The Diagnostic Value Of MSCT In Adrenal Ganglioneuroma

Objective Discusses the ganglioneuroma CT performance characteristics, Combined with its operation or biopsy results pathologic biopsy contrast analysis, To improve the accuracy of the diagnosis, Explore adrenal ganglion cells neuroma and other non-functional adrenal tumors of the differential diagnosis problem.Study Subjects and Methods Collect shanxi medical university Nol hospital in October2009-February2012during the pathology and a complete clinical data adrenal ganglion cells neuroma15cases(Surgical specimens in12cases, biopsy specimens in3). No functional adrenal adenoma20cases, Metastatic7cases, no functional pheochromocytomas8cases.totally50cases,52tumors. In22patients were male, female patients with30cases. Age8-75years old, the median age43years old. Use Light Speet VCT64layer spiral CT scanner and SOMATOMA PLUS4single spiral CT scanning, thick layer of0.625mm, pitch0.984; All cases were confirmed by operation or laparoscopic pathology, or dynamic follow-up to diagnose. Analysis the image performance, including tumor size, shape, edge, position, calcification, hemorrhage, sac change, the density evenness, etc. Measurement of the tumor essence average CT value, draw up the time a density (T-D) curve and classification. The SPSS13.0statistical software package for the above data chi-square test and analysis of variance, P<0.05with a statistical significance.Results generally, Adrenal ganglion cells neuroma for ovoid, borders, substantial density, Peach on its special pointed to signs. And with other non-functional adrenal tumors are statistically significant (P<0.001).Good hair at the right adrenal lesions, part of the lesions of calcification within. Adrenal ganglion cells neuroma and other non-functional adrenal tumors on the flat and enhance the CT scan and of value is all have statistically significant (P<0.05). Section cell tumor flat when density and higher than the adenoma, less than a pheochromocytoma and metastases, and enhance scan in stage3are all lower than other three groups of tumor. Adrenal ganglion cells neuroma and other non-functional tumor T-D curve exists in the distribution types statistical differences (P<0.05). Adrenal section cell tumor much performance is A curve, no other functional tumor performance for B, C, D type.Conclusion Most clinical adrenal ganglion cells neuroma for non-functional tumor, no special clinical manifestation. The performance has a certain characteristics of MSCT, its diagnosis and differential is of important value. The scale of the tumor and CT value and the degree of strengthening was to identify non-functional adrenal tumors of the important parameters, The strengthening of the tumor way, time-density curve, the shape, the boundary, peach levy and pointed to the diagnosis of calcification in can play a help,can give clinical surgery and follow-up adequate imaging basis.
