Clinical and cytogenetic analysis of an intracranial inflammatory myofibroblastic tumor induced by a ventriculoperitoneal shunt
Bibliographic record
Abstract
The authors report the first case of an intracranial inflammatory myofibroblastic tumor (IMT) associated with the placement of a ventriculoperitoneal shunt, which occurred in a 7-year-old boy. Neuroradiological features showed a mass surrounding the ventricular catheter. The lesion was completely resected. Histological study revealed the mass to be an IMT. The patient's postoperative course was complicated by a local recurrence requiring a second surgery. Cytogenetic analysis of the sample by comparative genome hybridization revealed several chromosomal amplifications and regional losses. The occurrence of IMT in the CNS has rarely been reported. For treatment of this condition, the authors recommend a total removal of the shunt with a mass excision to prevent local recurrence.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
