Role of coronal oblique reconstruction as a complement to CT study of the temporal bone: normal anatomy.

PURPOSE: The purpose of this study was to demonstrate the usefulness of coronal oblique multiplanar reconstruction computed tomography (MPR CT) reformation parallel to the basal turn of the cochlea in the evaluation of the retrotympanum and hypotympanum to complete the standard CT examination of the temporal bone obtained with axial and coronal images. MATERIALS AND METHODS: We studied 30 patients aged 18-79 years for a total of 60 normal petrous pyramids. All examinations were performed on a multislice CT (MSCT) scanner (Sensation 16, Siemens, Erlangen, Germany) with axial volumetric acquisition and completed with reformations of coronal and coronal-oblique images. MSCT scan parameters for axial acquisition were set as follows: 0.75-mm scan collimation, FOV 300 mm, 170 mAs. Axial images were reconstructed at 0.7-mm thickness and with a reconstruction increment of 0.5 mm using a high-resolution bone algorithm. RESULTS: Coronal oblique MPR CT reformations provided additional information with respect to standard CT images in all cases. In particular, they enabled measurement of the craniocaudal and laterolateral diameters of the sinus tympani. In all cases, there was optimal visualisation of the ponticulus and subiculum. Analysis of the pyramidal eminence was improved thanks to its visualisation in profile. Moreover, we obtained an optimal representation of the hypotympanum, which was always exhaustively explored with only one reconstruction. Finally, in all cases, it was possible to identify the facial nerve canal and main vascular structures and to measure the distance between these and the sinus tympani, pyramidal eminence and hypotympanum. The coronal oblique CT reformation was of no advantage in the evaluation of the fossa of the oval window and the niche of the round window. CONCLUSIONS: Coronal oblique MPR CT reformation should not be considered an alternative to the standard CT examination, but it can represent a valid integration to provide additional information on particularly crucial districts characterised by frequent involvement of inflammatory and/or expansile disease and because of their difficult endoscopic approach. Moreover, it can represent a meaningful aid to optimise surgical planning thanks to its different perspectives of observation.

Large epidural hematoma associated with ipsilateral retrobulbar hematoma. Case report.

A case of large fronto-temporo-parietal epidural hematoma associated with ipsilateral retrobulbar hematoma is reported. A 24-year-old man soon after a head injury due to a traffic accident became comatose with anisocoria and hemiplegia and developed exophthalmos, conjuctival chemosis, downward and lateral displacement of the eyeball. CT scan of the brain and the orbit showed the large epidural clot communicating with an ipsilateral retrobulbar hematoma through a sphenoid bone fracture. The patient underwent emergency surgery. Postoperatively, he improved and was discharged in good conditions. On follow-up one month later he was symptoms free. The available literature is reviewed: our case seems to be the fifth reported.

[Significance of the circumferential involvement of the superior horn tip of the thyroid cartilage in pharyngo-laryngeal cancer].

UNLABELLED: The term "laryngopharyngeal carcinoma" indicates an advanced tumor involving both the supraglottic larynx and the pharynx in which the lesion origin may be difficult to assess. In 1981, Larsson et al. reported on the CT signs useful to distinguish the laryngeal/hypopharyngeal origin of advanced laryngopharyngeal carcinoma. We describe a new CT sign which may serve this purpose, namely the involvement of the thyroid cartilage superior horn tip. The thyroid cartilage superior horn, in fact, is involved early in the lesions originating in the pyriform sinus because of its close anatomic relationship with the posterolateral wall of the hypopharynx. MATERIALS AND METHODS. To assess the significance and specificity of this sign, we examined 15 patients with advanced laryngopharyngeal carcinoma with clinical, endoscopic and surgical evidence suggestive of tumors originating in the pyriform sinus. All CT examinations were performed with contiguous 4 mm slices before and after i.v. administration of iodinated contrast agents. Eighteen patients with surgically confirmed advanced supraglottic carcinoma were also examined. RESULTS: The thyroid cartilage superior horn tip was involved only in 3/18 supraglottic carcinoma patients; transcommissural infiltration of the larynx, involving both pyriform sinuses, was found in 2 of these cases and extensive invasion of the whole thyroid cartilage and of the cricoid ring in 1 case. CONCLUSIONS: The thyroid cartilage superior horn tip is a reliable sign of the pyriform sinus origin of advanced laryngopharyngeal cancer which is both sensitive (100%) and specific (83%). Moreover, this sign could play a major role because it represents, in most cases, the only and earliest sign of cartilage involvement. Finally, the encasement of the thyroid cartilage superior horn tip by abnormal tissue indicates tumor spread beyond the posterior pharyngeal wall. Therefore, these data can be very important for its early detection and useful for subsequent surgical planning.

[Computerized tomography in the evaluation of anatomic variations of the ostiomeatal complex].

This work was aimed at showing the main anatomical variations in the ostiomeatal complex which are usually depicted by CT. A hundred and thirty CT exams including 59 normal cases (45.4%) and 71 cases of chronic sinus disease (54.6%) were reviewed. The following anatomical variations were considered: concha bullosa, middle turbinate, septum, uncinate process and bulla changes, Haller cells and agger nasi cells. Anatomical variations were demonstrated in 69 patients--31 normal subjects and 38 patients with chronic sinusitis. The incidence of every anatomical variation was investigated and the results were compared with literature data. Excluding agger nasi cells, which were seen in nearly all patients, the most common variations were concha bullosa and septal spur and deviations, while the least common variations were those in the middle turbinate and uncinate process.

Gallbladder duplication: MR cholangiography demonstration.

Gallbladder duplication is a rare anatomic malformation. We present a case of gallbladder duplication in a patient who underwent laparoscopic cholecystectomy in which breath-hold magnetic resonance cholangiography showed the biliary anomaly, allowing a correct preoperative differentiation of the specific type of duplication.
