“…For this reason, excretory urography has historically been the most common technique used for evaluating this lesion. In the last decade, sonography and CT have also been used [2][3][4][5][6][7]. MR is becoming an increasingly acceptable imaging technique [8-1 4].…”

Ganglioneuroma is an uncommon neurogenic neoplasm that enters into the differential diagnosis of posterior mediastinal and retroperitoneal masses in children and adults. From 1978 to 1982, nine patients with this tumor were treated at the C. S. Mott Children's Hospital. Two children with retroperitoneal ganglioneuromas had ultrasonic examinations prior to surgery. The sonographic and anatomic similarity of the tumors in the two cases prompted this report. To our knowledge, the ultrasonic features of this entity have not previously been described. REPORT OF TWO CASESCase 1. A 7-year-old hoy was referred with a two-month history of intermittent left-sided epigastric pain. No constitutional or other symptoms were present. Physical examination revealed a tender mass in the left upper quadrant.Excretory urography showed an upward displacement of the left kidnev and a lateral deviation of the left ureter. Sonographic examination revealed a weU·defined and encapsulated mass separate from and ventral to the psoas muscle, and caudad to the lower pole of the left kidney ( fig. lA). It contained many fine low-level echoes. Although a few small sonolucent inhomogeneities and one area of increased echogenicity ( fig. 18) were present, the mass was largely homogeneous. No other retroperitoneal or hepatic abnormalities were identified. Computed tomography (Cf) ( fig. 1C) revealed no definite calcifications in this mass, which had attenuation coefficients ranging from 21 to 41 Hounsfield units. At operation, the mass was easily dissected from adjacent tissues. Examination of the gross specimen revealed a well-circumscribed, oval, reddish tan mass with a homogeneous cut surface. One small dystrophic calcification was identified microscopically. No evidence of neuroblastoma was present, and clinical follow-up shows no recurrence to date.Case 2. A 10-year-old asymptomatic girl was referred for evaluation of a 5-6-cm mobile, firm , nontender and smooth left midabdominal mass which had been detected by palpation during a routine physical examination. Excretory urography showed slight medial deviation of the distal left ureter, and the CT scan performed at another institution showed a left. sided retroperitoneal mass inferior to the lower pole of the kidney.Sonographic examination revealed a left lower quadmnt mass ( fig. 2) ventml to the left psoas and adjacent to, but separate from, the lower pole of the left kidney. The mass was smoothly marginated, approximately 6-7 em in diameter, and contained manv fine low-level echoes. The well. defined smooth discrete 'margins suggested encapsulation.At operation, the mass was adherent to multiple nerve trunks along the left paravertebral gutter. Pathologic evaluation revealed a homogeneous ganglioneuroma, witl10ut evidence of neuroblastoma. Clinical follow-up has been negative for recurrence to date.

“…A falsenegative MIBG scan may occur in a patient with liver involvement if 123 I MIBG is used (one instance) [9]. Although there is no characteristic sonographical appearance of metastatic disease in the liver, US seems to be superior to MIBG scintigraphy in this matter [27,35].…”

Abstract In a retrospective study we evaluated the agreement between the results of meta-iodo benzylguanidine (MIBG) scintigraphy and abdominal ultrasonography (US) in the diagnosis and follow up of neuroblastoma (NBL) with respect to the abdominal region. Data of 28 consecutive paediatric patients with NBL or suspected NBL were included (16 M/12 F, mean age 2.9 years, range 3 weeks ± 13.4 years). The results (as judged by the nuclear physician or radiologist, respectively) of 60 MIBG examinations ( 123 I and 131 I, including 26 single photon emission computed tomography (SPECT)) and US, respectively, performed within a period of 14 days, could be evaluated. Full agreement was reached in 37 comparisons (62%), while partial and no agreement was found in 17 (28%), and 6 (10%) comparisons, respectively. In 8 out of 37 comparisons with full agreement, 12 diagnosed lesions were histopathologically proven, while 11 comparisons with negative ®ndings were also negative in other clinical modalities. US diagnosed correctly in 68% of the histopathological proven lesions, while this was 54% for MIBG scintigraphy. In approximately 50% of the MIBG scans in which SPECT was available, SPECT provided signi®cant additional information.Conclusion Congruent results of MIBG scintigraphy and ultrasonography in the detection of abdominal lesions in patients with suspected neuroblastoma indicate a high reliability in the diagnosis and localisation. Due to the favourable results of additional SPECT, it is advisable to perform SPECT routinely in this diagnosis.Abbreviations NBL neuroblastoma á MIBG metaiodobenzylguanidine á SPECT single photon emission computed...
