Endometriosis: Clinical Presentation, Diagnostic Evaluation, Management, and Outcomes – A Case Report

Abstract

Endometriosis is a chronic estrogen-dependent gynecological disorder characterized by the presence of functional endometrial tissue outside the uterine cavity. It commonly affects women of reproductive age and presents with chronic pelvic pain, dysmenorrhea, dyspareunia, infertility, and menstrual irregularities. Delayed diagnosis may significantly impair quality of life and reproductive health.

We present the case of a 29-year-old female who presented with progressively worsening dysmenorrhea, chronic pelvic pain, and infertility for 3 years. Clinical examination, ultrasonography, and laparoscopic evaluation confirmed ovarian endometriosis with pelvic adhesions. The patient was managed with hormonal therapy, laparoscopic excision of endometriotic lesions, pain management, and fertility counseling, resulting in significant symptomatic improvement.

This case highlights the importance of early recognition, multidisciplinary management, and individualized treatment strategies in improving outcomes among patients with endometriosis.

Introduction

Endometriosis is a chronic inflammatory gynecological condition in which endometrial glands and stroma are found outside the uterine cavity. The disease most commonly involves the ovaries, pelvic peritoneum, uterosacral ligaments, pouch of Douglas, and fallopian tubes, although extra-pelvic involvement may also occur.

The condition affects approximately 10% of women of reproductive age and is strongly associated with chronic pelvic pain and infertility. Despite its high prevalence, diagnosis is often delayed because symptoms may overlap with other gynecological or gastrointestinal disorders.

Several mechanisms have been proposed in the pathogenesis of endometriosis, including retrograde menstruation, coelomic metaplasia, immune dysfunction, genetic susceptibility, and hormonal influences.

Important risk factors include:
• Early menarche
• Short menstrual cycles
• Heavy menstrual bleeding
• Family history of endometriosis
• Delayed childbearing
• Nulliparity
• Estrogen exposure
• Autoimmune predisposition

Common symptoms include:
• Severe dysmenorrhea
• Chronic pelvic pain
• Dyspareunia
• Infertility
• Pain during defecation or urination
• Menstrual irregularities
• Fatigue and reduced quality of life

Early diagnosis and individualized management are essential for symptom control, fertility preservation, and prevention of disease progression.

Case Report

Patient History

A 29-year-old married female presented to the gynecology outpatient department with:

• Severe dysmenorrhea for 5 years
• Chronic lower abdominal and pelvic pain
• Pain during sexual intercourse
• Difficulty conceiving for 3 years
• Increased pelvic discomfort during menstruation

The pain had progressively worsened over the past two years and significantly affected her daily activities and emotional well-being.

There was no history of:
• Previous pelvic surgery
• Tuberculosis
• Sexually transmitted infections
• Chronic systemic illness
• Malignancy

Family history revealed that the patient’s elder sister had previously been diagnosed with endometriosis.

Clinical Examination

General Examination

• Afebrile
• Pulse rate: 80/min
• Blood pressure: 116/74 mmHg
• Body mass index: 23 kg/m²
• Systemically stable

Gynecological Examination

Pelvic examination revealed:
• Tenderness in the posterior fornix
• Restricted uterine mobility
• Left adnexal tenderness
• Nodularity along uterosacral ligaments
• Mild pelvic fullness

No abnormal vaginal discharge or cervical lesions were noted.

Clinical Evaluation

Differential Diagnosis

The following conditions were considered:
• Pelvic inflammatory disease
• Adenomyosis
• Ovarian cyst
• Irritable bowel syndrome
• Uterine fibroids
• Endometriosis

The cyclic nature of pain, infertility, dysmenorrhea, and pelvic tenderness strongly suggested endometriosis.

Investigations

Laboratory Findings

• Hemoglobin: Mild anemia detected
• White blood cell count: Normal
• CA-125: Mildly elevated
• Thyroid profile: Normal
• Hormonal profile: Within normal limits

Ultrasonography

Transvaginal ultrasonography revealed:

• Left ovarian endometrioma measuring 4 cm
• Thick-walled cyst with homogeneous low-level internal echoes
• Mild pelvic adhesions

Magnetic Resonance Imaging (MRI)

MRI pelvis demonstrated:
• Ovarian endometriotic cyst
• Pelvic adhesions
• Thickening of uterosacral ligaments
• Features suggestive of deep infiltrating endometriosis

Diagnostic Laparoscopy

Laparoscopic evaluation revealed:
• Chocolate cyst involving left ovary
• Multiple endometriotic implants
• Dense pelvic adhesions
• Obliteration of pouch of Douglas
• Peritoneal inflammatory lesions

Histopathological examination confirmed endometrial glands and stroma outside the uterine cavity.

Diagnosis

Based on clinical presentation, imaging findings, laparoscopic evaluation, and histopathology, a diagnosis of Moderate-to-Severe Pelvic Endometriosis with Ovarian Endometrioma was established.

Management and Outcome

Initial Management

The patient was counseled regarding:
• Nature of the disease
• Chronicity and recurrence risk
• Fertility implications
• Lifestyle modifications
• Importance of long-term follow-up

Medical Management

The patient received:
• Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief
• Combined oral contraceptive therapy
• Hormonal suppression therapy
• Iron supplementation for anemia

Surgical Management

Laparoscopic surgery was performed, including:
• Excision of endometriotic implants
• Adhesiolysis
• Ovarian cystectomy
• Restoration of pelvic anatomy

Follow-Up and Clinical Course

At 1 Month

• Significant reduction in pelvic pain
• Improved menstrual symptoms
• Better sleep and daily functioning

At 3 Months

• Marked reduction in dysmenorrhea
• Improvement in quality of life
• No significant recurrence of pelvic pain

At 6 Months

• Stable clinical condition
• Improved emotional well-being
• Fertility counseling continued

The patient remained under regular gynecological follow-up.

Discussion

Pathophysiology

Endometriosis is a multifactorial disease involving hormonal, immunological, inflammatory, and genetic mechanisms.

Important pathological mechanisms include:
• Retrograde menstruation with implantation of endometrial cells
• Chronic inflammatory response
• Estrogen-dependent proliferation
• Angiogenesis and fibrosis
• Adhesion formation
• Neurogenic inflammation causing chronic pain

The inflammatory microenvironment contributes significantly to pain, infertility, and disease progression.

Epidemiology

Important epidemiological features include:
• Affects nearly 1 in 10 women of reproductive age
• Commonly diagnosed between 25–35 years
• Frequently associated with infertility
• Strong familial predisposition
• Significant socioeconomic and psychological burden

Endometriosis remains underdiagnosed globally due to variability in symptoms and delayed recognition.

Clinical Manifestations

Common manifestations include:
• Dysmenorrhea
• Chronic pelvic pain
• Dyspareunia
• Infertility
• Dyschezia
• Menorrhagia
• Fatigue

Commonly affected anatomical sites include:
• Ovaries
• Pelvic peritoneum
• Uterosacral ligaments
• Rectovaginal septum
• Fallopian tubes

Diagnostic Considerations

Diagnosis is often delayed because symptoms may mimic other gynecological or gastrointestinal conditions.

Important diagnostic modalities include:

1. Pelvic examination
2. Transvaginal ultrasonography
3. MRI pelvis
4. Serum CA-125
5. Diagnostic laparoscopy with biopsy

Laparoscopy remains the gold standard for definitive diagnosis.

Treatment Modalities

Conservative Management

Supportive measures include:
• Lifestyle modification
• Exercise and stress reduction
• Nutritional counseling
• Psychological support

Pharmacological Therapy

Medical treatment options include:
• NSAIDs
• Combined oral contraceptives
• Progestins
• Gonadotropin-releasing hormone agonists
• Aromatase inhibitors
• Hormonal suppression therapy

Surgical Management

Surgery may be required for:
• Severe pain
• Large endometriomas
• Adhesions
• Infertility
• Failure of medical therapy

Laparoscopic excision remains the preferred surgical approach.

Complications

Potential complications include:
• Chronic pelvic pain syndrome
• Infertility
• Ovarian cyst rupture
• Adhesion formation
• Bowel and bladder involvement
• Psychological distress
• Reduced quality of life

Delayed treatment may result in progressive disease and reproductive complications.

Prognosis

The prognosis depends upon:
• Severity of disease
• Early diagnosis
• Response to hormonal therapy
• Surgical outcomes
• Fertility status
• Long-term follow-up adherence

Although recurrence is common, early multidisciplinary management significantly improves symptom control and quality of life.

Conclusion

Endometriosis is a chronic inflammatory gynecological disorder that can significantly affect reproductive health, psychological well-being, and quality of life if left untreated. Early recognition of dysmenorrhea, chronic pelvic pain, infertility, and cyclic symptoms is essential for timely diagnosis.

This case highlights the importance of imaging evaluation, laparoscopic confirmation, individualized hormonal therapy, and surgical management in achieving favorable clinical outcomes. Long-term follow-up, fertility counseling, and patient education remain critical components in the comprehensive management of endometriosis.
