Pelvic Pain: Or something else? Differential Diagnosis

Acute pelvic pain

Congenital malformations, deformities, and chromosomal abnormalities (Q00-Q99).

  • Infected urachal fistula (Urachus: duct extending from the umbilicus to the urinary bladder and usually closed at birth. In rare cases, the connection may persist and fill with fluid (called a urachal cyst)).

Cardiovascular system (I00-I99).

  • Pelvic vein syndrome, unspecified

Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).

  • Acute appendicitis (“appendicitis”).
  • Bride (adhesion strand (Bride), this jams the intestine).
  • Diverticulitis – disease of the colon in which inflammation forms in protrusions of the mucosa (diverticula).
  • Inguinal hernia (inguinal hernia) or other forms of hernia (hernia), possibly incarcerated (pinched).
  • Proctitis (rectal inflammation)

Musculoskeletal system and connective tissue (M00-M99)

  • Fibrosis (abnormal connective tissue proliferation), unspecified.
  • Psoas abscess (collection of pus in the psoas ligament).
    • Primary psoas abscess: this arises from hematogenous dissemination (seeding via the bloodstream) when the primary site is unclear and primarily affects younger patients and. (75-90% of cases Staphylococcus aureus).
    • Secondary psoas abscess: this arises from direct infection spread of adjacent organs (80% of cases are gastrointestinal cause (appendicitis, diverticulitis, colon cancer, Crohn’s disease). Other causes include secondary spondylitis, tuberculous spondylitis, pyogenic sacroiliitis and infected hip joint endoprostheses.

Neoplasms – tumor diseases (C00-D48).

  • Cervical carcinoma (cervical carcinoma).
  • Ovarian carcinoma (ovarian cancer)
  • Ovarian cyst (fluid-filled cavity in the ovary), rupture (tearing) or torsion (twisting).

Pregnancy, childbirth and puerperium (O00-O99).

Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99).

  • Adnexitis – inflammation of the fallopian tubes and ovary.
  • Endometriosis – occurrence of endometrium (lining of the uterus) outside the uterus, for example, in or on the ovaries (ovaries), tubes (fallopian tubes), urinary bladder, or intestines
  • Urinary tract infection
  • Prostatitis (inflammation of the prostate)

Other causes

  • Pelvic abscess, unspecified
  • Dislocated (displaced) intrauterine device (IUD).
  • Functional pelvic pain with psychosexual origin.
  • Referred pain, unspecified (e.g., bowel spasms).
  • See also “Abdominal pain due to medication.”

Chronic pelvic pain

Disease-related causes

Cardiovascular system (I00-I99)

  • Pelvic vein syndrome, unspecified

Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).

  • Diverticulitis – disease of the large intestine in which inflammation forms in protrusions of the mucosa (diverticula).
  • Inflammatory bowel disease (IBD), unspecified (eg Crohn’s disease, ulcerative colitis).
  • Ileus (intestinal obstruction)
  • Irritable bowel syndrome (IBS)

Musculoskeletal system and connective tissue (M00-M99)

  • Lumbar pain (low back pain), deep
  • Psoas abscess (collection of pus in the psoas ligament).
    • Primary psoas abscess: this arises from hematogenous dissemination (seeding via the bloodstream) when the primary site is unclear and primarily affects younger patients and. (75-90% of cases Staphylococcus aureus).
    • Secondary psoas abscess: this arises from direct infection spread of adjacent organs (80% of cases gastrointestinal causes (appendicitis, diverticulitis, colon cancer, Crohn’s disease) before. Other causes include secondary spondylitis, tuberculous spondylitis, pyogenic sacroiliitis and infected hip joint endoprostheses.

Neoplasms – tumor diseases (C00-D48).

  • Cervical carcinoma (cervical cancer).
  • Colon carcinoma (cancer of the large intestine), distal
  • Fibroma – benign growth of connective tissue.
  • Ovarian cancer (ovarian cancer)
  • Ovarian cyst – fluid-filled cavity in the ovary.

Psyche – nervous system (F00-F99; G00-G99)

  • Chronic pelvic pain in men (synonyms: anogenital symptom complex, chronic abacterial prostatitis, chronic pelvic pain syndrome (CPPS), chronic pelvic pain syndrome, prostatodynia, vegetative urogenital syndrome) – the cause of the complaints is vegetative dysregulation triggered by stress (CPPS is a component of prostatitis syndrome: see. u. Prostatitis (prostatitis)/classification).
  • Chronic pelvic pain syndrome – pain for at least 6 months in the organs and structures of the small pelvis; this is a diagnosis of exclusion ie that, for example .inflammation, endometriosis or tumors must be excluded.
  • Pelvipathy (lower abdominal pain) in women – due to very different causes, which can be somatic (physical) as well as psychological:
    • Pelvipathy (pelvipathia; chronic pelvic pain (CPP), hysteralgia). This is chronic (= lasting longer than six months) lower abdominal pain in women. The pain is crampy and occurs independently of sexual intercourse and menstrual cycle.
    • Pelvipathia vegetativa (synonyms: parametropathia spastica, pelvic congestion) – vegetative dystonia (disorder of conduction in the nervous system) manifested in the pelvis in vegetative lability (susceptibility to stress).
  • Vulvodynia – insensations and pain of the external primary sex organs that last longer than three months without an identifiable cause; complaints are localized or generalized over the entire perineal area (tissue area between the anus and the external sex organs); possibly also present as a mixed form; prevalence (disease frequency) of essential vulvodynia: 1-3%.

Symptoms and abnormal clinical and laboratory findings not classified elsewhere (R00-R99).

  • Deep back pain

Genitourinary system (kidneys, urinary tract – sex organs) (N00-N99)

  • Chronic adnexitis – inflammation of the ovary and fallopian tubes.
  • Chronic interstitial cystitis (IC) – chronic, abacterial cystitis; pain syndrome associated with pelvic pain when the bladder is full, pollakiuria (urge to urinate frequently without increased urination), and urinary urgency.
  • Dysmenorrhea (painful menstruation), primary
  • Endometriosis – occurrence of endometrium (lining of the uterus) outside the uterus, for example, in or on the ovaries (ovaries), tubes (fallopian tubes), urinary bladder or intestine.
  • Genital prolapse – partial or complete prolapse of the vagina (descensus vaginae) and/or uterus (descensus uteri) from the pubic cleft (rima pudendi)
  • Urinary tract infections, recurrent (“recurrent”).
  • Interstitial cystitis (interstitial cystitis, IC; synonym: Hunner’s cystitis) – bladder inflammation of unclear etiology occurring predominantly in women with fibrosis of the bladder muscles, pelvic pain with overfilled bladder, urge incontinence (irritable bladder or overactive (hyperactive) bladder) and development of a shrinking bladder; confirm diagnosis by: Urethrocystoscopy (urethral and bladder endoscopy) and biopsy (tissue sampling) for histology (fine tissue examination) and molecular diagnostics of specific cell proteins.

Other causes

  • Dislocated (displaced) intrauterine device (IUD).
  • Mid-cycle pain (intermenstrual pain) – lower abdominal pain occurring in the middle of a woman’s menstrual cycle, likely due to follicular rupture (ovulation; ovulation)
