Abstract

fetched live from OpenAlex

We present a case report of a 21-month-old female patient to highlight magnetic resonance (MR) imaging findings associated with papilledema in a pediatric patient with an intracranial tumor. The MR findings included optic disc elevation, dilated perioptic subarachnoid spaces, optic nerve tortuosity and restricted diffusion in the optic nerve heads, all of which resolved upon resolution of raised intracranial pressure (ICP) and papilledema. The case demonstrates that both conventional and diffusion-weighted MR imaging findings can detect the presence, and follow posttreatment resolution, of increased ICP and papilledema in a pediatric tumor patient. The postoperative resolution of optic disc elevation clearly indicates the intracranial tumor etiology.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
