A 74 year old patient with diabetes mellitus was hospitalized because of nausea, recurrent vomiting and increasing fatigue. Shortly before admittance the patient had diarrhea. He also reported a recent onset of aversion against meat consumption. Clinical investigation revealed a possible right-sided paraumbilical abdominal tumor, normal bowel sounds, a vascular bruit and a normal white blood count with increased band forms. During hospitalisation the general condition of the patient deteriorated rapidly with fever and increasing numbers of immature granulocytes. The patient finally died under the symptoms of a paralytic ileus with hypotonia and hypoglycemia. Autopsy revealed a fist-sized stenosing tumor in the cecum with the histology of a mainly well differentiated, cylindrocellular adenocarcinoma. As immediate cause of death a bilateral paracentral lung embolism with pulmonary edema was found, the latter probably as immediate consequence of preterminal heart failure.

In this prospective study, we assessed the diagnostic capabilities of multidetector computed tomography (CT) in various esophageal pathologic conditions. Thirty-three patients underwent a multidetector CT study after esophageal distention by means of effervescent powder administered after induction of pharmacologic esophageal hypotonia. All acquired images were post-processed with two- and three-dimensional software tools. The CT data were compared with the results of conventional radiology (33), endoscopy (28), endoscopy ultrasonography (14), or surgery (14). Follow-up ranged between 4 and 15 months. Esophageal distention in the upper and middle thirds was classified as "good" in 32 of 33 cases (97%); in the lower third, esophageal distention was "good" in 21 of 33 cases (64%). Final diagnoses were leiomyoma (six cases), squamous cell carcinoma (six), adenocarcinoma (four), esophageal infiltration by thyroid cancer (two), benign polyposis (two), chronic esophagitis (five), post-sclerotherapy stenosis (one), no abnormalities (seven). When good distention was achieved, the thickness of unaffected esophageal wall was less than 3 mm (range, 1.5-2.4 mm; mean, 1.9 mm). Pathologic wall thickening was observed in 25 of 33 cases (76%), with values ranging between 3.6 and 36 mm (mean, 9.6 mm). Spiral CT demonstrated 21 true positive cases, and seven true negative cases. There were four false negative cases and one false positive case. Sensitivity was 84%, specificity was 87%, diagnostic accuracy was 85%, positive predictive value was 95%, and negative predictive value was 64%. Evaluation of the esophagus with multidetector CT is a promising technique and easy to use, allowing panoramic exploration, virtual endoluminal visualization, accurate longitudinal and axial evaluations, and simultaneous evaluation of T and N parameters.

Giant intradural metastases of nonneurogenic origin involving multiple segments represent an extremely rare manifestation of an unknown primary. The respective literature is very scarce. We present a 45-year-old female with complaints of low back pain for 4 years, involuntary urination for 2 years, and difficulty in using both lower limbs for 1 month. Examination revealed paraparesis with hypotonia. Imaging of lumbosacral spine revealed that expansile lytic destruction of vertebral bodies and posterior elements was noted from D8 to S2 vertebra and a large-sized patchy enhancing heterogeneous intradural extramedullary lesion was noted in D8-S2 level. Decompressive laminectomy from D11 to L4 vertebra and subtotal excision of the lesion were done. There was a marked improvement in the lower limb weakness and low back pain postoperatively. Histopathology revealed metastatic adenocarcinoma. Immunohistochemistry showed epithelial membrane antigen positivity. Accordingly, the aim of the surgery is strictly palliative. The majority of patients benefit with respect to neurological deficit/pain independent of the extent of resection. Thus, decompressive surgery is recommended to increase the quality of life. The occurrence of intradural spinal metastasis is rare. Only few cases of intra dural spinal metastasis involving multiple cord segments and osteolytic bony erosions have been documented. Hence this case is being presented here for its rarity and its uniqueness.
