Benign focal amyotrophy is an uncommon variant of neuron disease characterized by the gradual development of atrophy usually involving one upper extremity with a subsequent nonprogressive course. Previous descriptive reports have included normal radiological studies. We present a case of benign focal amyotrophy with a metrizamide CT myelographic finding of segmental cord atrophy in a distribution consistent with the patient's clinical findings.

The practical usefulness of computed tomography with intrathecal metrizamide in imaging the brain stem is illustrated in six examples where the lesions were misdiagnosed on intravenously enhanced computed tomography, angiography, or air study. Focal and diffuse atrophic changes of the brain stem were demonstrated in symptomatic patients where none of the other radiographic or clinical investigations were conclusive. Metrizamide computed tomography is probably the most sensitive method for imaging lesions in and around the brain stem and cerebellopontine angle.

The non-ionic water-soluble contrast medium Amipaque (metrizamide) shows a lowered neurotoxicity, and therefore it may be used in the entire spinal canal. The better visibility of fine structures compared with oily and gaseous contrast media allows an excellent diagnostic approach to all spinal affections. Our technique of myelography is described and typical examples are given.

We have studied the diagnostic value of computed tomography with metrizamide CSF enhancement in 37 infants. According to the method of injection, we called CT cisternography, CT ventriculography and CT cystography. These methods were useful for the morphologic and dynamic evaluation of the CSF pathways. We used them especially for the evaluation of hydrocephalus, skull base tumor, infantile subdural hematoma and its allied diseases, or congenital cystic lesion such as Dandy-Walker syndrome. The side effects in children are much less than those in adults.

Magnification angiography of the testis with selective injection into the testicular artery has been performed in patients with different lesions in the scrotum, either real or suggested. Characteristic angiographic appearances were found in epididymitis, testicular torsion, tumor, hematoma and hydrocele.
