RESUMO
We have reported two patients in whom absolute ethanol was used to sclerose arteriovenous malformations. Because of its low viscosity, liquid form, and devastating effect when injected intra-arterially, absolute ethanol is effective in treating AVMs, and it has been proven to have curative potential. For these same reasons it is also potentially harmful, particularly to nerves and possibly to skin.

We have reported a case in which focal uptake in a uterine fibroid simulated a sacral metastasis on bone scanning. CT suggested the correct diagnosis. However, a repeat bone scan using single photon emission computerized tomography (SPECT) was definitive in correctly localizing the abnormality. This method should be used when more precise localization is required than can routinely be obtained.

Misinterpretation of the diaphragmatic crura on axial computed tomography images is a recognized pitfall in diagnosis. The right diaphragmatic crus is generally longer and thicker than the left. The authors observed a case in which the left crus was thicker than the right, causing diagnostic difficulty. Obtaining scans at full expiration and full inspiration clarified the situation. Confirmation of respiratory variation in crural thickness was obtained in ten patients. The crura increased in thickness on inspiration, compared with the size on expiration.
