 There are postoperative findings related to T3-T4 laminotomy/hemilaminectomy for fenestration of a dorsal cyst. There is a 12 x 24 mm well defined fluid collection within the epidural space in the surgical bed at the level of T3. There is a grossly unchanged loculated cystic lesion dorsal to the spinal cord extending from the T3-T8 levels. This lesion is somewhat heterogeneous although mainly follows CSF on all pulse sequences. It results in ventral displacement of the spinal cord and also widens the left neural foramina at the C4-C7 levels and the right neural foramen at the T4-T8 levels. There is unchanged thin enhancement of some of the septa. The spinal cord displays normal signal and morphology. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis.There are small bilateral pleural effusions. There are multiple hepatic masses as well as a left pulmonary nodule that are not well assessed on this exam.
1.Postoperative findings related to T3-T4 laminotomy/hemilaminectomy for fenestration of a dorsal cyst that appears essentially unchanged with ventral displacement of the spinal cord. 2.No cord signal abnormality. 3.12 x 24 mm fluid collection within the epidural space at the level of T3 may represent seroma or CSF.4.Small bilateral pleural effusions.5.Multiple hepatic and pulmonary metastases that were better assessed on the prior CT.
