Question asked:

i have stage 3 testicular cancer. embryonal carcinoma. normal afp hcg ldh elevated. on ct there are retroperitoneal mets and lung mets and also a single hypodense lesion 10*9 mm on my liver. the ct was a contrast ct and it says that the lesion is of unknown genesis. the follow up ultrasound says it is a hyperechoic lesion of an irregular shape with clear contour. and the us doc says that it is a hemangioma. what is it most likely

I appreciate you sharing your detailed imaging findings. Let me be direct about what I can and can't tell you here.

What the imaging likely means (educational context):

The retroperitoneal and lung mets are consistent with stage 3 testicular cancer spread. Your elevated tumor markers (normal AFP, elevated HCG and LDH) align with embryonal carcinoma biology.

The liver lesion is the tricky one. Here's what you have:

CT says: "unknown origin" (10×9 mm hypodense lesion)
Ultrasound says: hyperechoic, irregular shape = "hemangioma"

These descriptions actually don't match well. A hemangioma typically looks the same on both CT and ultrasound. The fact that it looks different on each imaging study is a red flag that it might be something else.

Possibilities (in order of likelihood given your cancer):

Metastatic lesion from your testicular cancer (most concerning)
Hemangioma (benign blood vessel tumor - what the ultrasound suggested)
Other benign lesion (cyst, focal fat, etc.)

What you actually need:

This lesion needs definitive characterization before your treatment plan. Standard next steps would be:

MRI of the liver (best for characterizing small lesions)
PET-CT (would light up if it's cancer; won't if it's benign)
Possible biopsy if imaging remains unclear

The critical question:

Does this change your treatment? If it's metastatic disease, you're still stage 3 and the standard approach is chemotherapy (BEP or EP regimen per NCCN Guidelines for testicular cancer). If it's benign, it doesn't change anything.

Questions for your oncologist:

"Does this lesion change my stage or treatment plan?"
"Can we get an MRI or PET-CT to clarify what this is?"
"If it's benign, do we monitor it or ignore it during treatment?"
"What's your recommendation—biopsy or imaging follow-up?"

This information is for educational purposes only. Always consult your healthcare team for personalized medical advice and decisions.

Your oncology team needs to resolve this before starting treatment. Don't move forward until you have clarity on this lesion.
