Patient's Query

Hello doctor,

There was something found on top of the intestine that measured 17 x 4 cm. We would like to receive a diagnosis from your doctors. We have attached the reports for your reference. We have known about this diagnosis for about four days. The patient experienced pain in his back, so he went to the hospital. They told him that he has very, very small kidney stones that have passed successfully.

But, at the same time, they found this 17 x 4 cm mass on top of his intestine. So, they told him to perform a CT scan. Appendectomy was performed in 1985. He is currently on Aspirin. Please help.


Welcome to icliniq.com.

I evaluated your CT (computed tomography) images (attachment removed to protect patient identity) and found this thin-walled cystic lesion in the right iliac fossa with curvilinear as well as chunky wall calcification arising likely from the ileocecal junction.

Probable cause could be postoperative changes and complications.

Differential diagnoses include mucocele from an appendicular stump and mucinous cystadenoma of the appendicular stump.

It is elevating the right kidney and indenting the right psoas muscle; however, the fat planes appear well preserved.

Above findings indicate a benign process more likely than a malignant one.

I would require the coronal and sagittal plane images for localization of the lesion and then only I can provide the possible diagnosis.

This professional advice provided by me stands subject to the actual examination of report and image and is based entirely on inputs provided to me. It should be correlated with clinical findings.
