Persistent pain is common following thoracotomy. A 64-year-old retired electrician with Type 2 diabetes presented with chest wall and abdominal pain 3 months following video-assisted thoracoscopic surgery (VATS). Postoperatively the patient had suffered pain despite a functioning thoracic epidural catheter. Following investigation, his persistent pain was due to diabetic thoracic radiculopathy (DTR). The disorder is characterized by pain, sensory loss, abdominal and thoracic muscle weakness in patients with diabetes. As in this patient, the pain and sensory loss usually resolve within one year after onset. The disorder may be distinguished from intercostal neuralgia based upon clinical and electromyographic features.

Herpes zoster (HZ) is essentially a viral disease of the posterior root ganglia and sensory nerve fibers, which presents clinically with vesicular eruption of the skin, radicular pain and sensory changes in the distribution of the affected ganglion. However, motor involvement can be seen as well. If classic cutaneous lesions are present, HZ-related motor paresis is easily diagnosed. Otherwise, the diagnosis may be suspicious, especially if the weakness occurs before the cutaneous lesions have appeared, or weeks after they have subsided. We present a patient with HZ-related motor paresis due to radiculopathy in the cervical segments whose motor symptoms and signs appear as major clinical features.

Although soft tissue calcifications are well known to occur as a late manifestation in scleroderma, symptomatic paraspinal calcinosis is very rare. Clinically, patients present with focal neck pain, weakness or radiculopathy, and decreased range of motion of the neck. We describe the imaging features of a rare case of cervical paraspinal calcinosis in a 74-year-old woman with long-standing scleroderma. Standard radiography is usually sufficient to confirm the diagnosis, but CT-scan allows a more precise location of the calcifications around the facet joints, sometimes with associated erosions. The advantage of MRI is to evaluate the possible intraspinal extension of the calcifications in case of focal neurological symptomatology.

Patients with lower back or buttock pain that radiates into the posterior or lateral leg are often referred to physical therapy with a diagnosis of sciatica. Often the physical exam does not reveal neurologic findings indicative of radiculopathy. Instead, there is hip abductor muscle pain and weakness. This syndrome involves muscle imbalances that result in overuse strain of the gluteus medius and gluteus minimus muscles, myofascial trigger points, and trochanteric bursitis. This paper describes hip abductor pain syndrome and provides a rationale for the diagnosis and treatment.

Cervical dystonia (CD) is the most common form of dystonia encountered in a movement disorders clinic. The treatment of this focal dystonia has improved markedly with the advent on botulinum toxin (BTX) injections, which has now become the treatment of choice. Initial studies, even double-blind controlled trials, failed to show robust effect, largely as a result of poor design, often using fixed dosage and site of administration. When the BTX treatment is customized to the needs of the individual patients and the most involved muscles are targeted, the effects can be quite dramatic and the improvement usually lasts 3 to 4 months. Experience and improved skills can largely prevent the adverse effects such as dysphagia and neck weakness. Although there is no evidence that BTX slows the progression of the disease, as a result of early intervention with BTX, many of the long-term complications of CD, such as contractures and radiculopathy, have been largely eliminated.

Over a period of 25 years, a surgical technique has evolved for removal of a soft disc herniation in patients with sciatica and lumbar stenosis demonstrated on neuroradiological studies. Initially emphasis was placed on decompression of the entire narrow spinal canal when there was evidence of single nerve root involvement and no history of neurogenic claudication. The author has performed 12 microsurgical discectomies since 1984 and eight percutaneous endoscopic discectomies over the past 6 years that have been successful in relieving radiculitis and radiculopathy in cases of a single herniated nucleus pulposus, even in the presence of a stenotic canal. No patient complained of generalized numbness, weakness, or pain in the lower extremities while walking. After at least 1 year of follow up, the 20 patients who underwent microsurgical or arthroscopic procedures limited to removing the ruptured disc have not required more extensive decompression.

The authors report the case of a rare manifestation by vertebral artery dissection. A 15-year-old boy who presented with left shoulder weakness and numbness of the left arm was admitted to our hospital. Neurological examination on admission revealed muscle weakness of the left deltoid muscle and sensory disturbance of the left C5 area. MRI/MRA and 3D-CT angiography demonstrated an aneurysm-like dilatation of the left vertebral artery mainly at the C4/5 level. Partial thrombosis was noted in the dilated artery. The left vertebral angiogram showed that the second and third portions of the left vertebral artery had a dilated pseudo-lumen due to arterial dissection. The pseudo-lumen of the dissected vertebral artery was largest in diameter at the C4/5 level. The patient successfully underwent proximal occlusion of the dissected vertebral artery using detachable balloon and Guglielmi detachable coils. Proximal vertebral artery occlusion using an intravascular technique was regarded as a non-invasive and effective option for patients with a cervical radiculopathy due to cervical vertebral artery dissection.

The common diagnoses of cervical radiculopathy and upper-extremity entrapment neuropathies can at times be difficult to differentiate. Additionally, thoracic outlet syndrome is often diagnosed when, in fact, the problem is radiculopathy or neuropathy. Another source of confusion, especially in older patients, is neuralgic amyotrophy, brachial plexitis, or the Parsonage-Turner syndrome. The differential diagnosis of unilateral arm pain, weakness, and/or sensory loss includes all of these problems. The clinical and electrodiagnostic features of each are discussed as an aid to distinguishing between these common and similar entities.

This retrospective study aims to discuss and compare our results with those previously mentioned in the literature with regard to C5-C6 radiculopathy that occurs after decompression carried out for cervical spondylotic myelopathy. There are few reports in the literature referring to the incidence of the C5-C6 radiculopathy following cervical decompression procedures. Some authors believe that the postoperative cord shift is the most likely cause. From January 1994 to November 2002, 121 patients underwent cervical corpectomies for cervical spondylotic myelopathy. The preoperative and the postoperatively discovered paresis have been assessed according to the criteria of the British Medical Council. The Nurick Scale was used to grade the severity of the myelopathic changes. The follow-up period varied from 4 to 111 months with an average of 50 months. Symptoms of C5 and/or C6 radiculopathy appeared in 10 patients (8.2%) postoperatively. Aggravation of a preoperative C5 and/or C6 radiculopathy was seen in 3 patients, while 7 patients developed a new C5 and/or C6 radiculopathy in the immediate postoperative period. These motor deficits resolved completely in 7 patients within 7 months of surgery, whereas a residual motor weakness remained in the other 3 patients. The postoperative C5 motor deficit is not infrequently associated with partial involvement of the C6 root. The lesions can be either unilateral or bilateral with a statistically average frequency of 8%. The prognosis is generally favorable. Our results did not support the hypothesis that the claimed cord shift phenomenon is a possible aetiology.

We report the development of a malignant peripheral nerve sheath tumor (MPNST) in 2 patients after irradiation for Hodgkin's lymphoma. Clinicians should be aware of this uncommon, but important fatal complication of radiation therapy. The first case is a 37-year-old man who was diagnosed with nodular sclerosing (NS) Hodgkin's lymphoma and underwent successful mantle radiation. He presented to our neurosurgery service with a left C6 radiculopathy 6 years later. The second case is a 30-year-old female diagnosed with NS Hodgkin's lymphoma. She did well with extensive radiotherapy until 5 years later when she developed severe right arm and chest pain secondary to recurrent lymphoma. After aggressive radio- and chemotherapy, she presented to the neurosurgery service with a right Horner's syndrome, right C6 radiculopathy, and weakness of her right triceps and wrist extensors. Both patients obtained magnetic resonance imaging revealing intradural extramedullary cervical nerve root associated mass lesions. Two years after radiation therapy for his Hodgkin's lymphoma, the first patient underwent a C6 laminectomy at an outside institution for resection of a benign neurofibroma. Four years later, he underwent a posterior C5-7 laminectomy with lateral mass plate fusion and partial excision of a recurrent mass diagnosed as a MPNST. The second patient underwent a C5-6 hemilaminectomy and partial resection of a tumor also pathologically consistent with MPNST. We present 2 case reports of patients who developed neurofibrosarcomatous tumors with malignant transformation after undergoing radiation therapy for Hodgkin's lymphoma. Despite prompt surgical resection, these tumors exhibited aggressive behavior. Numerous cases of soft tissue tumors have been described to arise in areas of prior radiation therapy; however, there have been rare reports of de novo MPNST after radiation therapy, especially in the setting of Hodgkin's lymphoma. Postirradiation MPNST should be considered in the differential diagnosis of a painful, enlarging mass in a previously irradiated area.
