Case Reports
Ultrasonography, CT and MRI of retropharyngeal ganglioneuroma: a very rare neoplasm in adults.
Ganglioneuroma, a rare benign tumour, very occasionally presents in adult life. We report a case with the additional unusual feature of a retropharyngeal location.

We report a case of extensive craniocervical bone pneumatisation presenting after minor trauma. The patient had neurological signs and initial radiographs showed multiple lucencies in the skull base and the atlas vertebra. CT established the true nature of this rare condition.

The pterygopalatine fossa is an important space because it communicates with the middle cranial fossa, orbit, nasal cavity, oral cavity, pharynx, foramen lacerum, and the infratemporal fossa via eight foramina and canals. We studied the pterygopalatine fossa, foramen rotundum, inferior orbital fissure, sphenopalatine foramen, pterygoid canal, greater and lesser palatine foramen, palatinovaginal canal, and the pterygomaxillary fissure with high-resolution CT to characterise the anatomy and variants of these structures. These structures were evaluated using axial and coronal planes. ⋯ The distance between the pterygoid canal and the lower wall of the sphenoid sinus was 2.2 mm anteriorly and 2.8 mm posteriorly (P < 0.01). The pterygoid canal showed various relationships with the sphenoid and ethmoid sinuses. In addition, a previously unreported situation, where the foramen rotundum was surrounded by the spheroid sinus, was observed.

We report a case of retained packing gauze in the right maxillary sinus following a Caldwell-Luc operation. Plain films showed total opacification of the right maxillary sinus. CT showed a mixed mesh-like soft tissue density and air in the centre of the lesion and a thick soft tissue band at the periphery of the right maxillary and ethmoid sinuses and nasal cavity.

Supratentorial glioblastoma: neuroradiological findings and survival after surgery and radiotherapy.
Few studies have attempted to correlate neuroimaging with outcome in patients with glioblastoma. Our aim was to evaluate the relationship between neuroradiological findings and survival in these patients. ⋯ The mean survival was 14.2 +/- 5 months (range 6-22). The extent of radiological evidence of necrosis within the mass correlated significantly with survival time, whereas tumour size, perifocal oedema and contrast enhancement did not.
