Differential Diagnosis
- Single most likely diagnosis:
- Ovarian cyst: The CT scan shows a cyst-like low-density solid lesion in the left adnexa, which is unchanged compared to the prior study, making it most likely represent a benign ovarian cyst.
- Other Likely diagnoses:
- Diverticulitis: Although the CT scan does not show evidence of diverticulitis, the presence of scattered diverticula of the rectosigmoid colon increases the risk of developing diverticulitis.
- Adhesions or bowel obstruction: The CT scan shows anastomotic changes in the bowel in the left lower quadrant, which could be a sign of adhesions or bowel obstruction.
- Fatty liver disease: The CT scan shows diffuse fatty change of the liver, which could be a sign of fatty liver disease.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
- Ovarian torsion: Although the CT scan does not show evidence of ovarian torsion, it is a life-threatening condition that requires prompt diagnosis and treatment.
- Ectopic pregnancy: Although the CT scan does not show evidence of ectopic pregnancy, it is a life-threatening condition that requires prompt diagnosis and treatment.
- Appendicitis: Although the CT scan does not show evidence of appendicitis, it is a life-threatening condition that requires prompt diagnosis and treatment.
- Rare diagnoses:
- Ovarian cancer: Although the CT scan shows a cyst-like lesion in the left adnexa, the possibility of ovarian cancer cannot be entirely ruled out.
- Endometriosis: The CT scan shows a right paramidline uterus, which could be a sign of endometriosis.
- Inflammatory bowel disease: The CT scan shows anastomotic changes in the bowel in the left lower quadrant, which could be a sign of inflammatory bowel disease.
