RESUMO
After a difficult nasal intubation a premature infant leaked cerebrospinal fluid (CSF) from one nostril. After developing bacterial meningitis, the baby was referred for neurosurgical management of the CSF fistula. Transaxial computed tomograms demonstrated a nasal encephalocele, but coronal scans were needed to show the defect in the cribriform plate.

Carbon-11-labeled amino acids have been successfully used to image brain tumors by PET. This study was undertaken to evaluate the potential of L-3-[123I]-iodo-alpha-methyl tyrosine (123IMT) for metabolic imaging of brain tumors. Ten patients (glioblastoma, oligodendroglioma, lymphoma, and metastases) had early and delayed brain SPECT with a rotating gamma camera after i.v.-injection of 200-300 MBq 123IMT. In nine patients the tumors showed intense uptake of the radiotracer. Tumor-to-brain tissue ratios were between 1.4 and 2.6. 123IMT shows potentials for monitoring the effects of brain tumor therapy.

Radiologic diagnosis of intramedullary lipomas has been unreliable for a long time and many of these tumors have not been recognized. The introduction of computed tomography, and lately of magnetic resonance imaging, has led to great progress in the accurate identification of spinal cord tumors as well as in the recognition of type specificity of these lesions. An evaluation of the diagnostic value of magnetic resonance imaging and microsurgical technique for the optimal therapeutic outcome is discussed.

A 40-year-old female patient developed a nearly complete tetraparesis within two weeks. Neurological examination showed nearly complete tetraparesis, complete sensory impairment from the level of C4 and hyperreflexia of tendon jerks. Radiological examination showed a space occupying lesion with an extraspinal extension. Operative decompression was carried out and the patient recovered completely within 3 months.
