RIF Mass Approach Algorithm
Here's the algorithm flowchart for approaching a Right Iliac Fossa (RIF) Mass. It covers the three anatomical compartments:

Key Decision Point

"Does the mass disappear on tensing abdominal muscles?"
  • No (persists) → Abdominal Wall Mass
  • Yes (disappears) → Intra-abdominal or Retroperitoneal

1. Abdominal Wall Mass

  • Lipoma, sebaceous cyst, desmoid tumor, hernia (inguinal/femoral), hematoma, abscess
  • Investigations: Ultrasound, CT scan

2. Intra-abdominal Mass

  • Appendicular: appendicular mass/abscess, carcinoma cecum
  • Ileocecal: Crohn's disease, TB ileocecal
  • Gynecological: ovarian cyst, ectopic pregnancy
  • Vascular: iliac artery aneurysm
  • Investigations: USG abdomen, CT abdomen, colonoscopy, barium enema, β-hCG, CA-125, CEA

3. Retroperitoneal Mass

  • Psoas abscess, lymphoma, iliac lymphadenopathy, retroperitoneal sarcoma, pelvic kidney
  • Clinical clue: Resonant on percussion (bowel loops lie anterior)
  • Investigations: CT/MRI abdomen, FNAC/biopsy, IVP
The color coding distinguishes each compartment — blue (abdominal wall), green (intra-abdominal), orange (retroperitoneal) — for quick visual reference at the bedside or in study.
