Peritoneal tuberculosis with benign ovarian tumor

Rectal cancer combined with abdominal tuberculosis: A case report

BACKGROUND

It is very rare to suffer from colorectal adenocarcinoma and abdominal tuberculosis simultaneously. Even in a country such as China, where tuberculosis is still endemic, its diagnosis and treatment are challenging. This article describes in detail a case of rectal cancer complicated by abdominal tuberculosis and its pathological features.

CASE SUMMARY

We outline the case of a 71-year-old female who was admitted with intermittent blood in the stool over the past year. The patient was diagnosed with low rectal cancer and received neoadjuvant therapy. The patient then returned to the hospital for surgery, but diffusely distributed nodules were found during laparoscopic exploration. The diagnosis of rectal cancer with extensive metastasis was considered during the operation. There was no opportunity for radical surgery. Thus, nodules were taken for pathological examination, and the abdomen was closed. The histopathological diagnosis was tuberculous granuloma, and the patient was treated with standardized anti-tuberculosis drugs in a specialized hospital. Later, the patient again came to our hospital and underwent abdominoperineal resection. She was discharged 10 d after the operation in good clinical condition.

CONCLUSION

We aim to emphasize the importance of preoperative and postoperative pathological examination in diagnosis and treatment.

Peritoneal thickening: It's not always carcinomatosis

The peritoneal pseudotumor localization of tuberculosis is a rare clinical form, representing 1 to 3% of extrapulmonary site of tuberculosis. It represents the sixth most common extra pulmonary site of tuberculosis. It is a great mimicker with major overlapping clinical and imaging features. Differentiating peritoneal tuberculosis and peritoneal carcinomatosis in imaging remains challenging. We present a case of a 37-year old woman complaining of chronic abdominal pain and distension who has been diagnosed to have peritoneal carcinomatosis based on CT findings, histopathological study then revealed necrotizing, granulomatous inflammation consistent with tuberculosis. This case showed the interest to be aware of the common and uncommon imaging features of tuberculosis by radiologists to better assess for alternative differential diagnosis.
