Spinal Cord Diseases

MRI is currently the standard imaging modality for spinal tumors as it delineates the accurate spinal anatomy and classifies it as being an intra/extramedullary and intradural/extradural in location, the extent of involvement and associated findings like cord edema/ syringomyelia which aid to establish a preliminary preoperative diagnosis for further surgical management. Since the abnormalities seen on PET/MRI may sometimes be less extensive than the abnormalities seen on MRI, PET and MRI may synergistically demonstrate discretely the most metabolically active part of the tumor, edema and other cord changes being non-avid. Since residual intramedullary tumors of the spinal cord are not always easily distinguished from radionecrosis, PET/MRI could add useful information in the assessment of residual/recurrent disease post-treatment.

 

Craniospinal TB Case

---

Case History:

63 year old female, Follow up case of craniospinal TB.

---

Findings:

 

Sagittal post-contrast VIBE (A, B) reveal enhancing intramedullary and leptomeningeal deposits all along the cord with increased FDG uptake seen on the PET MIP image ( C).

 

There is a complete regression of the intramedullary and leptomeningeal deposits (D, E) along the cord with complete regression of FDG uptake. (F)
