Objective: To describe the CT
characterization of retroperitoneal Neurganglionic tumor in order to get a
better understanding of this disease.
Method: ⑴ 18 males and 8 femeals were
studied, all proved by operation and pathology, as well as bone biopsy 2
cases, Neuroblastomal (14 cases), Ganglioneuroblastoma (10 cases) and
Ganglioneuroma (2 cases), in each of them the mean age is 1 year 3 months,
3 year 6 months and 6 years respectively, Two cases of Ganglioneuromal are
complicated with leukemia and malignant pheochomocytoma. ⑵All cases were examined by CT
scanning and 14 of them had contrast enhancement preoperatively, 20 cases
were also examined by ultrasound.
Result: ⑴The tumor sizes were 2.0cm×2.5cm×2.5cm～16cm×10cm×8cm, 26 cases of the tumor were
all located in the retroperitoneal space, 22 cases were unilateral, 3 were
situated in mid-line prelumboscrally, 1 was bilateral.⑵The tumor were irregular in 20
cases and round shape in 6 cases; the tumor margin showed distinst 14 cases
and indistinct in 12 cases.⑶Twenty-five tumors showed mixture density and iso in tense
comparing with the kidney, 1 case with homogeneouse low density; 12 of 14
cases were enhanced inhomogeneously and 2 did not enhanced obviously; 23 of
26 cases showed different shapes of calcification.⑷ Retroperitoneal lymph nodes
were swelling in 19 cases. Liver metastases were found in 3 cases, vascular
encasement were found in 18 cases, tumor thrombus in inferior vena cava
were found in 1 case. The tumor extended into spinal canal in 3 cases.
Conclusion: CT scanning can prompt
the diagnosis of reperitoneal Neuroganglionic tumor and bolus injection of
contrast medium can further increase the understanding of the abnormality
within and around the tumor.
