1/39. Cranio-facial and humeral melorrheostosis.First described by LERY and JOANNY in 1992, melorrheostosis is an uncommon linear hyperostosis of unknown aetiology, which may be associated with soft tissures changes. Although all bones may be affected, cranio-facial involvement is very rare. Only six such cases have been found in the literature. This report describes a case of cranio-facial and left humeral melorrheostosis with symptomatic radial nerve involvement. Resection of the melorrheostotic bone was performed because of involvement of the radial nerve.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
2/39. Aseptic meningitis caused by Teflon implantation for microvascular decompression. Case report.The authors present the case of a 47-year-old man who, after undergoing microvascular decompression for trigeminal neuralgia, experienced symptomatic pain relief but developed prolonged aseptic meningitis. This case is unusual in that the patient remained dependent on steroid medications for nearly 5 months following the initial surgery and the aseptic meningitis did not resolve until after surgical removal of the Teflon used to pad the trigeminal nerve. The pathophysiological characteristics of the body's reaction to implanted Teflon are discussed along with the rationale for removing this substance in cases of prolonged intractable aseptic meningitis.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
3/39. Adhesive arachnoiditis causing cauda equina syndrome in ankylosing spondylitis: CT and MRI demonstration of dural calcification and a dorsal dural diverticulum.We present the radiological features of a 42-year-old man with long-standing inactive ankylosing spondylitis (AS), demonstrating that arachnoiditis is a cause of a cauda equina syndrome (CES) in this disease. CT showed a dorsal arachnoid diverticulum causing scalloped erosion of the laminae, and punctate and curvilinear dural calcification. MRI revealed adhesion and convergence of the cauda equina dorsally into the arachnoid pouch, causing the dural sac to appear empty canal. To the best of our knowledge, dural calcification on CT is a new finding in AS, which may be related to the CES. Our findings support the hypothesis that chronic adhesive arachnoiditis with subsequent loss of meningeal elasticity may be the main cause of CES in AS.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
4/39. median nerve palsy presenting as absent elbow flexion: a result of a ruptured pectoralis major to biceps tendon transfer.We describe a patient with a preexisting posttraumatic brachial plexopathy who had a complete high median nerve palsy due to rupture of the pectoralis major to biceps transfer near its distal insertion at the elbow region.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
5/39. Bilateral peroneal nerve palsy induced by prolonged squatting.External or internal pressures on peripheral nerves may result in compression neuropathies. Although compressive common peroneal nerve palsy is well known, to date very few cases with bilateral palsies have been reported. The clinical and electrophysiological manifestations of three patients with bilateral peroneal nerve palsies are reported, and their clinical outcomes are discussed. The first patient's transient bilateral palsy was corrected by conservative means. The second patient, with a more severe axonal lesion, did not improve within 3 months, and nearly complete recovery occurred after operative decompression. For the third patient, who had been suffering for a long time, no improvement could be hoped for. Prolonged squatting was the etiological factor in all three cases. Bilateral compression neuropathies of the peroneal nerve, like unilateral lesions, may recover spontaneously. Surgical intervention is recommended for patients with predominantly axonal lesions and for those who do not improve within 3 months.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
6/39. Superior cluneal nerve entrapment.BACKGROUND AND OBJECTIVES: Pain due to superior cluneal nerve entrapment is an infrequent cause of unilateral low back pain. Here we present a case of acute unilateral low back pain treated by superior cluneal nerve (SCN) block. CASE REPORT: A 55-year-old woman presented to the outpatient clinic suffering from unilateral low back pain localized to right iliac crest and radiating to the right buttock. Her history was taken, physical examination was performed, and a thorough radiologic evaluation was performed to minimize radiculopathy and facet syndromes as causative. After transient pain relief with a diagnostic trigger point injection, entrapment of SCN was diagnosed and therapeutic nerve block with local anesthetic and steroid combination was performed. CONCLUSION: SCN is prone to entrapment where it passes through the fascia near the posterior iliac crest. Unilateral low back pain and deep tenderness radiating to the ipsilateral buttock are the clinical findings accompanying SCN entrapment. The case presented emphasizes the relief of possible SCN after limiting other etiologic causes of low back pain.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
7/39. Radial entrapment neuropathy due to chronic injection-induced triceps fibrosis.We report two patients who developed progressive, severe, painless radial neuropathies (bilateral in one, unilateral in the other) as a delayed complication of chronic intramuscular analgesic injection. In each instance, exploration of the radial nerve revealed multifocal entrapment within a densely fibrotic triceps muscle at sites between the spiral groove and distal course of the radial nerve near the elbow. Release of the nerve from constriction within the fibrotic triceps muscle produced improvement in all three affected nerves.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
8/39. Ilioinguinal nerve entrapment after tension-free vaginal tape (TVT) procedure.The anatomy of the ilioinguinal nerve makes it vulnerable to entrapment near its exit from the superficial inguinal ring, where it lies almost directly superior to the pubic tubercle. Ilioinguinal nerve entrapment is a documented complication of inguinal herniorrhaphy, inguinal lymph node dissection, appendectomy, Pfannenstiel incision and the needle suspension procedure. It has not previously been described as a complication of the tension-free vaginal tape (TVT) procedure, which is the most recent technique for the treatment of genuine urinary stress incontinence. This paper describes a clinical history to illustrate the diagnosis and management of ilioinguinal nerve entrapment occurring as a complication of tension-free vaginal tape procedure.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
9/39. Clinical case seminar: Riedel's thyroiditis: report of a case complicated by spontaneous hypoparathyroidism, recurrent laryngeal nerve injury, and Horner's syndrome.A 42-yr-old woman presented with hyperthyroidism and a large, firm, irregular goiter. Within a few weeks she became hypothyroid. Five months later she developed increasingly severe neck pain and compressive symptoms. The goiter had become rock hard. A fine needle aspiration biopsy showed features of chronic thyroiditis and fibrosis. She partially responded to a course of glucocorticoids. tamoxifen was added, with marked improvement in goiter size and pain. Both medications were tapered off. Two months later the patient experienced paresthesias of the fingertips, perioral numbness, and a seizure. She was found to have spontaneous primary hypoparathyroidism. Three months later the patient became hoarse and experienced difficulty in breathing. She was found to have a massively enlarged thyroid with compression of the right internal jugular vein and encasement of the right carotid artery as well as tracheal narrowing. She also had right vocal cord paralysis due to recurrent laryngeal nerve involvement. Because of airway compromise, an emergency isthmusectomy was performed, and the patient was given a postoperative course of glucocorticoids with gradual improvement. Postoperative diagnosis was Riedel's thyroiditis. Two months later she presented with near-syncope and was found to have bradycardia, hypotension, and right Horner's syndrome, presumably due to compression of the right carotid sheath. She was given i.v. glucocorticoids and tamoxifen. Six months later and 18 months after her initial presentation, the patient is doing remarkably well. Her goiter has regressed by more than 50%, and she no longer has any pain or difficulty breathing. She remains a little hoarse and has persistent hypothyroidism and hypoparathyroidism. She is taking prednisone (5 mg, this is being tapered very slowly) and tamoxifen (20 mg) daily. This case illustrates the protean manifestations of Riedel's thyroiditis, a rare but fascinating disease. The epidemiology of this disease, its pathophysiology and complications, and the roles of surgery and medical therapy are reviewed.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
10/39. Concomitant compression of median and ulnar nerves in a hemophiliac patient: a case report.A 15-year-old boy, with a diagnosis of hemophilia a, suffered bleeding into his left forearm 5 months before being admitted to our medical center. His neurological examination revealed a pronounced median neuropathy and a minor ulnar neuropathy on the left side. There was marked muscle atrophy on the thenar side and, to a lesser degree, on the hypothenar side and in the forearm. Electromyographic findings demonstrated an evident, nearly complete, sensorimotor axonal loss in the median nerve. magnetic resonance imaging studies showed atrophy in muscles of the left forearm and median nerve. The patient was diagnosed as having median nerve axonotmesis and ulnar nerve neuropraxia due to compartment syndrome. In hemophiliac patients, frequent single nerve compressions (often involving the femoral nerve) can be seen. However, concomitant median and ulnar nerve injuries with differing severity are rare.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
