Case Presentation Guide: Adenomyosis with Bilateral Endometrioma and Dense Pelvic Adhesions

1. PATIENT SUMMARY (Case Overview)

2. MAIN DIAGNOSIS - What it is and Why

Adenomyosis

• More common in multiparous patients (this patient is G2P2) in their later reproductive years
• Often coexists with uterine leiomyoma and/or endometriosis
• Prevalence estimated at ~30% of reproductive-age patients

Bilateral Endometrioma

1. Ovaries (this patient - bilateral)
2. Uterine ligaments
3. Rectovaginal septum
4. Cul-de-sac (pouch of Douglas)
5. Pelvic peritoneum
6. Serosa of large and small bowel and appendix

Dense Pelvic Adhesions Involving the Rectum

3. WHY WAS SURGERY DONE?

4. HOW WAS THE DIAGNOSIS MADE? (Diagnostic Pathway)

Step 1 - Clinical History (Suggestive)

• Cyclic pelvic pain starting up to 2 weeks before menses - pathognomonic for endometriosis/adenomyosis
• Dysmenorrhea - severe, worsening over time
• Dyschezia (painful defecation around menses) - indicates rectal/rectovaginal involvement
• Deep dyspareunia - posterior cul-de-sac or uterosacral ligament disease
• Multiparous status (risk factor for adenomyosis)

Step 2 - Physical Examination

• Bimanual and rectovaginal exam may reveal:
  • Uterosacral nodularity and focal tenderness
  • Fixed retroverted uterus (from posterior adhesions pulling the uterus back)
  • Adnexal fullness bilaterally (the endometriomas)
  • Laterally deviated cervix or uterus from fibrosis

Step 3 - Imaging

• First-line imaging
• Endometriomas appear as homogeneous, hemorrhagic "ground-glass" cysts that fail to resolve after 1-2 menstrual cycles
• In adenomyosis: myometrial heterogeneity, blurring of the junctional zone (endometrium-myometrium border), myometrial "cysts"

• Higher sensitivity and specificity than ultrasound
• Better for adenomyosis: shows junctional zone thickening > 12 mm (highly suggestive of adenomyosis), and adenomyomas as focal asymmetric myometrial masses
• Better for deep infiltrating endometriosis and rectal involvement

Step 4 - Laboratory

• CA-125 may be elevated but is nonspecific and nonsensitive - cannot confirm or exclude endometriosis alone

Step 5 - Definitive Diagnosis (Gold Standard)

• "Powder-burn" or "gunshot" lesions - black/dark brown nodules with surrounding fibrosis (older disease)
• Red flame lesions - red/petechial implants (active, early disease)
• Chocolate cysts on both ovaries (bilateral endometriomas)
• Dense adhesions binding the rectum to the posterior uterus
• Peritoneal windows; uterosacral ligament nodularity

5. DIFFERENTIAL DIAGNOSES

6. MANAGEMENT

Medical Management (Pre-surgical or for non-surgical candidates)

• Combined oral contraceptive pills (OCP) - cyclic or continuous regimens
• NSAIDs for pain

• High-dose progestins (medroxyprogesterone acetate, norethindrone acetate) - as effective as GnRH analogs
• Levonorgestrel IUS (Mirena) - effective for endometriosis-related chronic pain
• GnRH agonists (e.g., leuprolide) with add-back therapy (norethindrone acetate ± low-dose estrogen) - limit to 8-12 months due to bone loss

• Danazol (androgenic, side effect-heavy; increasingly less used)
• Aromatase inhibitors (for refractory cases)

Surgical Management

• Lower recurrence of the cyst
• Lower recurrence of dysmenorrhea, dyspareunia, and nonmenstrual pelvic pain
• Reduced need for further surgery

Introduction of Each Disease Condition — Correlated to the Patient

CONDITION 1: ADENOMYOSIS

Textbook Introduction

"Adenomyosis is defined as the presence of endometrial glands and stroma within the myometrium and is considered a variant of endometriosis. There is a molecular interaction between the displaced endometrial cells and the adjacent myometrial cells, which causes hypertrophy of the myometrium and inflammation. In some patients, this results in a heavier, enlarged uterus. The prevalence of adenomyosis is estimated around 30% of patients of reproductive age with increasing prevalence in the later reproductive years. It is found more commonly in multiparous patients compared with nulliparous patients. Symptoms include heavy, painful periods, irregular bleeding, painful intercourse, and noncyclic pelvic pain." — Sabiston Textbook of Surgery

CONDITION 2: BILATERAL ENDOMETRIOMA (Endometriosis)

Textbook Introduction

"Endometriosis is defined by the presence of 'ectopic' endometrial tissue at a site outside of the uterus. It occurs in the following sites, in descending order of frequency: (1) ovaries, (2) uterine ligaments, (3) rectovaginal septum, (4) cul-de-sac, (5) pelvic peritoneum, (6) serosa of the large and small bowel and appendix. The disorder is principally a disease of females in active reproductive life, most often in the third and fourth decades, and affects approximately 10% of females. Endometriosis can have significant clinical consequences; it often causes infertility, dysmenorrhea, pelvic pain, and other problems." — Robbins, Cotran & Kumar - Pathologic Basis of Disease

"Endometriosis is defined by the presence of endometrial glands and stroma in a location outside the uterus. It occurs in as many as 10% of women in their reproductive years and in nearly half of women with infertility. It is frequently multifocal and often involves pelvic structures." — Robbins & Kumar Basic Pathology

CONDITION 3: DENSE PELVIC ADHESIONS INVOLVING THE RECTUM

Textbook Introduction

"Clinical signs and symptoms usually include severe dysmenorrhea, dyspareunia, and pelvic pain due to intrapelvic bleeding and periuterine adhesions. Fibrosis resulting from endometriosis can cause a fixed retroverted uterus or laterally deviated cervix or uterus." — Robbins, Cotran & Kumar - Pathologic Basis of Disease

"Deep infiltrating endometriosis invading the peritoneal surface with a depth of at least 5 mm. Most patients with ovarian endometriotic cysts or deep endometriosis also have peritoneal disease. Digestive system infiltrating endometriosis often occurs in the intestines, especially the sigmoid rectum. DSIE-related cyclic changes, recurrent inflammation and oxidative stress promote repeated tissue injury and repair (ReTIAR) mechanisms in the lesions, accelerating fibril formation." — Literature (Yin W et al., J Cell Mol Med, 2023)

COMBINED PATIENT NARRATIVE (For Your Introduction Slide)

"This patient is a G2P2 reproductive-age female presenting with chronic cyclic pelvic pain, a constellation that reflects three simultaneously occurring, mechanistically linked conditions. Adenomyosis, defined as endometrial glands and stroma within the myometrium (Robbins Basic Pathology), explains her cyclically-timed pain, uterine enlargement, and heavy bleeding - a pattern strongly associated with multiparous women like her. Bilateral endometriosis on the ovaries, forming endometriomas, represents the most common anatomical site of endometriosis and indicates advanced-stage disease (Robbins, Cotran & Kumar). The ectopic tissue bleeds cyclically with every menstrual cycle, and over time, recurrent intrapelvic bleeding triggered a cycle of inflammation, fibrosis, and adhesion formation. This explains the third finding: dense pelvic adhesions binding the rectum to the posterior uterus - the anatomical consequence of years of posterior compartment endometriosis, and the source of her dyschezia and deep, fixed pelvic pain."
