Summary
Choroid plexus papillomas (CPPs) can present with unusual imaging features, sometimes mimicking other brain tumors. These atypical CPPs often correlate with combined papillary and solid or tubular growth patterns on pathology.
Area of Science:
- Neurosurgery
- Neuroradiology
- Neuropathology
Background:
- Choroid plexus papillomas (CPPs) are typically benign tumors with characteristic imaging and pathological findings.
- However, atypical presentations can occur, posing diagnostic challenges.
Purpose of the Study:
- To analyze the radiologic findings and corresponding pathologic growth patterns of choroid plexus papillomas (CPPs).
- To investigate unusual presentations of CPPs and their diagnostic implications.
Main Methods:
- Retrospective analysis of radiologic findings (location, size, enhancement, calcifications, hydrocephalus) and pathologic growth patterns (papillary, papillary and solid, papillary and tubular) in 10 patients with CPPs.
- Correlation of imaging features with surgical and follow-up data.
Main Results:
- Pediatric CPPs typically presented as homogeneous, mottle-like masses with hydrocephalus and a papillary growth pattern.
- Adult CPPs showed more varied locations and sizes, with some exhibiting heterogeneous enhancement and combined papillary and solid/tubular growth patterns.
- No recurrences were observed during a median follow-up of 21.3 months.
Conclusions:
- CPPs can exhibit unusual radiologic findings that may complicate preoperative diagnosis.
- Atypical imaging features in CPPs are associated with combined pathologic growth patterns.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
