[Surgically treated Zenker diverticulum: a double-contrast radiologic study and videorecording].

Sixteen patients who had undergone the surgical resection of pharyngoesophageal diverticula were investigated with combined double-contrast radiology and video-recording. In 11 patients morphological or functional anomalies were identified. The authors report their results and stress the high incidence of postoperative stenoses (18%) and recurrences (43%). The combined use of double-contrast examination and video-recording is suggested to detect such functional disorders as those which were identified in 68% of the patients in this series of cases.

[MR vs CT: which is the diagnostic advantage in neuroradiology].

The comparative adequacy was studied of the two main neuroradiological imaging methods, MR imaging and CT, through the analysis of 1500 MR examinations with a preliminary CT study. The comparison was made by giving a score to the diagnostic contribution of MR imaging, especially as far as changes in the therapeutical approach were concerned. The results varied according to the various pathologies, to the different anatomical regions explored, and to the site of the masses. The overall score was higher in the spine and the spinal cord than in brain pathology. In brain neoplastic pathology, eg, the diagnostic capabilities of CT and MR imaging were similar in most cases, especially in supratentorial locations, while MR imaging was clearly superior in the spinal cord district. In infratentorial location, the better anatomical details make MR imaging the method of choice. In conclusion, CT confirms its accuracy in the detection of brain pathology, while MR imaging proves more sensitive in white matter diseases, and in particular locations, e.g. the posterior fossa. In the spine and spinal cord districts, the very high average score mainly confirms MR capability to demonstrate spinal canal normal and pathological content. Moreover, the important role of MR imaging is stressed in pediatric pathology, together with CT primary role in emergency cases.

[Congenital spinal intradural and extradural cysts].

Two intradural and two extradural spinal cysts are reported. The authors compare these cases with others reported in the literature. They agree about the dorsal retromedullary site but they disagree about the age and sex. Although the cysts have been opacified only in two cases, the myelographic diagnosis was easy in every case except one. The myelo-CT is'nt necessary for diagnosis but it offers a better visualization of the relation between the lesion and the spinal cord.

[Radiological investigation of prolactin-producing pituitary microadenomas (author's transl)].

The CT scans and thin section sellar tomograms of 12 patients with amenorrhea, galactorrhea and hyperprolactinemia syndrome were analyzed. Three patients showed a remodeled sella on plain X-ray of the skull and a protrusion of the suprasellar cistern below the diaphragmatic line on pneumoencephalography (empty sella). CT scan confirmed the low absorption values within the sella and showed an intrasellar area of increased density after contrast infusion. In 9 patients, thin section tomograms showed an abnormal sellar configuration. 5 of these patients had an eccentric, high density area adjacent to the sellar floor on postcontrast CT scans. The remaining 4 patients did not show postcontrast enhancement.

Computed tomography for diagnosis of empty sella associated with enhancing pituitary microadenoma.

Ten cases of primary empty sella with clinical findings of a secreting pituitary adenoma were studied using computed tomography (CT). Scans performed before contrast medium infusion confirmed the diagnosis of empty sella. After infusion, eight cases were found to have a nodular area of increased density within the sella turcica. In two patients, the enhancement probably corresponded to the pituitary stalk; the other six patients demonstrated CT evidence of pituitary microadenoma. These six patients had surgical confirmation of the existence of neoplasm. Tomodensitometric diagnosis of empty sella combined with microadenoma allows transsphenoidal microsurgery for complete tumor removal with preservation of the residual pituitary gland. For comparison, in a series of 21 patients suspected of having microadenomas, but without evidence of empty or enlarged sella, enhancing microadenomas were shown in 13 (62%).

[Myelography with B 15000, a new nonionic water-soluble contrast medium. Technical aspects and preliminary clinical experiences (author's transl)].

This is a report of myelography findings obtained in 50 patients with B 15000 (Iopamidol), a new non ionic water-soluble contrast medium. The procedure was easily carried out with a tilting table wired to a TV image amplifier. The dose of contrast medium injected intrathecally was 10 divided by 15 cm3 of a preconstituted solution containing iodine 200 or 300 mg/cm3. There were no accidents or major complications. The myelograms obtained with the test material afforded accurate diagnosis of intramedullary and extramedullary lesions, and signally of intervertebral disk protrusion and hernia.

[Radiological diagnosis of tumours of brain stem (author's transl)].

Cerebral pneumography, positive ventriculography and vertebral angiography were employed in the examination of 154 of tumour of brain stem at Departments of Neuroradiology in the city of Naples between 1962 and 1974. The findings in various sites are described and discussed and several examples are presented.
