Clinical radiosotope investigations in hydrosyringomyelia and myelodysplasia.

Radioisotope ventriculography was applied clinically in myelodysplastic hydromyelia in three groups of patients: two patients with normal ventricles, two with obstructive hydrocephalus, and 16 with myelodysplasia. In the myelodysplastic group, radioassay in one patient demonstrated flow of radioistope down the hydromyelic cavity. Twenty scintigraphic studies on 16 myelodysplastic patients showed hydromyelia was present in all patients with spontaneously compensated hydrocephalus but in none of those with functional ventricular shunts. This relation between the hydromyelia and disordered ventricular hydrodynamics supports the Gardner hypothesis of myelodysplasia. Radioisotope ventriculography appears a safe and useful method of diagnosing hydrosyringomyelia and evaluating treatment by means of ventricular decompression.

Relapsing juvenile chronic subdural hematoma in adult life.

Two cases of relapsing juvenile chronic subdural hematoma with late relapse in adult life are presented and the literature reviewed. Both patients contracted subdural hematoma early in life; its persistence resulted in characteristic skull deformitites. The patients led an asymptomatic life until a second head trauma caused rebleeding into the old hematoma sac with recurring symptoms and signs. The source of rebleeding is the outer subdural membrane. Radiographic features vary, depending on the location and size of the subdural hematoma. The significance of localized thickening of the cranium is stressed in refining the differential diagnosis.

Metastases to the medulla of the spinal cord: myelographic features.

Intramedullary metastases to the spinal cord of non-neurogenic origin are exceedingly rare, comprising fewer than 1.6% of all metastases affecting the spinal canal and its contents. Plain films are normal. Irregular fusiform widening of the spinal cord is the most common myelographic feature, although nodularity is also present. Complete blockage is very rare. The authors describe the radiological features in 4 cases of intramedullary metastases of non-neurogenic origin. The differential diagnosis is discussed, and some pathogenetic mechanisms are postulated. It is important to recognize intramedullary metastases in order to plan the proper management.

Cervical internal carotid artery injuries due to blunt trauma.

Blunt or nonpenetrating trauma to the head and neck occasionally results in damage to the cervical segment of the internal carotid artery. This may produce neurologic signs and symptoms that mimic acute craniocerebral injury. The mortality and morbidity associated with these injuries are alarmingly high. These injuries may be missed if one relies only on computed tomography. Angiography is still the definitive procedure to diagnose these lesions. The clinical and radiographic features as well as the pathogenesis and mechanism of injury are discussed for 21 cases of injury to the cervical internal carotid artery due to blunt trauma.
