Abstract
Longitudinally extensive transverse myelitis (LETM) is an unusual manifestation of
systemic malignancy. It has been mainly reported with lung cancers and lymphoproliferative
malignancy. LETM in systemic malignancy can be caused by either intramedullary metastases
or paraneoplastic syndrome. Occurrence of LETM as the first manifestation of malignancy
has been rarely reported. We present clinical, laboratory, and imaging findings of
a 66-year-old man with nonsmall-cell lung (adeno) carcinoma, who presented with LETM
without having any cardinal manifestations of lung malignancy. The rarity of the disease
and especially such a presentation can cause considerable delay in the diagnosis and
treatment.
