ABSTRACT

OBJECTIVE: The objective of our report is to describe color Doppler sonography findings of omental infarction and correlate them with surgical and pathology findings. Ten children underwent preoperative gray-scale and color Doppler sonographic examinations; omental infarction was confirmed at surgery. CONCLUSION: Color Doppler sonography findings were reviewed and correlated with surgical and pathology findings. Color Doppler sonography features of idiopathic omental infarction differ from those of infarction secondary to omental torsion.

ABSTRACT

OBJECTIVE: We know of only one previous study that has described the sonographic appearances of the inflamed Meckel's diverticulum in several cases (nine patients). Our study reviews sonographic, clinical, and pathologic findings in 10 patients with an inflamed Meckel's diverticulum. We also describe unique findings on color Doppler sonography for two of our patients. CONCLUSION: Sonographic findings of an inflamed Meckel's diverticulum may mimic findings for acute appendicitis or intestinal duplication. In patients with rectal bleeding due to diverticulitis, the visualization of a tubular hyperechoic structure on sonography is suggestive of Meckel's diverticulum. The inflamed Meckel's diverticulum may present as a cyst, but its mucosal layer is more irregular than that found in an intestinal duplication. We found that routine color Doppler sonography revealed anomalous vessels and signs of inflammation on the wall of the Meckel's diverticulum.

ABSTRACT

Estudaram-se 146 casos de plexos coróides provenientes de autópsias realizadas no Departamento de Patologia da FFFCMPA, no período de janeiro de 1983 a outubro de 1984, com a finalidade de analisar as alteraçöes histopatológicas nas diferentes fases da vida. As idades dos pacientes estudados oscilaram de 26 semanas de vida intra-uterina a 87 anos. O estudo abrange 6 fetos, 26 recém-nascidos, 34 casos até um ano de idade, 4 de um a dois anos, 14 de 2 a 10 anos, 3 de 10 a 20 anos, 7 entre 20 a 30 anos, 14 de 30 a 40 anos, 23 de 40 a 60 anos, 12 de 60 a 80 anos e, três acima de 80 anos. A análise dos casos demonstrou diferencas quanto ao aspecto histopatológico dos plexos coróides, que variaram de células epiteliais vacuolizadas, presença de material eosinofílico no interstício - nos primeiros anos de vida - a calcificaçöes restritas ao glomus e psamomas ou calcificaçöes grosseiras, cuja intensidade acentuou-se com o aumento da faixa etária

ABSTRACT

Descreve-se um caso de paciente masculino, de 45 anos de idade, que foi hospitalizado por crises convulsivas. O exame neurológico revelou exoftalmia com ptose palpebral e ausência de reflexo fotomotor no olho esquerdo. O exame de fundo de olho demonstrou a presença de edema de papila bilateral. A radiografia de crânio e a angiografia carotídea esquerda revelaram processo expansivo localizado junto à pequena asa do esfenóide. O paciente foi submetido à cirurgia com resseçäo do tumor, cujo diagnóstico histopatológico foi de cistos epidermóides múltiplos intracerebrais, com desenvolvimento de carcinoma epidermóide em um deles, com infiltraçäo de meninges
