BACKGROUND AND PURPOSE Peripheral nerve disorders caused by benign and malignant primary nerve sheath tumors, infiltration or compression of nerves by metastatic disease, and postradiation neuritis demonstrate overlapping features on conventional MR imaging but require vastly different therapeutic approaches. We characterize and compare diffusivities of peripheral nerve lesions in patients unde...

Endometriosis is a common disease characterized by the presence of endometrial tissue outside the uterus, such as over, colon, nasal mucosa. Furthermore, it can affect sciatic nerve as a rare presentation causing cyclic sciatica, chronic pelvic pain, paresis, and paresthesia. Early diagnosis and treatment is very important to minimize the nerve damage caused by endometrial focus on sciatic nerv...

A 26 year old, healthy, 41 week primiparous woman received a patient-controlled epidural analgesia (PCEA) and experienced paraplegia 11 hours later after a vaginal delivery. This was thought to be the result of complications from PCEA but there was no specific abnormality on magnetic resonance imaging (MRI) of the lumbosacral spine. On an electromyography (EMG) study performed 15 days following...

Atypical sciatica and discrepancy between clinical presentation and imaging findings is a dilemma for treating surgeon in management of lumbar disc herniation. It also constitutes ground for failed back surgery and potential litigations thereof. Furcal nerve (Furcal = forked) is an independent nerve with its own ventral and dorsal branches (rootlets) and forms a link nerve that connects lumbar ...

Patients undergoing total hip and knee arthroplasty experience substantial and sustained postoperative pain. Inadequate analgesia may impede recovery and delay hospital discharge. Traditionally, postoperative analgesia following arthroplasty was provided by intravenous patient-controlled analgesia or epidural analgesia, but each technique has distinct advantages and disadvantages. Recently, per...

Neurolymphomatosis, defined as invasion of cranial nerves and peripheral nerve roots, plexus or nerves by Non Hodgkin’s Lymphoma is a very rare clinical entity. We describe a case of 69 years old gentleman, who presented to us with asymmetric, painful sensorimotor polyneuropathy. He was admitted with 2 months history of dry cough, constitutional symptoms, paraesthesias on right side of face alo...

Resection of retroperitoneal tumors is usually performed using the anterior retroperitoneal approach. Our report presents an innovative method utilizing a robotic surgical system. A 50-yr-old male patient visited our hospital due to a known paravertebral mass. Magnetic resonance imaging showed a well-encapsulated mass slightly abutting the abdominal aorta and left psoas muscle at the L4-L5 leve...

Lumbosacral Transitional Vertebrae (LSTV) is the rare medical term used to describe congenital or acquired of lumbosacral vertebral junction abnormalities associated with without pain at lower back (Almeida, et al. [1]).

The main symptom of pressure on nerves is paraesthesia. Depending on the level of the compression, paraesthesia is accompanied by pain and numbness. The combination of these three symptoms and their interrelation are of importance in localizing the site of compression. Pressure on the distal spinal cord induces painless pins and needles in both feet, soon followed by numbness, incoordination an...
