Abstract A family in which the mother and two of four daughters had a diagnosis of pseudotumor cerebri and one son developed communicating hydrocephalus is described. The other two daughters both have a long history of headaches but no signs of intracranial hypertension. The argument is advanced that there exists a defect of cerebrospinal fluid absorption common to pseudotumor cerebri and communicating hydrocephalus.

✓ The central canal of the spinal cord has been proposed as a significant compensatory alternative pathway of cerebrospinal fluid (CSF) flow in hydrocephalus. Ten dogs were made hydrocephalic by a relatively atraumatic experimental model that simulates the human circumstance of chronic communicating hydrocephalus. The central canal was studied by histopathology and compared with 10 normal control dogs. In both groups the central canal of the spinal cord was normal in size, configuration, and histological appearance. In this experimental model dilatation of the canal and increased movement of CSF does not appear to be a compensatory alternative pathway.

Cerebrospinal Fluid Secretion

Papilledema is the cardinal clinical sign of increased intracranial pressure. In this chapter, we begin by reviewing the symptoms and signs of increased intracranial pressure. We next review potential causes of increased intracranial pressure, which include intracranial masses, obstruction of the ventricular system, obstruction of cerebral venous outflow, decrease in cerebrospinal fluid absorption, increase in cerebrospinal fluid secretion, cerebral edema, medications, and idiopathic intracranial hypertension. We then review the approach to the diagnostic evaluation of increased intracranial pressure, including the recommended neuroimaging studies and cerebrospinal fluid evaluation. Lastly, we discuss the basic management approach for the patient with symptoms and signs of increased intracranial pressure.
