Muscle metastases from gallbladder cancer

Area of Science:

• Oncology
• Medical Imaging

Background:

• Gallbladder cancer is aggressive with a poor prognosis, often diagnosed at advanced stages.
• Common metastasis sites include lymph nodes, liver, and peritoneum.
• Rare metastatic sites like thyroid and breast have been documented.

Observation:

• A patient with a history of gallbladder cancer presented with persistent haemoptysis.
• FDG-PET/CT imaging was performed due to the persistent symptoms.
• The imaging revealed unsuspected metastases.

Findings:

• The patient exhibited unexpected muscle metastases.
• Pulmonary metastases were also detected concurrently.
• These findings were identified in a patient with a history of gallbladder cancer.

Implications:

• This case highlights the potential for gallbladder cancer to metastasize to muscle tissue.
• FDG-PET/CT is a valuable tool for detecting unusual metastatic spread.
• Understanding rare metastatic patterns is crucial for accurate diagnosis and patient management.
