Late-onset papilledema following spinal injury. Case report.

Papilledema, is a known complication of various spinal pathologies. It has, however, been only infrequently reported following spinal injury, and may be overlooked in these cases. Presented herein is a 27 year old male who suffered thoracic and lumbar spinal injuries. Papilledema following mild increase in intracranial pressure (IICP) developed 3 weeks following trauma, and subsided within 8 weeks. The importance of routine repeat ophthalmoscopic examinations following spinal injury to detect changes characteristic of IICP is emphasized.

Lumbar spine dimensions in paraparetic patients: a 10 year follow up study.

Lumbar spinal AP radiographs of 13 C3-T11 paraparetic patients taken at about a 10 year interval were compared. The height (H) and maximum width (W) of the interapophysolaminar spaces (IALS), the width of the vertebral bodies at their waist (V) and the relationship between them showed minimal change over the follow up period. The difference between the late and early mean IALS height values increased caudally but was statistically significant only below L5. Subjective evaluation of the consecutive x-ray films revealed few new degenerative abnormalities. It is concluded that the normal aging process, which includes horizontal spreading of the lumbar vertebral bodies and narrowing of the lumbar spinal canal, is not accelerated by paraparesis and may even be retarded by relative immobilization.

CT and MRI in late-onset metachromatic leukodystrophy.

A 23-year-old patient suffering from mental deterioration was referred for CT study following her first epileptic fit. The study disclosed generalized atrophy and diffuse symmetric white matter hypodensities. Similar findings were found in her 13-year-old retarded sister. The diagnosis of metachromatic leukodystrophy (MLD) was confirmed by the finding of low arylsulfatase A (ASA) levels in cultured fibroblasts in both sisters. MRI study revealed widespread high intensity signals of T2 nature in the periventricular regions indicating changes in white matter composition.

Diagnosis of masses presenting within the ventricles on computed tomography.

The radiological and clinical features of 90 histologically verified intraventricular masses were reviewed. Computed tomography (CT) and plain X-rays were available in all and angiograms in over half the cases. The localisation, effects on the adjacent brain substance and the presence and degree of hydrocephalus was evident on CT. Two-thirds of colloid cysts presented as pathognomonic anterior third ventricular hyperdense masses and the other third were isodense; an alternative diagnosis should be considered for low density masses in this situation. Plexus papillomas and carcinomas mainly involved the trigone and body of a lateral ventricle of young children and caused asymmetrical hydrocephalus; the third ventricle was occasionally affected also in children and the fourth ventricle more frequently and usually in adults. Two-thirds were hyperdense, one-third of mixed or lower density. The meningiomas were dense trigonal tumours of adults generally arising in the choroid plexus, but two tentorial meningiomas passed through the choroidal fissure and caused a predominantly intraventricular mass. Gliomas frequently thickened the septum and generally involved the frontal segments of the lateral ventricles. They may be supplied by perforating as well as by the choroidal arteries, which supply most other vascularised masses within the ventricles. Only 10% of our cases did not fall into one of the former categories; these included low density non-enhancing dermoid or epidermoid tumours and higher density enhancing metastatic or angiomatous masses.

Cleidocranial dysplasia. A family study.

The incidental observation of Wormian bones in the skull and defective ossification of the public symphysis in a mildly scoliotic 12-year-old girl prompted a clinical and radiological study of members of her family. The diagnosis of cleidocranial dysplasia (CCD) was established by observing similar skeletal abnormalities in eight out of ten of them but the classical clavicular defect in only one, the last to be examined. Abnormal modelling of the medial end of both clavicles was observed in all those affected. A modelling defect of the public bones is suggested as an additional, hitherto undescribed, radiological sign. The progression with age of certain radiological features of CCD is discussed. It is suggested that this family represents an atypical variant of CCD. Such variance may be more prevalent in patients with mild scoliosis than presently suspected. A complete skeletal survey with espeical attention to the skull, pelvis and medial aspect of the clavicle and family studies may be essential for the definitive diagnosis of CCD in certain patients.

Metaphyseal multifocal osteosarcoma.

Two patients, aged six and eight years, having metaphyseal osteolytic and osteoblastic multifocal osteosarcoma are described. The condition is named "metaphyseal multifocal osteosarcoma". The metaphyseal areas are the sites of the pathological process. It can be postulated that a certain intensity of growth activity is the predominant factor in this condition and that this accounts for its multicentered presentation.

Computed tomography in ethmoid cell trauma.

Clinical and radiological evaluation of 19 patients with injury to the ethmoid bones following cranio-facial trauma is presented. The correlation of ethmoid trauma and damage to neighbouring structures is discussed. Two cases with damage to the orbits are demonstrated. These findings indicate that orbital involvement is relatively infrequent in association with ethmoid cell trauma. However, when it does occur, severe complications, such as infection and loss of vision may result. Early evaluation by computed tomography is the key to accurate diagnosis and prevention of these complications. Computed tomography is of inestimable value in the detection of minute and subtle bone fragmentation and sequelae.

Computerized tomography in conditions concomitantly involving the orbits and the paranasal sinuses.

Forty-three patients with computerized tomographic (CT) findings demonstrating concomitant orbital and paranasal sinus involvement are presented. Exophthalmos was the most common presenting symptom. Ethmoid and maxillary sinuses were most commonly affected. CT findings were of help in evaluating the extent of the various disease processes and are mandatory for treatment planning. Attention is drawn to the common association of paranasal lesion and ophthalmic manifestations. The combination of clinical presentation and radiological findings might indicate certain etiologies.

Spontaneous thrombosis of a traumatic cavernous sinus fistula.

Post-traumatic thrombosis of cavernous sinus and orbital veins has been reported in conjunction with carotid-cavernous sinus fistula (CCSF). CCSF are abnormal communications between the carotid artery and the cavernous sinus. Spontaneous thrombosis of a CCSF is a rare event mainly seen in the indirect (dural) type of fistula. We report on a patient with a possible post-traumatic CSSF which underwent partial spontaneous thrombosis and presented with an extreme degree of proptosis.
