Abstract
Spontaneous Regression of a Large Symptomatic Calcified Central Thoracic Disc Herniation: A Case Report with a Review of the Literature
Highlights
The thoracic spine is the least common region to present with a disc herniation in comparison to cervical and lumbar regions
Males are more commonly affected than females, and surgery is the treatment of choice for large symptomatic calcified central thoracic disc herniation (TDH) [6]
We have reported a case of a large central calcified TDH that has spontaneously regressed over four and half months while the patient was waiting for surgical decompressive surgery
Summary
Disc herniations in the thoracic spine are rare and the incidence of symptomatic thoracic disc herniation (TDH) is 1 in a million. The incidence of asymptomatic TDH varies from 11-13%. They are classified as small (≤10%), medium (11-20%), large (21-40%), or giant (≥41%) based on the extent of canal compromise on advanced imaging. The large symptomatic calcified central TDHs are best treated operatively, as the disc fragment could be adherent to the dura or remain intra-dural [1]. The relevant MRI and CT scan images with a review of the salient literature are discussed. We believe this to be the first such case of a spontaneous regression of a large symptomatic central calcified TDH to be reported in English literature that is documented with CT and MRI scans
