Subperiosteal Orbital Hematoma: A Rare Clinical Manifestation of Sickle Cell Disease - A Case Report
Bibliographic record
Abstract
Sickle cell disease (SCD), an inherited vaso-occlusive disorder, results in recurrent painful episodes and a variety of serious systemic complications that can lead to severe disabilities and even death. Here, we report a case of a 19-year-old African American patient with homozygous sickle cell trait who presented with right upper lid edema and ptosis, 3 days after his admission to the hospital following a sickle cell crisis. Initially, mistaken as a superinfection in the context of his disease, a diagnosis of orbital abscess was made. Intravenous antibiotics and a proper treatment plan were set accordingly. Only after extensive clinical and radiological examinations, it turned out to be an acute subperiosteal orbital hematoma, a rare clinical manifestation of SCD. The aim of our case report was to highlight the difference in orbital presentation between osteomyelitis and subperiosteal hematoma, as well as spreading awareness among medical professionals and especially ophthalmologists for this rare presentation of orbital wall infarction, as the initial differential diagnosis of SCD patients with ocular involvement.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
