Supra-clavicular lymph node metastatic spread in patients with ovarian cancer disclosed at (18)F-FDG-PET/CT: an unusual finding
Tumoral dissemination of ovarian cancer most commonly occurs through the intra-peritoneal route; nevertheless, although it is rare, ovarian cancer may also metastasise through the lymphatic channels.

Sumario: | Tumoral dissemination of ovarian cancer most commonly occurs through the intra-peritoneal route; nevertheless, although it is rare, ovarian cancer may also metastasise through the lymphatic channels. Lymphatic diffusion of ovarian cancer usually involves pelvic and retro-peritoneal lymph nodes. Extra-abdominal lymph nodes are rarely involved and their detection may represent a challenge for the oncologist. We describe here two patients studied for ovarian cancer by [(18)F]fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT): one case during pre-operative staging, the other for restaging after surgery. In both cases PET examination identified extra-abdominal lymph node tumoral spread in the left supra-clavicular space; biopsy led to a final diagnosis of recurrent ovarian cancer. Previous reports in the literature on tumoral spread of ovarian cancer to the supra-clavicular nodes are rare, however this possible site of metastatic involvement has to be kept in mind by oncologists and our data show that the (18)F-FDG PET/CT may be useful to disclose this unusual supra-diaphragmatic lymphatic diffusion of metastatic lymphatic ovarian cancer. |
