Plexus Papilloma

✓ The authors report an intrinsic brainstem lesion that was diagnosed initially as a pontine cavernoma, which finally proved to be a choroid plexus papilloma. Choroid plexus papillomas are rare tumors of the central nervous system and are usually intraventricular in location. The occurrence of this tumor in an intraparenchymal location is extremely rare, and its occurrence within the brainstem is previously unreported. The authors also report a trial of chemotherapy with lomustine in the management of the residual tumor.

Plexus Papilloma

✓ Choroid plexus papillomas can metastasize to the subarachnoid space, but extensive metastasis has only been reported when the tumors are malignant. The authors report a case of diffuse, extensive metastasis to the craniospinal leptomeninges from a benign fourth ventricular choroid plexus papilloma in an adult. This 19-year-old woman presented with a 2-year history of headache, blurred vision, diplopia, and ataxia. Magnetic resonance imaging of the brain and spinal cord revealed obstructive hydrocephalus caused by a 4-cm, partially calcified, inhomogeneously enhancing tumor of the fourth ventricle that was displacing the pons, medulla oblongata, and cerebellum. Innumerable cystic lesions of varying size were also seen in the cranial and spinal leptomeninges. Histological examination of the resected fourth ventricular tumor and of a few of the leptomeningeal lesions revealed a benign choroid plexus papilloma and leptomeningeal choroid plexus cysts. This singular case of diffuse and extensive metastasis to the craniospinal leptomeninges from a histologically benign fourth ventricular papilloma adds to the available information about the biological potential of these tumors and expands the differential diagnosis of posterior fossa lesions with subarachnoid metastasis.

Plexus Papilloma

✓ The authors report a case of cystic choroid plexus papilloma that originated in the posterior fossa. No connection with the ventricular system was found intraoperatively. Magnetic resonance (MR) and computerized tomography imaging did not furnish a diagnosis, but findings of pathological examinations were consistent with those of choroid plexus papilloma. The authors describe the different appearances of the tumor on MR images and discuss the differential diagnosis with other tumors of the posterior fossa.

✓ This 9-year-old boy with a history of behavioral problems and worsening psychosis responded initially to treatment with haloperidol. However, a magnetic resonance image obtained as part of his psychiatric evaluation revealed an anterior third ventricle tumor and mild-to-moderate hydrocephalus. The resected tumor was found on pathological examination to be a choroid plexus papilloma. The patient had an uneventful postoperative course and remained free of psychosis or mood disorder at 1-year follow-up examination.

✓ Except for villous hypertrophy of the choroid plexus that may not be true tumors, multiple choroid plexus papillomas are extremely rare. The authors report a case involving multiple choroid plexus papillomas that were distinct from villous hypertrophy. These lesions were localized, one in the atrium of the right lateral ventricle and the other in the inferior horn of the left lateral ventricle. A review of the literature revealed that this case represented the first reported case of true multiple choroid plexus papillomas documented by findings on magnetic resonance imaging.

✓ Carcinoma of the choroid plexus is an extremely rare disease with a particularly virulent course. A case is reported in the left lateral ventricle of a young woman who is well 1 year after total excision of the tumor. The four previously reported patients with this disease who did well (two males and two females) were all children. Three of the four were treated with surgery followed by radiotherapy, and one with surgery alone. Although it appears possible that gross total removal may be curative, radiation therapy is suggested because of the distinct possibility that even the least aggressive-appearing lesions may degenerate and become rapidly fatal. Chemotherapy, although not used in any of the cases reported, is suggested as a possible adjunct in the treatment of this disease.
