Induration in the rectal pouch on a rectal examination in a 65-year-old woman with bilateral ovarian masses is an example of
**Core Concept**
Induration in the rectal pouch is a clinical finding that suggests the presence of a mass or a lesion in the rectum or the surrounding tissues. This finding is often associated with rectal cancer, but it can also be seen in other conditions such as rectal lymphoma or metastatic disease from other primary tumors.
**Why the Correct Answer is Right**
The presence of bilateral ovarian masses in a 65-year-old woman suggests the possibility of ovarian cancer. Ovarian cancer can metastasize to the rectum, leading to the formation of a mass or a lesion that can cause induration in the rectal pouch. The rectal examination findings are consistent with metastatic disease from ovarian cancer. The rectal pouch is a common site for metastatic deposits from ovarian cancer, and the presence of a mass or induration in this area is a significant finding that warrants further investigation.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not take into account the clinical findings of bilateral ovarian masses, which are a strong indicator of ovarian cancer.
**Option B:** This option is incorrect because it is too broad and does not specifically address the clinical scenario presented.
**Option C:** This option is incorrect because it does not provide a clear explanation for the presence of induration in the rectal pouch.
**Clinical Pearl / High-Yield Fact**
When performing a rectal examination, it is essential to be aware of the possibility of metastatic disease from ovarian cancer, particularly in postmenopausal women with bilateral ovarian masses. A mass or induration in the rectal pouch can be a significant finding that warrants further investigation, including imaging studies and biopsy.
**Correct Answer: D. Metastatic disease from ovarian cancer.
