✓ The authors report a patient with bilateral papillomas of the choroid plexus of the lateral ventricles with documentation of cerebrospinal fluid (CSF) hypersecretion causing hydrocephalus. Special attention is given to the large volume of CSF produced by these tumors (removal of one tumor reduced CSF outflow by one-half) and to the fact that CSF diversion was not required after both tumors were removed. Since tumor removal alone was sufficient to stop the progression of hydrocephalus, we feel that this case supports the concept that elevated CSF production by itself is sufficient to cause hydrocephalus in patients with papillomas of the choroid plexus.

The sites of synthesis of transthyretin in the brain were investigated using in situ hybridization with [35S]-labeled recombinant cDNA probes specific for transthyretin mRNA. Autoradiography of hybridized coronal sections of rat brain revealed specific cellular localization of transthyretin mRNA in choroid plexus epithelial cells of the lateral, third, and fourth ventricles. Transferrin mRNA was also investigated and, in contrast to transthyretin mRNA, was localized mainly in the lateral ventricles. Our results indicate that substantial synthesis of transthyretin and transferrin mRNA may occur in the choroid plexus.

Exact Etiology

ABSTRACTIntracranial xanthogranulomas are rare benign tumors and occur most commonly as choroid plexus xanthogranulomas, which rarely become symptomatic. Exact etiology is still a matter of debate. We present a case of xanthogranuloma of the choroid plexus of the third ventricle, causing obstructive hydrocephalus of the lateral ventricles.

✓ A case is reported of hydrocephalus due to overproduction of cerebrospinal fluid (CSF) caused by villous hypertrophy of the choroid plexus in the lateral ventricles. A 7-year-old girl with mental retardation developed gait disturbance; hydrocephalus and a Dandy-Walker cyst were detected on computerized tomography. She was initially treated with a ventriculoperitoneal shunt; however, shunting failed to control the hydrocephalus. The excessive outflow of CSF suggested choroid plexus abnormality, and magnetic resonance (MR) imaging revealed enlargement of the choroid plexus in both lateral ventricles. The patient was therefore diagnosed as having hydrocephalus induced by overproduction of CSF, which was controlled by resection of the choroid plexus. Histological examination showed the structure typical of normal choroid plexus. This is a rare case of villous hypertrophy of the choroid plexus in which MR imaging assisted in the diagnosis.
