Differential Diagnosis for Modularity in Right Lower Abdominal Wall with Daily Pain in a 32-Year-Old Female
- Single Most Likely Diagnosis
- Inflammatory bowel disease (IBD) such as Crohn's disease: This condition often presents with chronic abdominal pain, weight loss, and changes in bowel habits. The modularity in the right lower abdominal wall could be indicative of a Crohn's-related complication like a fistula or abscess.
- Other Likely Diagnoses
- Appendicitis: Although appendicitis typically presents acutely, chronic or recurrent appendicitis could cause daily pain and modularity in the right lower abdomen if an appendicolith or other appendiceal pathology is present.
- Ovarian cyst or torsion: Given the patient's gender, ovarian pathology is a consideration. An ovarian cyst could cause chronic pain and a palpable mass, while torsion would present more acutely.
- Diverticulitis: Although less common in younger patients, diverticulitis can cause chronic pain and modularity in the abdominal wall, especially if there's an associated abscess or fistula.
- Do Not Miss Diagnoses
- Ectopic pregnancy: Although less likely given the daily nature of the pain, an ectopic pregnancy can present with chronic pain and a palpable mass if the ectopic pregnancy is slowly leaking or if there's a large hematoma.
- Ovarian cancer: While rare in young women, ovarian cancer can cause chronic abdominal pain, weight loss, and a palpable mass.
- Intestinal obstruction: Partial obstruction can cause chronic pain and could lead to modularity if there's associated wall thickening or an abscess.
- Rare Diagnoses
- Desmoid tumor: A rare, benign tumor that can occur in the abdominal wall, desmoid tumors can cause chronic pain and a palpable mass.
- Abdominal wall endometriosis: Endometriosis can implant in the abdominal wall, causing cyclic pain and a palpable mass, although this is less common.
- Lymphoma: Both Hodgkin's and non-Hodgkin's lymphoma can cause abdominal pain and masses, although these would typically be more systemic in presentation.
