[Diagnosis and surgical treatment of extra-adrenal pheochromocytoma].

From 1980 until 1991 10 patients were operated upon a paraganglioma: 5 patients with an encapsulated solitary tumor, two with infiltrating tumors and 3 with metastatic disease. The diagnosis of a catecholamine-producing tumor was most reliably made by norepinephrine analysis in urine and serum. The localization of the tumor was diagnosed in 9 of 10 cases by sonography and CT-scan. In 9 patients the tumor was excised completely, 4 times by extended resections. Whereas 4 out of 5 patients with an encapsulated solitary paraganglioma live to date without recurrence, all 3 patients suffering from metastatic disease had recurrent disease within one year postoperatively. A differentiated operative therapy of paragangliomas based on a clinical characterization is proposed: Encapsulated paragangliomas should always be excised. For solitary infiltrating tumors an extended resection may be necessary. This seems not to be justified for multiple infiltrating or metastasizing paragangliomas. Thus, only a reduction in size may be adequate for these tumors.

Abdominal aortic aneurysm and concomitant malignancy: what treatment?

UNLABELLED: The association of neoplasm and abdominal aortic aneurysm (AAA), although rare, may represents a therapeutic dilemma. MATERIALS AND METHODS: Between January 1990 and December 2004 in our departement 127 patients were submitted because of an AAA, in 8 cases there was an association with a neoplasm, in the greater part being a colon cancer. In 3 cases we performed a one stage surgery, in 1 case the chose was for a two stage surgery, for 3 patients we opted for an endovascular treatment by an endograft, in 1 case a pancreatic cancer was diagnosed 3 months after the prosthetic replacement of an AAA and there were no surgical indications because of the patient was in an advanced neoplastic stage. RESULTS: There weren't any prosthetic infection or more serious complications. The endovascular treatments were performed successfully without complications after few days being followed by cancer's resection. DISCUSSION: In case of this association the prognosis is related to neoplasm's stage. Timing depednds on the pathology that has the higher risk of short-term complication. Since Nineties author's reports in Literature about one stage surgery are more frequent, while now endovascular methods open new chances. CONCLUSIONS: One stage surgery is a safe option in case of association between AAA and cancer. We think that a good porpouse is the use of a vascular endograft in aneurysmal treatment followed, after few days, by cancer's resection.

Abdominal tuberculoma mimicking a pancreatic neoplasm: report of a case.

We report herein a case of clinically solitary abdominal tuberculoma. A 28-year-old woman was admitted to hospital for treatment of an abdominal tumor shown to be located in the head of the pancreas and compressing the superior mesenteric vein by echosonography and computed tomography (CT). There were no clinical signs or symptoms of tuberculosis in the lungs or abdomen. Thus, under the diagnosis of a neoplasm of the pancreas, an exploratory laparotomy was performed which revealed tuberculosis. The patient made an excellent recovery on anti-tuberculous treatment, and no evidence of a tumor was seen on a CT scan performed 6 months after the initiation of treatment. Abdominal tuberculoma is often mistaken for a malignant neoplasm and the nonsurgical diagnosis of this entity continues to be a challenge.

Intravenous contrast bolus in computed tomography investigation of mass lesion.

Using bolus intravenous contrast (25-75 Renografin 60) and 5-second scanning capability, better definition of vascular anatomy as well as the vascular nature of mass lesions in the chest and abdomen could be demonstrated. The immediate higher concentration of iodine in vessels and organs following initial bolus, improves visualization of these structures dramatically when compared to drip-infusion technique. A description of the technique and examples are shown.

Computed tomography of abdomen in staging and clinical management of lymphoma.

During July 1976 to Demember 1977, 150 patients with Hodgkin's disease and 138 with non-Hodgkin's lymphoma were examined by computed tomography (CT). In 45 cases 50 repeat examinations were conducted. Concurrent laparotomy and lymphography were performed on 68 and 56 patients respectively. The overall incidence of false-positive CT examinations as confirmed by laparotomy was 7.4%. In 18 patients with non-Hodgkin's lymphoma in the abdomen there was good correlation between the two techniques. Of the 50 patients with Hodgkin's disease who underwent laparotomy, 17 had splenic disease and 14 minimally enlarged lymph nodes in 20 areas; CT, however, detected only four diseased spleens and five minimally enlarged lymph nodes. Nevertheless, CT often detected enlarged lymph nodes missed by lymphography and was 23% more efficient than lymphography in detecting unsuspected disease. CT also detected unsuspected disease in patients with relapse of lymphoma. CT may replace other non-invasive investigations of abdominal disease in patients with lymphoma and give a reliable guide to prognosis. It does not, however, eliminate the need for laparotomy in staging Hodgkin's disease.

[Desmoid tumor of the mesentery secondary to colectomy. An exceptional cause of ureteric obstruction].

Desmoid tumours are rare lesions with a local invasive potential and a risk of recurrence, considered to be benign due to the absence of metastases. They are classified as fibromatoses and may be associated with Gardner's syndrome. The authors report an unusual case, in a 33-year-old woman, of a desmoid tumour invading the right ureter with upper tract dilatation. Etiologic factors (traumatic, hormonal, auto-immune...) are discussed, together with the treatment of choice to lower the risk of recurrence.
