    Notes: Abstract The main strategy in the treatment of nephroblastoma, as described in protocol SIOP 9/GPO, is preoperative chemotherapy for patients between 6 months and 16 years of age. Before treatment the diagnosis is made only by diagnostic imaging without biopsy. From July 1988 to February 1991, 130 children with the tentative diagnosis of nephroblastoma were treated preoperatively. The initial diagnostic images (excretory urography, ultrasound, CT, MRI) have been analysed both prospectively and retrosperatively and the findings correlated with the intraoperative and histological results. Of the preoperatively treated patients 93.8% had a Wilms' tumour or one of its variants. Five patients had a different malignant tumour and 3 patients, i.e. 2.3% of those preoperatively treated or 1.6% of all registered patients, had benign tumours of the kidney. Wilms' tumour generally presented as a well-defined mass with an inhomogeneous morphology on CT. On ultrasound only 24% of the tumours were homogeneous. Intratumoral haemorrhage and cystic areas occurred frequently; calcifications were rare (8%). With regard to caval involvement only ultrasound and MRI enabled the correct diagnosis, while CT could not differentiate compressions from invasion. The pretherapeutic diagnostic imaging was of sufficient accuracy to start preoperative chemotherapy without diagnostic biopsy.

    Description / Table of Contents: Summary The extended field of view imaging procedure named ”SieScape” provides, for the first time, a mode of establishing in real time a sonographic picture up to 60 cm in length. This allows the display of large organs or tumors as well as large areas of the body in a single view, without having to assemble several pictures. Furthermore, pathological find-ings can be shown in full size in their surroundings. This method makes it considerably easier to convey sonographic results to the therapist who is not present at the investigation and to control a finding, for instance a tumor, during therapy.
    Notes: Zusammenfassung Das Panoramabildverfahren „Siescape” erlaubt erstmals im Echtzeitverfahren die Erstellung eines sonographischen Schnitt-bildes von bis zu 60 cm Länge. Dadurch lassen sich große Organe oder Tumoren sowie ganze Körperareale auf einem Bild ohne Montage darstellen. Außerdem können pathologische Befunde in ihrer Umgebung großflächig dargestellt werden. Die Übermittlung des sonographischen Befundes an den nicht bei der Untersuchung anwesenden Therapeuten und die Kontrolle eines Befundes, z.B. eines Tumors, unter Therapie, werden dadurch erheblich verbessert.

    Description / Table of Contents: Summary The sonographic diagnosis of malignant lymphoma in childhood is described. Malignant lymphomas are sonographically relatively uniform: initial enlargement of the lymph nodes and organs involved and disturbance of normal echo texture by mainly hypoechoic lesions can be found. Generally, four sonographic patterns of infiltration are described: diffuse, small nodular, large nodular and bulky type. Secondary, tumor-related or inflammatory complications (e. g. dislocation or compression of vessels, thoracic inlet syndrome, venous thrombosis, ileus, urinary retention, abscess and effusion) can be sonographically evaluated. Response to therapy correlates with normalization of size and echo texture and recovery from tumor-related complications. Differential diagnosis with ultrasound is based on the topographic distribution and echo pattern of infiltration and, with certain restrictions, on the echogenicity of lesions and perfusion feasible with Doppler sonography. The primary diagnosis has to be established histologically.
    Notes: Zusammenfassung Die Ultraschalldiagnostik maligner Lymphome im Kindesalter wird beschrieben. Lymphatische Sytemerkrankungen des Kindes sind sonographisch relativ einheitlich: initial finden sich Lymphknoten- und Organvergrößerungen, sowie Störung der normalen Echotextur meist in Form von hypoechogenen Läsionen. An den parenchymatösen Organen werden sonographisch im wesentlichen 4 Infiltrationsmuster beobachtet: diffus, klein-nodulär, groß-nodulär und der „Bulcky-Typ“. Sekundäre, tumor- oder entzündungsbedingte Komplikationen (Gefäßkompression, Einflußstauung, Thrombose, Ileus, Harntransportstörung, Abszesse, Ergüsse) sind sonographisch erfaßbar. Ein Therapieerfolg ist im Ultraschall an der Normalisierung der Lymphknoten- und Organgröße, der Rückkehr der normalen Organechogenität und der Rückbildung tumor- bzw. entzündungsbedingter Komplikationen erkennbar. Differentialdiagnostische Hinweise ergeben sich aus dem topographischen Verteilungsmuster und dem sonographischen Erscheinungsbild der Läsionen, sowie unter gewissem Vorbehalt anhand der Echogenität und der dopplersonographisch analysierbaren Durchblutungsverhätnisse. Die primäre Diagnose ist immer histologisch zu sichern.
