Episacral Lipoma-Tumor (ELT)

Dear Readers
 I have found a very important article for you written by Z.  Oezeri , Turkish, because it clears the differences when people have problems of the low back, that it cause also from Episacral lipoma Tumor (ELT)  Here is the detail report:
Abstract:  Episacal lipoma is a small, render subcutaneous nodule primarily occurring over the posterior iliac crest. ELT is a significant and treatable cause of acute and chronic low back pain. ELT occurs as a result of tears in the thoracodorsal fascia and subsequent herniation of a portion of the underlying dorsal fat pad through the tear. This clinical entity is common, and recognition is simple. The presence of a painful nodule with disappearance of pain after injection with anaesthetic, is
diagnostic.

Medication and physical therapy may not be affective. Local injection of the nodule with a  solution of a anaesthetic and steroid is effective in treating the ELT. Here we describe 2 patients with painful nodules over the posterior iliac crest. One patient complained of severe lower back pain radiating to the left lower extremity and this patient subsequently underwent disc operation. The other patient had been treated for greater trochanteric pain syndrome. In both patients, symptoms appeared to be relieved by local injection of anesthetic and steroid. ELT should be considered during diagnostic workup  and in differential diagnosis of acute and chronic low back pain.
