Authors experienced intra-root cavernous angioma which is very rare case among cavernous angiomas of cauda equina. Our intra-root cavernous angioma was confirmed by findings from operating field and microscopic examination. We report this case with review of the literature.

cute appendicitis is the most common condition requiring prompt abdominal surgery to minimize morbidity and mortality. Sonography and computed tomography (CT) have been widely used as the preferred imaging tools in patients with suspected acute appendicitis. 1 In previous studies of these diagnostic techniques, the sensitivities and specificities of sonography were 67% to 88% and 78% to 100%, respectively, whereas the sensitivities and specificities of CT were 76% to 96% and 75% to 95%. [2][3][4][5][6] Hye Soo Koo, MD, Hyun Cheol Kim, MD, Dal Mo Yang, MD, Sang Won Kim, MD, Seong Jin Park, MD, Jung Kyu Ryu, MD Received December 17, 2012, Objectives-The purpose of this study was to evaluate the additional value of supplementary computed tomography (CT) after sonography for diagnosing acute appendicitis.Methods-Among 140 consecutive patients with suspected acute appendicitis who underwent both initial sonography and supplementary CT within 12 hours, 88 patients whose appendices could not be visualized on sonography were excluded. The remaining 52 patients (mean age, 37.3 years; range, 15-98 years) were enrolled in this study. Two radiologists retrospectively reviewed the findings of 52 sonographic and CT examinations, and the appendix of each patient was classified as normal, equivocal appendicitis, nonperforated acute appendicitis, or perforated appendicitis. Causes of right lower quadrant pain other than appendicitis were also recorded. The additional value of supplementary CT was evaluated by performing head-to-head comparisons between CT and sonographic results.Results-No patients with a normal appendix on sonography showed appendicitis on CT. In addition, there were no patients with a sonographic diagnosis of appendicitis who had a normal appendix on CT. Ten patients (19.2%) were determined to have additional value gained from CT. Among these 10 patients, however, the additional information from CT affected treatment modality decisions in only 5.Conclusions-Initial sonography can be as effective as CT in patients with suspected acute appendicitis when the results are definite. Supplementary CT should only be performed when sonography is inconclusive.

Neuroendocrine tumors (NETs) are tumors that originate from neuroendocrine cells throughout the body. NETs are most commonly found in the appendix, followed by the rectum, ileum, lungs, and bronchi. NETs arising in soft tissues are rare. Here we describe the sonographic appearance of a NET in the axilla.

Not only pelvic CT but also abdominal CT is acceptable for detection of pelvic fractures, in spite of its thicker sections and different reconstruction algorithm. Therefore, if abdominal CT has already been performed, additional pelvic CT might no longer be necessary in order to exclude a pelvic fracture.
