Spontaneous Subdural Hematoma Secondary to Influenza Vaccine-Induced Immune Thrombocytopenia
Bibliographic record
Abstract
Influenza vaccine-induced immune thrombocytopenia (ITP), though rare, can present with a wide spectrum of clinical manifestations, ranging from mild asymptomatic thrombocytopenia to life-threatening complications, such as gastrointestinal (GI) bleeding, diffuse alveolar hemorrhage (DAH), or intracranial hemorrhage (ICH), particularly when platelet count drops below a critical level of less than 5,000/µL. We report a rare case of spontaneous subdural hematoma (SDH) due to severe ITP following the influenza vaccine that showed a dramatic response to high-dose methylprednisolone and intravenous immunoglobulin (IVIG), with platelet count returning to normal and complete resolution of symptoms by the third day of therapy initiation.

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.
