Hydatid disease of the primary type may involve CNS and bone. Compression of the spinal cord and spinal nerve roots, caused by hydatid material from an affected vertebra is a rare condition which makes surgical decompression mandatory. We report the neuroradiological findings in a case of vertebral hydatidosis, confirmed by surgical appearance and hystological examination.
Radiological diagnosis of Sturge-Weber's disease is based on the recognition of the characteristic "tram-line" type of calcification at routine skull X ray examination. Computerized tomography allows an earlier diagnosis since it shows smaller calcifications. It also provides a better appreciation of the associated parenchimal anomalies, such as cerebral atrophy, and an exact evaluation of the extent of the pial angiomatosis following intravenous injection of contrast. In four children with Sturge-Weber's disease CT clearly revealed the full extent of calcifications and vascular anomaly; in one of the children the diagnosis was possible before the appearance of the calcifications.
In order to evaluate the possibility of early detection of minimal cerebral damages in the professional boxers, ten young pugilists were submitted to complete neurological examination, EEG recording and CT-scan. Neuroradiological data, electrical patterns and neurological aspects were examined in connection with sporting career of each boxer. Neurological examination was normal in all cases. EEG patterns were considered normal in 3 cases, borderline in 4 cases and pathological in 3 cases. CT-scan was considered normal in 4 cases, borderline in 4 and pathological (showing signs of cerebral atrophy) in 2 cases. A good correlation was found between CT-scan pictures, EEG patterns and sporting career of the boxers: the pugilistis who suffered knockouts had pathological and/or borderline CT-scan and EEGs, while the pugilists who did not experience knockouts during their career showed a normal CT-scan and EEG, independently of the years of activity and number of matches.
The technical principles, clinical application and organisational problems associated with computerised axial tomography are discussed. Numerous examples of pictures obtained on the brain and the whole body and in the normal subjects and various diseases are presented.

PURPOSE: To report the clinical and neuroradiologic findings of superficial siderosis of the CNS, due to chronic subarachnoid bleeding of unknown origin. MATERIALS AND METHODS: We observed seven cases. The main clinical manifestations were progressive deafness and ataxia. Four patients had had previous cranial or cervical trauma, with root avulsion in two, many years before onset of deafness and ataxia. Neuroradiologic studies included MR (0.5 T in four and 1.5 T in three) and angiography of the brain in all cases, CT in six cases, MR of the spine in six, and myelography in four. RESULTS: MR demonstrated a rim of marked hypointensity in T2-weighted images, consistent with hemosiderin deposits, on the surface of cerebellum, brain stem, inferior part of cerebral hemispheres, and spinal cord. CT showed cerebellar atrophy in five cases, and a rim of mild hyperdensity around the brain stem in two. Angiographic studies were negative. Myelography showed cervical nerve root avulsion in two cases and a cervicodorsal extradural cyst in one. Cerebrospinal fluid contained RBCs in all the six examined cases. CONCLUSION: Although CT may occasionally suggest the diagnosis of superficial siderosis, MR demonstrates this abnormality to better advantage.
