Port-Site Metastasis After Laparoscopic Removal of an Isolated Adrenal Metastasis in a Patient With Breast Cancer Detected With FDG PET/CT

Abstract

Adrenal metastasis from breast cancer rarely occurs in the course of this disease. Laparoscopic surgery has increased in the therapy for malignant tumors because of its lower morbidity and mortality compared with conventional surgical methods. However, complications such as the appearance of a port-site metastasis may also occur. Clinical examination and conventional cross-sectional imaging usually reveal this only at advanced stage. The authors reported on a case with abdominal wall port-site metastasis detected with F-FDG PET/CT 33 months after the laparoscopic removal of a late-onset, PET/CT-verified adrenal metastasis from lobular breast cancer.

Left adrenal gland metastasis of breast invasive ductal carcinoma: A case report

“…many advantages, including reduced requirement of analgesia following surgery and the patient being discharged earlier (11). However, while performing LA to resect primary carcinoma or metastasis of the adrenal gland, carcinomatosis and port-site metastasis, which may be caused by several factors, including the behavior of the tumor, patient's condition and the operation of surgery, should be taken into consideration as they have been reported previously (12). It is also important to avoid port-site metastasis and carcinomatosis when performing LA.…”

Late Port Site Metastasis from Occult Gall Bladder Carcinoma After Laparoscopic Cholecystectomy for Cholelithiasis: The Role of 18F-FDG PET/CT

“…Very rarely, the primary GBC may remain occult even at histopathology and present later as port site metastasis [3,4]. Functional imaging with 18 F-flurodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) has been employed for diagnosis of port site metastasis after laparoscopic surgery [5,6]. We here present two cases of late port site recurrence from occult GBC after laparoscopic cholecystectomy for cholelithiasis and discuss the role of 18 F-FDG PET/CT in this setting.…”

FDG-PET/CT Manifestation of Tumor Seeding Along Percutaneous Biliary Drainage Catheter Tract

“…As in our case, the uncommon findings on FDG PET/CT can be a manifestation of iatrogenic tumor seeding along the procedure tract. [9][10][11][12] …”
