluded primary neoplasia. However, it was not possible to classify these lesions as being of a malignant or a benign nature. A false positive diagnosis of a hepatocellular carcinoma of the clear cell type was made in one case...

Ultrasonically (US) guided percutaneous tissue core biopsy of the spleen was done on 46 patients with malignant lymphomas. The biopsies were undertaken as a staging procedure in 32 patients, as a restaging procedure in 7, during follow-up in 2, and as a diagnostic step in 5 (previously undiagnosed cases with clinically and ultrasonographically suspected lymphoma). In 45 patients, the tissue core specimens obtained by US-guided biopsies were sufficient for a correct histologic examination; in one patient, the specimen was considered inadequate...

Based on own experience and on the published literature we report about indications and efficiency of endosonography (EUS) in gastric tumors. The following conclusions can be drawn at the present time. Submucous tumors can be clearly differentiated from extragastric compressions. Although the endosonographic aspect does not allow to formulate an etiologic diagnosis, EUS findings can give hints regarding the nature of the submucous tumor (e.g. leiomyoma, lipoma, cyst). In 75% of cases malignant submucous tumors can be visualized and a correct preoperative staging can be performed...

A series of 14 patients with nodal and extranodal non-Hodgkin's lymphoma of the oral and neck region was analyzed by ultrasonogram evaluation. Eight nodal lymphomas and six extranodal lymphomas commonly exhibited almost completely similar ultrasonographic findings, specifically, clear delineation of the boundary echo and a homogeneous, weak internal echo, the so-called pseudo-liquid-like images. The results derived from our study suggest that ultrasonic diagnosis is also helpful in evaluating patients with lymphoma during the initial diagnosis and initial treatment like other diagnostic imaging modalities...

Analyzes the results of ultrasonic examinations of 111 patients with various forms of non-Hodgkin's lymphomas. Reviews ultrasonic semeiotics of non-Hodgkin's lymphadenopathy of the abdominal cavity and retroperitoneal space and of extranodal variants of lymphoma course (with involvement of the spleen and stomach). Suggests the most safe method for precision diagnostic aspiration biopsy of the spleen monitored by ultrasound. The author considers ultrasonic examination to be a valuable method for the diagnosis of non-Hodgkin's lymphomas; it is economic, rapid, safe, permits a simultaneous assessment of the status of many organs and systems...
