Radiation Therapy for Solitary Fibrous Tumor of the Orbit.

Solitary fibrous tumor, formerly also referred to as hemangiopericytoma, is a fibroblastic mesenchymal neoplasm of the orbit that rarely metastasizes but has a propensity for local recurrence. We describe 5 cases of orbital solitary fibrous tumors that were treated with radiation. In 3 patients, radiation therapy was given in the neoadjuvant setting prior to surgery.

Marked Enlargement of a Single Extraocular Muscle: Clinical and Imaging Patterns in the Prediction of Malignancy.

Purpose: To evaluate clinical presentation, imaging patterns, histopathology, and predictors of malignancy in patients with enlargement of a single extraocular muscle.

Methods: Retrospective review, with imaging categorized into 3 groups: single-muscle only (SMO), single excessively-enlarged muscle, and single-muscle with lacrimal gland enlargement (SMLG). Histopathology was classified as specific or nonspecific myositis, atypical thyroid eye disease, malignancy, or other diagnosis.

Metastastic Tumors to the Lacrimal Gland from Distant Primary Cancer.

Purpose: To characterize the clinical, radiological, and pathological features of patients with metastases to the lacrimal gland from distant primaries.

Methods: Multicenter retrospective case series and a review of the literature of cases of metastases to the lacrimal gland.

Results: The authors present 4 cases of lacrimal gland metastases, with the primaries being renal cell (n = 2) and breast (n = 2) carcinoma.

One-stage Intraconal Volume Modification for Exposed and Nonexposed Ball Implants.

Purpose: To assess long-term outcomes and reinterventions for exposed and nonexposed intraconal orbital implants after single-stage socket revisional surgery.

Methods: Retrospective case-note review of patients with exposed or nonexposed orbital ball implants, who underwent a single-stage ball exchange (Group I) or ball removal with dermis-fat graft (Group II); Group I was subdivided as having either exposed (A) or nonexposed (B) implants. Outcomes were compared with similar cohorts undergoing multistage surgery.

Long-Term Outcome of Staged Socket Surgery for Acquired Anophthalmos.

Purpose: To evaluate long-term outcomes of staged volume rehabilitation for acquired anophthalmos.

Methods: Case-note review of patients who had preceding i) eye removal without implant, ii) eye removal with an intraconal implant, but ball-related problems, or iii) removal of exposed implant. Secondary interventions were a) a first-time ball implant, b) dermis-fat graft, c) ball repositioning, d) ball replacement after prior removal, or e) orbital floor implantation.
