A gastric and pleural metastasis of occult breast lobular cancer in an elderly female and radiomics assisted analysis of a rare metastasis

Key Points

• Gastric metastasis from occult breast lobular cancer presents significant diagnostic challenges, complicating effective treatment planning.
• Analysis revealed that coordinated immunohistochemistry and CT-based texture analysis effectively assisted in characterizing lesions.
• Observational assessment highlighted the evolving nature of metastases, emphasizing the need for refined monitoring techniques in cancer care.
• This case underlines the potential for radiomics to improve diagnostic precision, but broader studies are required for validation.
