    Notes: Abstract We report a case of Balò's concentric sclerosis. In the past, the diagnosis was usually made post mortem. In this case, we found that CT demonstrated only low-density lesions, but not their concentric pattern. However, MRI showed a striking feature, reminiscent of histopathology of Balò's concentric sclerosis, and played an important role in antemortem diagnosis of this rare demyelinating disease.

    Notes: Abstract We report the MRI and CT findings of an intracranial meningeal melanocytoma (IMM) arising from Meckel's cave and review the imaging characteristics of IMM. On CT, IMM constantly appear as well-circumscribed, isodense to slightly dense, extra-axial tumours with homogeneous contrast enhancement. This appearance is nonspecific and similar to that of meningiomas or small neuromas. On MRI, the signal of IMM is strongly related to the amount of melanin pigment: the more melanin, the more shortening of T1 and T2 relaxation times. Only when it shows as a homogeneous mass, bright on T1 and dark on T2 weighting, can a specific diagnosis of a melanin-containing tumour be made. However, this still cannot provide a distinction between IMM and malignant meningeal melanoma.

    Notes: Abstract We present the CT and MRI findings in a 75-year-old woman with a huge pathologically proven lingual thyroid which underwent goitrous degeneration. CT and MRI showed a midline, tongue-based, exophytic mass with areas of necrosis and heterogeneous contrast enhancement, as seen in large goitres in the normal thyroid gland.

    Notes: Abstract We report MRI and angiographic findings of an unusual giant arachnoid granulation in the left sigmoid sinus in a boy with headache. Its signal intensity was lower than that of cerebral cortex on T1-weighted images and higher on T2 weighting, mimicking dural sinus thrombosis.

    Notes: Abstract Cadaver studies were made to obtain more details about the arterial patterns in the thoracic and abdominal segments of the esophagus, with emphasis on the arterial supply to the lower esophageal sphincter (LES). The results showed that the inferior thoracic segment of the esophagus usually received blood supply from a single artery, with an average diameter of 1.42 ± 0.49 mm (X ± s), whereas the abdominal segment was commonly supplied by two arteries. The abdominal esophageal arteries coming from the left gastric artery were semi-circular in shape with an average diameter of 2.06 ± 0.70 mm. From these semi-circular esophageal arteries, 3 to 8 smaller arteries branched off and penetrated into the muscle of the abdominal segment of the esophagus or anastomosed with arterial branches from the inferior thoracic segment. Thus, the blood supply of the abdominal segment was richer than that of the inferior thoracic segment. This richness of blood supply, characterized by semicircular esophageal arteries in the abdominal segment, may be important for the function of the LES.

    Description / Table of Contents: Résumé Une étude autospique a été réalisée pour obtenir plus de détails sur le trajet de l'artère du segment thoracoabdominal de l'œsophage en insistant sur l'apport artériel du sphincter inférieur de l'œsophage (SIO). Les résultats montrent que le segment thoracique inférieur de l'œsophage reçoit habituellement son apport artériel d'une seule artère d'un diamètre moyen de 1.42±0.49 mm. Tandis que le segment abdominal de l'œsophage est le plus fréquemment vascularisé par deux artères. Les artères de l'œsophage abdominal naissant de l'artère gastrique gauche adoptent une forme semi-circulaire et présentent un diamètre moyen de 2.06±0.70 mm. De ces artères œsophagiennes semi-circulaires naissent trois à huit petites branches artérielles qui pénètrent dans le muscle du segment abominal de l'œsophage ou s'anastomosent avec les branches artérielles venant du segment thoracique inférieur de l'œsophage. Ainsi, la vascularisation du segment abdominal de l'œsophage est plus riche que celle du segment thoracique inférieur. La richesse de la vascularisation caractérisée par les artères œsophagiennes semi-circulaires au niveau du segment semi-abdominal peut être importante dans la fonction du SIO.
