Between July 1990 and September 1993, 32 patients with locally advanced irresectable adenocarcinoma of the pancreas, histologically proven by laparotomy, were involved in our study. Patients were treated with hyperfractionated, accelerated radiotherapy and simultaneous application of 5-fluorouracil and folinic acid. Chemotherapy was given on days 1,2 and 3.(More)
Although gray and white matter are distinguished by computed tomography (CT) in the cerebrum and cerebellum, their resolution in the mesencephalon has not been reported. CT and anatomic sections of the mesencephalon were compared to determine the relative densities of the superior cerebellar peduncles (white matter) and red nuclei and central gray matter.(More)
Using a CT/T 8800 scanner, axial and coronal images of the optic chiasm were obtained in a cadaver, 41 normal individuals, and six patients with symptoms of chiasmal glioma. The size and shape of each chiasm were determined. The normal chiasm appeared to be U- or boomerang-shaped in axial sections, and U- or dumbell-shaped in coronal sections. The average(More)
The computed tomographic (CT) images and records of seven patients with epidural lymphomas were reviewed to analyze their CT characteristics. Although no single specific pattern was identified, several signs were seen: (1) an intraspinal epidural irregular mass extending over several vertebral levels; (2) a mass with osteolysis or sclerosis; and (3) a(More)
Certain patients with cervical spondylotic myelopathy demonstrate instability in the upper cervical vertebral column associated with marked narrowing of the vertebral canal in the neighboring lower cervical segments. This combination of causative mechanisms creates difficulty in using routine surgical procedures, especially in elderly and severely(More)
The flocculus may simulate a cerebellopontine angle mass in computed tomography (CT). The CT appearance of the flocculus was compared with acoustic neuroma. Normal internal auditory canals, symmetric cerebellopontine angle cisterns, modest contrast enhancement, and a location posterior to the porus acousticus distinguish the flocculus from an acoustic(More)
