Isolated retinal astrocytic hamartoma with 7-year follow-up: A case report
Bibliographic record
Abstract
RATIONALE: Retinal astrocytic hamartoma (RAH) is a rare benign tumor originating from astrocytic cells located in the neural cell layer of the retina. It is commonly seen in patients with phakomatoses such as tuberous sclerosis complex or neurofibromatosis, rarely as an isolated retinal mass. This lesion is usually asymptomatic; however, these located in the area of the optic nerve, macula, or exhibiting the features of exudation, neovascularization may present visual disturbances and decreased visual acuity. PATIENT CONCERNS: We present a rare case of a 15-year-old boy, with no significant past medical history, whose cause of visual disturbances turned out to be isolated RAH. DIAGNOSES: Based on the results of color images of the fundus, fluorescein angiography as well as the analysis of magnetic resonance imaging, the patient was diagnosed with RAH. INTERVENTIONS: Additionally an B-scan ultrasonography, static and kinetic perimetry were performed. OUTCOMES: Fundoscopic examination showed a unilateral yellowish, well-circumscribed, mulberry-like lesion with a wide base, located in inferosnasal quadrant, in the vinicity of the optic nerve. The patient underwent neurological, pediatric, and genetic evaluations that excluded other pathological findings or underlying systemic disease. LESSONS: The prognosis for RAH is generally good, however, the lesion requires regular ophthalmologic follow-up to rule out the progression of the tumor mass. The patient 7-year follow-up history is without evidence of tumor growth, local or general deterioration of the condition.

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.
