Overview
The abdominal ultrasound scan may be helpful in the diagnosis of glucagonoma. Finding on ultrasound scan suggestive of glucagonoma is a hypoechoic tumor in the distal pancreas. US-guided fine-needle aspiration biopsy is a non-operative histologic diagnosis. Intraoperative ultrasonography is used as an adjunct to intraoperative palpation.
Ultrasound
The ultrasound findings associated with glucagonoma are:[1][2][3]
- Endoscopic ultrasonography can detect lesions as small as 2 mm.
- It is more sensitive than CT or transabdominal ultrasonography for detection of glucagonoma.
- US-guided fine-needle aspiration biopsy is a good non-operative way to histologically diagnose glucagonoma.
- Finding of a hypoechoic tumor in the distal pancreas on ultrasound is suggestive of glucagonoma.
- Intraoperative ultrasonography is used as an adjunct to intraoperative palpation.
