Infrabladder "cup defect" following prostatectomy: recognition on bone scintigram

Area of Science:

• Nuclear medicine imaging
• Urologic oncology

Background:

• Prostatectomy is a common procedure for prostate cancer.
• Bone scintigraphy is used to detect bone metastases.

Purpose of the Study:

• To describe a specific finding on bone scintigraphy after prostatectomy.
• To investigate the cause and significance of the

• Conclusions

Main Methods:

• Retrospective review of 17 bone scintigrams.
• Analysis of imaging findings before and after prostatectomy.

Main Results:

• A "cup defect" below the bladder was observed in 17 patients post-prostatectomy.
• This finding correlated with the extent of tissue removed during transurethral prostatectomy.
• In 2 cases, the defect appeared only after surgery.

Conclusions:

• The "cup defect" is a potential imaging finding after prostatectomy.
• It is likely related to surgical technique and tissue volume.
• Differential diagnosis and persistence of the finding warrant further consideration.
