Objective To describe the CT characterization of retroperitoneal neuroganglionic tumor in order to get a better understanding of the disease. Methods Neuroganglionic tumors proved by operation and pathology (24 cases), as well as bone biopsy (2 cases), were studied in 18 males and 8 females. The mean age of neuroblastoma(14 cases), ganglioneuroblastoma(10 cases), and ganglioneuroma (2 cases) was 1 year 3 months, 3 years 6 months, and 6 years, respectively. Two cases of ganglioneuroma were complicated with leukemia and malignant pheochromocytoma. All cases were examined by CT scanning and 14 of them had contrast enhancement scanning preoperatively. 20 cases were also examined by ultrasound. Results The tumor sizes were 2.0 cm?2.5 cm?2.5 cm~16 cm?10 cm?8 cm. The tumors were all located in the retroperitoneal space, 22 cases were unilateral, 3 were situated in mid line prelumboscrally, and 1 was bilaterally located. The tumor were irregular in 20 cases and round shape in 6 cases; the tumor margin showed distinct in 14 cases and indistinct in 12 cases. Twenty five tumors showed mixture density and isointensity comparing with the kidney, 1 case with homogeneouse low density; 12 of 14 cases were enhanced inhomogeneously and 2 did not enhance; 23 of 26 cases showed different shapes of calcification. Retroperitoneal lymph nodes were swelling in 19 cases. Liver metastases were found in 3 cases, vascular encasement in 18 cases, tumor thrombus in inferior vena cava in 1 case,and tumor extending into spinal canal in 3 cases. Conclusion CT scanning can prompt the diagnosis of retroperitoneal neuroganglionic tumor and bolus injection of contrast medium can further increase the understanding of the abnormality within and around the tumor.

The effect of the autonomic nerves on the transmural dispersion of ventricular repolarization (TDR) under acute myocardial ischemia in intact canine was investigated. Using the monophasic action potential (MAP) recording technique, MAPs of the epicardium (Epi), mid-myocardium (Mid) and endocardium (Endo) were recorded simultaneously by specially designed plunge-needle electrodes at the left ventricular free wall under acute myocardial ischemia in 12 open-chest dogs. MAPD90 and TDR among three myocardial layers as well as the incidence of the early afterdepolarization (EAD) before autonomic nervous stimulation and during autonomic nervous stimulation were compared. It was found that 10 min after acute myocardial ischemia, TDR was increased from 55 +/- 8 ms to 86 +/- 15 ms during sympathetic stimulation (P < 0.01). The TDR (53 +/- 9 ms) during parasympathetic stimulation was not significantly different from that of the control (55 +/- 8 ms) (P > 0.05). The EAD was elicited in the Mid of 2 dogs (16%) 10 min after acute myocardial ischemia, but the EAD were elicited in the Mid of 7 dogs (58%) during sympathetic stimulation (P < 0.01). It was concluded that: (1) Sympathetic stimulation can increase the transmural dispersion of repolarization and induce early afterdepolarizations in the Mid under acute myocardial ischemia, which provide the opportunity for the ventricular arrhythmia developing; (2) Parasympathetic stimulation has no significant effect on the transmural dispersion of repolarization under myocardial ischemia.

The effect of the autonomic nerves on the transmural dispersion of ventricular repolarization in intact canine was investigated. By using the monophasic action potential (MAP) recording technique, monophasic action potentials (MAPs) of the epicardium (Epi), midmyocardium (Mid) and endocardium (Endo) were recorded simultaneously by specially designed plunge-needle electrodes at the left ventricular free wall in 12 open-chest dogs. MAPD90 and transmural dispersion of repolarization among three myocardial layers as well as the incidence of the EAD before autonomic nervous stimulation and during autonomic nervous stimulation were compared. The results showed that the MAPD90 of Epi, Mid and Endo before autonomic nervous stimulation were 278 +/- 11 ms, 316 +/- 16 ms and 270 +/- 12 ms respectively, the MAPD90 of Mid was significantly longer than that of Epi or Endo (P<0.01). MAPD90 of Epi, Mid and Endo were shortened by 19 +/- 4 ms, 45 +/- 6 ms, 18 +/- 3 ms respectively during sympathetic stimulation. Compared with that of the control, the transmural dispersion of repolarization during sympathetic stimulation was shortened from 44 +/- 4 ms to 15 +/- 3 ms (P<0.01), but early afterdepolarizations were elicited in the Mid of 5 dogs (41%) during sympathetic stimulation. Parasympathetic stimulation did not significantly affect the MAPD90 in the three layers. It is concluded that there is the transmural dispersion of ventricular repolarization in intact canine. Sympathetic stimulation can reduce transmural dispersion of repolarization, but it can produce early afterdepolarizations in the Mid. Parasympathetic stimulation does not significantly affect the transmural dispersion of ventricular repolarization.
