Is this cyst.?

MRI Analysis - Pelvic MRI (T2-weighted Coronal)
Patient: TEST SAPNA, Female, 23 years old
What is Seen on This MRI?
Yes, the bright (hyperintense) structures you are asking about are consistent with cystic lesions - specifically, they appear to be ovarian follicular cysts / follicles in the right ovary/adnexa.
Key Findings:
| Feature | What is Seen |
|---|---|
| Sequence | T2-weighted MRI (fluid appears bright/white) |
| Location | Right ovary / right adnexa |
| Appearance | Multiple small, round, well-defined, markedly bright structures clustered together |
| Signal | Uniformly hyperintense = simple fluid content |
| Morphology | Small discrete fluid-filled cysts within ovarian tissue |
Most Likely Diagnoses (in a 23-year-old female):
-
Normal Physiological Ovarian Follicles - the most common and most likely explanation. It is completely normal for ovaries to contain multiple fluid-filled developing follicles visible on MRI.
-
Polycystic Ovarian Morphology (PCOM) / PCOS - if there are 20+ small follicles arranged peripherally ("string of pearls" pattern) with increased ovarian volume, this could suggest polycystic ovary syndrome. However, PCOS requires clinical correlation with:
- Irregular menstrual cycles
- Hormonal findings (elevated androgens)
- Clinical symptoms (acne, hirsutism, weight gain)
-
Simple Ovarian Cysts - benign, thin-walled, fluid-only cysts with no internal complexity.
What Makes It Reassuring (Benign Features)?
- The cysts are small and uniform
- The signal is uniformly bright with no dark internal debris, thick walls, or solid nodules
- There is no evidence of complex features (no septations or solid components visible here) that would suggest malignancy
Important Note
This is a preliminary image interpretation only. A radiologist's formal report is required for diagnosis, and clinical correlation with symptoms, menstrual history, and hormone levels (LH, FSH, testosterone, AMH) is essential - especially to distinguish normal follicles from polycystic ovarian morphology.

Updated MRI Analysis - Multi-sequence View (TEST SAPNA, F 23Y)
This second image confirms the findings across two different sequences, which is very helpful.
What's Confirmed on These Sequences:
| Sequence | Finding |
|---|---|
| T2 FSE Coronal (left) | Multiple bright (hyperintense) small cysts in right ovary - ~5-9 mm each |
| STIR Coronal (middle) | Same cysts remain bright even with fat suppression - confirms they are truly fluid-filled, not fat |
The STIR sequence is key - it suppresses fat signal, so anything that stays bright is confirmed to be water/fluid based, not fatty tissue. This is very reassuring - these are simple fluid cysts.
Recommended Blood Tests for PCOS / Ovarian Cysts Workup
Given this MRI in a 23-year-old female, these are the standard blood tests to order:
Hormonal Panel
| Test | What It Checks |
|---|---|
| LH / FSH (Day 2-3 of cycle) | LH:FSH ratio >2:1 suggests PCOS |
| Total & Free Testosterone | Elevated in PCOS (hyperandrogenism) |
| DHEAS | Adrenal androgen - raised in PCOS |
| Prolactin | Rule out hyperprolactinemia |
| TSH | Rule out thyroid dysfunction causing irregular cycles |
| AMH (Anti-Müllerian Hormone) | Elevated in PCOS; reflects follicle count |
| Estradiol (E2) | Baseline ovarian function |
| 17-OH Progesterone | Rule out congenital adrenal hyperplasia |
Metabolic Panel (PCOS has metabolic implications)
| Test | Reason |
|---|---|
| Fasting glucose + Insulin | Insulin resistance is common in PCOS |
| HOMA-IR (calculated) | Insulin resistance index |
| Fasting lipid profile | Dyslipidemia common in PCOS |
| HbA1c | Long-term glucose regulation |
When to Collect?
- Day 2 or Day 3 of the menstrual cycle is ideal for LH, FSH, and Estradiol
- AMH, Testosterone, Prolactin, TSH can be done any day
PCOS Diagnosis (Rotterdam Criteria)
Requires 2 of 3:
- Irregular/absent periods
- Clinical or biochemical signs of excess androgens (acne, hair growth, high testosterone)
- Polycystic ovarian morphology on imaging (which this MRI suggests)
Note: These blood test recommendations are for informational/educational purposes. The treating gynecologist or endocrinologist should direct the actual workup based on clinical history and symptoms.
3 rd day of menstrual cycle
Since the patient is on Day 3 of her menstrual cycle, this is actually the ideal time to collect most hormonal tests. Here is the complete, prioritized blood test panel:
Day 3 Blood Tests - TEST SAPNA (F, 23Y)
✅ MUST DO TODAY (Day 3 is optimal)
| Test | Normal Range (Day 3) | Significance |
|---|---|---|
| FSH | 3-10 IU/L | Low FSH = poor ovarian reserve; High = premature failure |
| LH | 2-8 IU/L | LH:FSH ratio >2:1 or >3:1 = strongly suggests PCOS |
| Estradiol (E2) | 25-75 pg/mL | Should be low on Day 3; high = poor reserve |
| Total Testosterone | 15-70 ng/dL | Elevated = hyperandrogenism (PCOS) |
| Free Testosterone | 0.3-1.9 ng/dL | More sensitive for PCOS than total |
| Prolactin | 2-29 ng/mL | Rule out prolactinoma |
| TSH | 0.5-4.5 mIU/L | Rule out thyroid disease |
✅ CAN BE DONE TODAY (any day of cycle)
| Test | Significance |
|---|---|
| AMH | Best marker for PCOS & ovarian reserve - elevated in PCOS (often >4-5 ng/mL) |
| DHEAS | Adrenal androgen excess |
| 17-OH Progesterone | Rule out CAH (congenital adrenal hyperplasia) |
| Fasting Insulin + Glucose | Insulin resistance (draw fasting) |
| HOMA-IR | Calculated: (Fasting insulin × Fasting glucose) / 405 - >2.5 = insulin resistant |
| Fasting Lipid Profile | Cholesterol, TG, HDL, LDL |
| HbA1c | Metabolic screening |
🔑 Key Ratio to Watch
LH : FSH ratio
- Normal = ~1:1
- >2:1 on Day 3 = highly suggestive of PCOS
- Classic PCOS pattern: LH ↑↑, FSH normal or low
Important Instructions for Patient
- Blood draw should be fasting (8-10 hours) - covers glucose and insulin too
- Collect early morning (hormones peak in AM)
- Note exact Day 3 on the lab form
- AMH does NOT require fasting and can be added to the same draw
This is a strong workup. The MRI findings + these Day 3 hormones + AMH will give a very clear picture of whether this is PCOS, normal follicular development, or another cause. Final interpretation should be done by the treating gynecologist/endocrinologist.
