Inflammatory myofibroblastic tumor in the intradural extramedullary space of the lumbar spine with spondylolisthesis: case report and review of the literature

Abstract

An inflammatory myofibroblastic tumor (IMT) is a rare disease entity reported to arise in various organs but still thought to be a neoplastic or reactive inflammatory condition controversially. The author reports an extremely rare case of intradural extramedullary IMT of lumbar spine which was presenting radiculopathy and neurogenic intermittent claudication due to concomitant spondylolisthesis.

Intradural Extramedullary Spinal Inflammatory Myofibroblastic Tumor: Case Report and Literature Review

“…MRI features of intradural extramedullary IMT were poorly documented in four [3,6,9,11] of the nine cases reported. In the present case, MRI showed a mass that was isointense on T1-weighted sequences and hypointense on T2-weighted sequences.…”

“…To the best of our knowledge, since the first description by Eimoto et al [5], only nine cases of intradural extramedullary [3][4][5][6][7][8][9][10][11] tumors have been reported in the literature (Table 1). A few other cases of epidural [14][15][16][17] or intramedullary [18][19][20] spinal IMT have been reported.…”

“…Spinal meningeal involvement is rare. To the best of our knowledge, only nine cases of intradural extramedullary spinal lesions [3][4][5][6][7][8][9][10][11] have been reported in the literature. We report the case of an intradural extramedullary IMT of the cervical spine in a 43-year-old male.…”

An inflammatory pseudotumor in the thoracic epidural space presenting with progressive paraplegia: a histopathological diagnosis with clinical and radiological uncertainty. Case report with literature review

“…Our patient presented with IPT at upper thoracic level and was associated with hypothyroidism, but FNAC of the thyroid mass has not proven any inflammatory pathology, so it was considered co-incidental. Few cases of intra-dural IPTs have also been reported [15][16][17][18][19][20][21][22][23][24].…”

Intraosseous Inflammatory Myofibroblastic Tumor of the Twelfth Thoracic Vertebra

“…Their occurrence has been reported in cranial bones [10][11][12] , long bones 13,14 , the sacrum 9 , and the iliac bone 15 . IMTs in the spinal system are also reported [16][17][18][19] , but primary occurrence in a vertebral body is extremely rare 1 . Roberts et al described a case of an IMT of the T10 vertebra compressing the thecal sac and involving the paravertebral muscles 20 , but it was unclear whether the IMT originated from the vertebral bone or from the surrounding soft tissues.…”
