• Cardiomediastinal silhouette is within normal size limits.
• Mild linear/band-like opacity in the left lower zone (retrocardiac region), likely subsegmental atelectatic/fibrotic streak.
• No focal lobar air-space consolidation.
• No pleural effusion or pneumothorax.
• No acute osseous abnormality seen in the visualized bony thorax.

1. Mild left basilar linear atelectatic/fibrotic change (small plate-like opacity).
2. No pleural effusion or pneumothorax.
3. No cardiomegaly or overt acute cardiopulmonary abnormality.

Follow-up & Management — Post Right Oophorectomy for Mature Cystic Teratoma (Dermoid Cyst)

Histopathology Summary

• Cyst 6×4×1.5 cm lined by keratinised stratified squamous epithelium with ecrine/sebaceous glands, adipose tissue, smooth muscle (classic dermoid/MCT features)
• Adjacent ovary: Corpus luteum with theca & granulosa cells + cortical stromal hyperplasia
• No malignancy confirmed — fully benign, complete excision (right oophorectomy)

Immediate Post-operative Care (First 4–6 weeks)

Hormonal Considerations

• Right ovary removed but left ovary is intact → patient retains ovarian function, menstrual cycles should continue normally
• Monitor for irregular cycles or signs of premature ovarian insufficiency (unlikely with one ovary intact at age 30)
• If cycles become irregular → check FSH, LH, AMH, E2 (ovarian reserve assessment)

Fertility Counselling (Important — 30Y Female)

• One ovary remaining → fertility is generally preserved
• AMH (Anti-Müllerian Hormone) and AFC (Antral Follicle Count) via ultrasound at 3 months post-op to assess ovarian reserve
• If planning pregnancy, advise no specific delay beyond routine post-op recovery (3–6 months)
• Counsel regarding ~10–15% risk of contralateral (left) ovary developing MCT — bilateral MCT is well-documented

Surveillance & Follow-up Schedule

Per Bailey & Love's (p. 1613): TVUS is the mainstay surveillance tool with high sensitivity and specificity for differentiating benign from malignant adnexal masses.

Tumour Markers — Baseline (Recommended)

• CA-125 — rule out epithelial ovarian component
• AFP (Alpha-fetoprotein) — to exclude immature/malignant germ cell component
• Beta-hCG — rule out gestational/choriocarcinoma elements
• LDH — if any doubt about dysgerminoma

Red Flag Symptoms — Advise Patient to Return Immediately If:

• New pelvic pain or pressure (left side — possible contralateral dermoid/torsion)
• Sudden severe abdominal pain (ovarian torsion of remaining ovary)
• Abdominal distension, weight loss, loss of appetite
• Irregular or absent periods persisting beyond 3 months
• Fever / wound discharge (post-op infection)

Key Counselling Points for Patient

1. Benign condition — cured by surgery. No further cancer treatment needed.
2. Left ovary is intact — menstrual and reproductive function expected to be normal.
3. Small risk (~10–15%) of a similar cyst developing in the left ovary — annual USS is therefore important.
4. If fertility is desired, plan within a reasonable timeframe given single-ovary status.
5. No dietary or lifestyle restrictions specific to this diagnosis.

Summary: This is a benign, completely excised mature cystic teratoma. No adjuvant therapy is required. Management is focused on post-op recovery, ovarian reserve assessment, fertility counselling, and annual TVUS surveillance of the contralateral left ovary for at least 3–5 years.
