Intraspinal metastasis of choroid plexus papillary carcinoma: a case
report and literature review
Abstract
Choroid plexus papillary carcinoma (CPC) is a rare intracranial
malignant tumor that originates from choroid plexus epithelium and is
categorized as a malignant type of choroid plexus papillary tumor. It
accounts for only about 0.05%-0.1% of all intracranial tumors [1].
CPC predominantly affects children, and a few cases are detected before
or shortly after birth. The lateral ventricle and the third ventricle
are the most common sites of choroid plexus tumors in children. CPC has
a higher propensity to occur in the fourth ventricle in adults. Tumors
are a rare occurrence in the cerebellopontine angle. Choroid plexus
papillary tumors have the potential to disseminate via the cerebrospinal
fluid. Currently, there is no literature reporting intraspinal choroid
plexus papillary carcinoma. We present a case of a 6-year-old male who
presented with headaches and was admitted to the Department of
Neurosurgery in our hospital. The MRI of the head revealed a cerebellar
mass, which was later confirmed as choroid plexus papillary carcinoma
through postoperative pathology. Six months after discharge, the patient
was admitted to the hospital again due to low back pain. MRI examination
showed an intraspinal mass, which was confirmed as choroid plexus
papillary carcinoma by postoperative pathology.
