Splenoid cyst is growing

[robertb]

Hello! About 3 years ago, I had a CT scan (they were looking for a kidney stone), but "accidentally" found a cyst on my spleen a little smaller than 1 cm. An MRI was scheduled which confirmed it was just a fluid filled cyst.

I had another CT yesterday thinking I had another stone. That 1 cm cyst is now 4 cm. I will have another appt with my primary this week to discuss it, but I was wondering what do you think this could be and is the growth significant and what (if any) actions do you think my doctor would (or should) recommend?

Also, I am "borderline" diabetic (even though I know there's really no such thing) but lately my bg levels are running up some. Whereas my fasting used to be around 80, it's now 140 and my (2 hour after meals) reading is running around or above 200. Can a splenoid cyst affect the pancreas and thereby affect insulin/glucose levels?

Thank you,
Robert

Hello,

The most common cause of splenic cyst is posttraumatic cysts. Misdiagnosed traumas to the spleen result in intrasplenic hematoma or laceration that is seen by scan as cysts. Difficult colonoscopy for example has been reported to cause splenic trauma and hematomoas.

Other cysts that are not uncommon include inflmmatory spelnic abcess and pancreat pseudocysts. Whether these cysts affected the pancreatic function and insulin release or not is uncertain and is difficult to tell.
These cysts rarely become malignant.

Neoplastic cysts in the spleen are not common and include cavernous hemangioma (benign), lymphoma, angiosarcoma and metastases (malignant).

Management depends on the nature of this mass and its effect.

I would advise you to follow up with your physician.
