Plexus Papilloma

✓ An unusual case of a sacral, extradural choroid plexus papilloma involving the S1–3 level is described. This 50-year-old woman presented with a 4-month history of pain involving her right buttock, perineum, and leg. Contrast-enhanced magnetic resonance (MR) imaging of the spine revealed a well-defined, mildly enhancing sacral canal mass at the S1–3 level; its appearance was consistent with that of a benign tumor. Intraoperatively, the lesion was found to be extradural in location and was entwined among nerve roots in the sacral canal. Microscopic examination of the gross totally resected tumor revealed typical features of a choroid plexus papilloma. Despite performing a thorough neuroimaging workup (craniospinal contrast-enhanced MR imaging) for an intracranial or spinal primary mass, none was found. The choroid plexus appeared entirely normal; however, both a cavum septum pellucidum and a cavum vergae were noted. Extraneural choroid plexus papilloma, specifically intrasacral, extradural choroid plexus papilloma has not been previously reported. The present example is thought to have arisen either from ectopic choroid plexus tissue or perhaps by metaplasia from ependymal rests.

✓ 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.

Plexus Papilloma

The authors describe a unique case of a choroid plexus papilloma of the sacral nerve roots. This 60-year-old woman was admitted to the hospital because of a 1-year history of sacral pain, rectal and urinary bladder retention, and paradoxical episodic incontinence. Physical examination revealed sensory abnormalities in the S-2 dermatomes and poor rectal and bladder sphincter contractions. Contrast-enhanced spinal MR imaging showed a well-circumscribed, ovoid, homogeneously enhancing mass at the S1–2 level suggesting a diagnosis of ependymoma or schwannoma, and surgery allowed the identification and complete removal of a soft gray mass intimately adhering to the sacral nerve roots. Histological examination revealed a tumor consisting of papillary structures lined by a single layer of columnar cells, with an immunophenotype that satisfied the diagnostic criteria of choroid plexus papilloma. After diagnosis, contrast-enhanced brain MR imaging excluded the presence of a primary choroid plexus papilloma in the cerebral ventricles, thus ruling out a drop metastasis along the CSF pathways. A review of the literature did not reveal any similar cases of choroid plexus papilloma, and so the authors also discuss the inclusion of primary or metastatic papillary tumors in this unusual location as part of the differential diagnosis.

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 papilloma (CPP) is extremely rare in the brainstem. The authors report the case of a 10-year-old boy with a lesion in the pons that was misdiagnosed as a glioma preoperatively. The boy underwent partial resection of the lesion, which was diagnosed as a CPP based on histopathological findings. The authors review the MRI findings in this case and conclude that the presence of a well-defined boundary and no obvious cerebral edema are valuable features for distinguishing brainstem CPP from glioma. Although previous reports of parenchymal CPPs have described enhancement on contrast-enhanced T1-weighted MR images, the lesion in this case did not demonstrate significant enhancement. The authors note that the diagnosis of extraventricular CPP cannot be ruled out in a case of brainstem tumor without marked enhancement.

Plexus Papilloma

A choroid plexus papilloma is a rare CNS neoplasm arising from the neuroepithelial lining of the choroid plexus. A third ventricular location of a choroid plexus papilloma is rare compared with the more common sites in the lateral and fourth ventricles. Cystic choroid plexus papilloma represents an infrequent subtype that may present diagnostic ambiguity. The authors present a case of cystic choroid plexus papilloma within a cavum septum pellucidum that radiographically mimicked neurocysticercosis.

✓ The authors report an unusual case of a 2-year-old boy with a 3-month history of episodic rightward anterolateral head tilt and large-amplitude positional anteroposterior head bobbing reminiscent of bobble—head doll syndrome. This child experienced a sudden onset of drop attacks and then, within several hours, deep coma. The causative lesion was a contrast-enhancing, partially cystic third ventricular mass, which ultimately obstructed the aqueduct, producing profound obstructive hydrocephalus. An emergency ventriculostomy and endoscopic fenestration of the septum pellucidum was performed. Four days later, the tumor was completely resected by a transcallosal—transforaminal approach. The lesion was freely mobile within the third ventricle and contained a large cyst within its posterior pole; following drainage of the cyst, the lesion was easily delivered through the foramen of Monro. The histopathological diagnosis was choroid plexus papilloma. The child's neurological deficits, head tilt, and head bobbing resolved immediately after operation. To the best of the authors' knowledge, this represents the first well-documented report of bobble—head doll syndrome and drop attacks secondary to a choroid plexus papilloma. The highly mobile nature of the cystic lesion presumably led to its intermittent impaction within the foramen of Monro and/or proximal aqueduct; this produced the intermittent head tilt and bobble-head symptoms and, ultimately, resulted in acute obstruction of the aqueduct, causing the child's precipitous neurological decline.

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.
