Malignant Lymphoproliferative Disorders Extending into the Orbit from the Paranasal Sinuses
Bibliographic record
Abstract
BACKGROUND/AIMS: To describe the clinical features, imaging, histologic spectrum, treatment and prognosis of patients with malignant orbital lymphoproliferative disorders extending from the paranasal sinuses. METHODS: Patients were culled from the University of British Columbia Orbit Clinic (1977-2004) and their clinical charts, imaging and pathology specimens reviewed. RESULTS: The study included 6 patients with non-Hodgkin's lymphoma (NHL) and 5 multiple myeloma (MM). Orbital symptoms at presentation were periorbital swelling, diplopia, proptosis and pain. Major clinical findings were globe displacement, abnormal ocular movements, periorbital fullness, fifth nerve hypoesthesia and inflammatory signs. Imaging showed a soft tissue mass in one or more sinuses invading the orbit. Three NHL patients were still alive at last follow-up with one patient lost to follow-up. Two NHL patients and all MM died. CONCLUSION: Presenting symptoms of malignant orbital lymphoproliferative disorders extending from the paranasal sinuses include mass effect occasionally with infiltrative and inflammatory characteristics accompanied by symptoms of sinus disease. On imaging, a soft tissue mass in the sinuses and orbit with bone destruction is commonly seen. Biopsy is essential for conclusive diagnosis. Treatment should be initiated promptly as local symptoms are frequently relieved and survival is possible, especially in cases of NHL.

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.
