congenital  

SInce birth, there was a 3.x3 cm, indolent swelling in the back with slight increase in size. Localized dorsally in the thoracic vertebral area between the shoulder blades. Otherwise, the child is unremarkable.  

In a hibernoma, the tumor is composed of brown fatty tissue, which is known in the animal-world as the hibernation gland. Brown fatty tissue is known to be located in the back area, around the kidneys and around the aorta in a baby.

MRI 1: T1-weighted image, sagittal: about 3.5 x 1 x 3 cm hyperintense tumorous mass in the subcutaneous fatty tissue.






<- view MRI 2

MRI 2: T1-weighted image; transversal: about 3.5 x 1 x 3 cm hyperintense tumorous mass in the subcutaneous fatty tissue.

Also in the T2-weighted image (no image): hyperintense. Due to the T2-weighted TSE sequence, no proof of liquid components (no image). No proof of a tethered cord.

Lipoma, lipomatous tumor in a meningocele  

Rare, benign tumor with tendency for growth.
Often, the hibernoma is asymptomatic. Treatment: Surgical resection is suggested, although no tendency for malignancy has been noted. In complete resection no regression has been described.
