“…Thus, neural enhancement with Gd-DTPA is only a visual MR parameter of BNB disruption and is not necessarily a prerequisite for pathophysiological changes linked with clinical signs and symptoms. BNB disruption and radicular pain are two fundamentally different pathophysiological processes that may or not be associated both temporally and spatially [19].…”

The aim of our study was to evaluate the contrast-enhanced MR imaging (MRI) findings, in the early postoperative period, in unselected patients undergoing lumbar microdiscectomy (15/16 had total resolution of their symptoms). Contrast-enhanced imaging studies were performed, in all 16 patients of our series, before surgery, and at the third postoperative day and, two months after surgery. Postoperative paraspinal muscles enhancement was present in all patients. In the postoperative period, nerve root enhancement was present in 5/16 patients at the early survey and persisted in one after two months. A pseudohernia depicted as epidural intermediate signal intensity tissue, was seen in 13 patients at the third day MRI, and only in eight after two months. This pseudohernia enhanced peripherally in 8/13 patients and enhanced homogeneously in the remaining five at the first postsurgical examination; in the late MRI the peripheral enhancement was appreciable in only two patients while a homogeneous enhancement was observed in six. Clinical symptoms resolved completely in 14/16 patients on clinical evaluation at the third postoperative day, while the remaining two patients showed residual symptoms and signs of radicular compression. At the early MRI these two patients showed intradural nerve root enhancement. Two months later, one patient did not show the previously described nerve root enhancement and improved clinically, while the other had a positive Straight Leg Raising Sign with persistent intradural nerve root enhancement. In conclusion, no correlation between clinical course and contrast-enhancement of pseudohernia and extradural nerve root was appreciable, although intradural nerve root enhancement seems to represent a clinically relevant finding.

“…MRI can discover residual spinal stenosis, facet joint pathologies, and synovial cysts. Neural MRI imaging has been shown to be the most sensitive test for evaluating neural compression in FBSS patients [72] . Although extradural compression can be recognized with myelography or CT, they can't differentiate disc hernia and epidural scar tissue formation [60] .…”

Failed Back Surgery: A Clinical Review

Failed back surgery syndrome (FBSS, failed back syndrome) is a chronic disorder that has many impacts on the patients and health care systems. The predisposing factors may occur in the preoperative, intraoperative, and postoperative periods. The term FBSS is often misused. It is not actually a syndrome, but is a very generalized term that is often used to describe the condition of patients who had unsuccessful results with back surgery or spine surgery, or experienced continued pain after surgery. Patients describe uncontrolled persistent back, back/leg or leg pain with functional insufficiency with or without sciatica after 10-40% of the all spinal surgeries. Literature about the FBSS is insufficient, due to the complexity of this entity with variety of the underlying etiology and lack of high-quality clinical trials determining response to treatment modalities. This review aims to summarize current concepts in the ligthnings of literature findings.
