“…Primarily, it allows a diagnostic orientation of the tumor, and, secondly, it shows anatomical relationships between the tumor and the neurovascular structures. Classically, lipomas appear as a homogeneous mass, with a sharp border, spontaneous T1 and T2 hypersignals, reduced signal intensity after erasure of the fat signal, and no raising in the signal using the gadolinium contrast agent [12,13]. Fine cuts, smaller than 2 mm, allow identification of septae inside the tumor, which appear as small, discreetly raised features after gadolinium injection [12].…”

A lipoma is a common, benign soft-tissue tumor that rarely arises in the upper limb. When one does occur in the hand, the location of the lipoma can cause nerve compression, which can mimic carpal tunnel symptoms. Magnetic resonance imaging is the visualization modality of choice for diagnosis and surgical planning of lipomas. Surgical resection is recommended to relieve the neurological manifestations of this disease. The surgeon should always suspect liposarcoma first before voluminous, atypical, or recurrent tumors are considered.

“…The ganglion cyst, which is composed of mucoid material surrounded by fibrous tissue, is the most frequently encountered soft-tissue mass of the hand 51 . Although most ganglion cysts are diagnosed clinically, MRI may help detect occult ganglia that cause chronic dorsal wrist pain 1 and distinguish these from focal synovitis or other pathologic processes.…”

“…The peripheral fibrovascular rim signal, on the other hand, is hyperintense on the T 1 weighted and hypointense on the T 2 weighted images when compared with the signal of the abscess content. Inflammatory changes are present around the abscess, and peripheral contrast enhancement is typically observed following intravenous contrast administration ( Figure 7) [5].…”

ABSTRACT. Sciatica is the most frequently encountered symptom in neurosurgical practice and is observed in 40% of adults at some point in their lives. It is described as pain of the hip and the lower extremity secondary to pathologies affecting the sciatic nerve within its intraspinal or extraspinal course. The most frequent cause is a herniating lumbar disc pressing on the neural roots. Extraspinal causes of sciatic pain are usually overlooked because they are extremely rare and due to intraspinal causes (lumbar spinal stenosis, facet joint osteoarthritis, fracture, and tumors of the spinal cord and spinal column) being the main consideration. Early diagnosis of sciatica significantly improves the likelihood of relieving symptoms, as well as avoiding any additional neurologic injury and unnecessary surgery. We evaluate histolopathologically confirmed extraspinal causes of sciatica cases, accompanied by their presented computed tomography and/or magnetic resonance imaging findings. AnatomyBeing familiar with the anatomy of the lumbosacral plexus and sciatic nerve is essential for the evaluation of extraspinal sciatica. The lumbar plexus is composed of the ventral rami of L1-L4 and is anatomically located behind the psoas muscle. A minor branch of L4 combines with the ventral ramus of L5 to form the lumbosacral cord or trunk. The lumbosacral trunk descends over the sacral ala and combines with the ventral rami of S1, S2 and S3 (and a branch of S4) to form the sacral plexus [1].
