Carcinoma lung with intra-spinal metastases - PET/CT.

PET/CT fused image of a 65 year old smoker showing large intensely FDG avid mass lesion in the left upper lobe with areas of necrosis and mediastinal FDG avid lymphadenopathy.

Sagittal PET/CT fused whole spine image showing intraspinal intense FDG avid focal lesions at C7-D1 and L1 levels suggestive of metastases.

Sagittal PET/CT fused cervical spine image showing intraspinal intense FDG avid focal lesion.

Axial PET/CT fused cervical spine image at C7 level showing intraspinal intense FDG avid focal lesion.

Axial PET/CT fused cervical spine image at L1 level showing intraspinal intense FDG avid focal lesion

Discussion:

The intraspinal metastases may spread through several routes, such as arterial dissemination; venous spread through the network of communicating venous channels in the spinal cord and the cauda equina; spread via the perineural lymphatic vessels or the subarachnoid space; invasion of a dorsal root; or direct extension of the primary tumor.
Lung carcinoma commonly metastasize by arterial dissemination.

Four UCLA departments — urology, radiology, pathology and biomedical engineering — collaborated with the medical device company Eigen Inc. to develop and test the technology. The team's early experiences with it are reported in the online May–June issue of Urologic Oncology. http://mriscan.blogspot.com
