Pancoast or superior pulmonary sulcus tumors are uncommon primary bronchogenic carcinomas that produce a characteristic clinical syndrome of upper extremity pain and Horner's syndrome. Treatment of patients with this malignancy has traditionally involved irradiation alone or preoperative irradiation followed by resection. Recent advances in the management of Pancoast tumors include the importance of mediastinoscopy in staging the tumor before treatment begins. A complete resection should be accomplished including a lobectomy whenever possible. The current treatment protocol involves induction chemoradiotherapy followed by surgery.

While performing the anterior approach to the cervical vertebral bodies, injury to important anatomic structures in the vicinity of the dissection represents a serious risk. The midportion of the recurrent laryngeal nerve and the external branch of the superior laryngeal nerve are encountered in the anterior approach to the lower cervical spine. The recurrent laryngeal nerve is vulnerable to injury on the right side, especially if ligation of inferior thyroid vessels is performed without paying sufficient attention to the course and position of the nerve, and the external branch of the superior laryngeal nerve is vulnerable to injury during ligature and division of the superior thyroid artery. Avoiding injury to the recurrent laryngeal nerve (especially on the right side) and superior laryngeal nerve is a major consideration in the anterior approach to the lower cervical spine. The sympathetic trunk is situated in close proximity to the medial border of the longus colli at the C6 level (the longus colli diverge laterally, whereas the sympathetic trunk converges medially). The damage leads to the development of Horner's syndrome with its associated ptosis, meiosis, and anhydrosis. Awareness of the regional anatomy of the sympathetic trunk may help in identifying and preserving this important structure while performing anterior cervical surgery or during exposure of the transverse foramen or uncovertebral joint at the lower cervical levels. Finally, the spinal accessory nerve (embedded in fibroadipose tissue in the posterior triangle of the neck) is prone to injury. Its damage will result in an obvious shoulder droop, loss of shoulder elevation, and pain. Prevention of inadvertant injury to the accessory nerve is critical in the neck dissection.

Homer's syndrome, which classically presents as ipsilateral ptosis, meiosis, and facial anhydrosis, may present as a consequence of thoracic epidural analgesia. Pain that limits the patient's ability to maintain adequate pulmonary mechanics may optimally be treated with a thoracic epidural. The importance of recognition of a Horner's syndrome in such a patient is critical in preventing unnecessary anxiety for the patient and potentially embarking on an unnecessary diagnostic workup. The following is a case presentation of a patient who sustained multiple rib fractures in an automobile accident. The patient presented with a Horner's syndrome after a thoracic epidural infusion had begun. This article highlights the importance of early recognition of this benign, transient syndrome and discusses the pathways and potential mechanism of this process.

Pancoast's syndrome refers to a condition consisting of Horner's syndrome and arm pain that is most commonly found in patients with a lung tumor of the superior sulcus invading the upper ribs or spine, lower brachial plexus and sympathetic chain. We report a 76-year-old female who had a thoracic inlet mass that presented as Pancoast's syndrome, showing profound pain, numbness and weakness of the left upper limb. Further evaluation revealed an increased level of serum alpha-fetoprotein (24278 ng/ml), cryptogenic liver cirrhosis and primary hepatocellular carcinoma with protruding T3 vertebra metastasis that resulted in Pancoast's syndrome. To our knowledge, it is a rare case and only one case has been reported previously.

Sympathetically maintained pain syndrome of the upper limb is difficult to treat even with high doses of specific medication. Stellate ganglion block by in situ injection of a local anesthetic is an efficient and accepted method for diagnosis and treatment. The sedative effect is however transitory linked to the short effect of the drug. CT guidance, displaying an excellent contrast between soft tissues, bones, vessels and nerves, is a well suited and safe mean of guidance. Seven patients suffering from reflex sympathetic dystrophy were treated by stellate ganglion radiofrequency (RF) neurolysis at two sites (C7 and T1). Patients were evaluated for pain before and immediately after the procedure and at three months. Four patients had a significant (50%) pain relief lasting at 3 month. One patient had a temporary pain (one week) and 2 no pain relief. No patient had a Horner syndrome. One patient had a temporary neuralgia of surrounding nerves (brachial plexus). RF neurolysis of stellate ganglion under CT-guidance is precise and appears efficient but further investigation on a larger cohort of patients is needed.

A 50-year-old man complained of headache around his left orbit, left frontal pain and paresthesia associated with left incomplete Horner syndrome. MRI demonstrated a mass at the level of medulla oblongata. Left vertebral angiogram revealed an aneurysm of left vertebral artery. Following the removal of the aneurysm, these Raeder's syndrome-like symptoms improved. Therefore, they were probably caused by a compression of the spinal tract of the trigeminal nerve and the central sympathetic tract by the aneurysm. This is the first report of Reader's syndrome-like symptoms caused by vertebral artery aneurysm, thus indicating that MRI and cerebral angiogram are necessary for differential diagnosis of this 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.

Gross and microscopic anatomical evidence indicates that pain fibers involved in causalgia are those distributed to blood vessels-possibly to the arterioles-and that, for the greater part, these fibers constitute part of the general visceral afferent system. Several investigators have reported evidence that injury to a peripheral nerve of such a type as to cause damage to the vasomotor control of any area produces the initial pain in an extremity, and it is predicated that the arteriolar constriction causing the pain is then prolonged by the sensitization of arteriolar smooth muscle to the amount of epinephrine normally in the blood. If the condition is not treated, tissue anoxia occurs to such an extent that irreversible changes take place in the affected area.Treatment of causalgia in the lower extremities is directed toward interruption of either the vasomotor or afferent supply of blood vessels by blocking or excision of the second to fourth lumbar ganglia inclusive with the intervening chains. For the upper extremities, the blocking or disconnection of the second and third thoracic ganglia with interruption of the sympathetic chain between the third and fourth ganglia is considered a feasible method of treatment which does not produce the concomitant disability of Horner's syndrome.

In young and middle age subjects, spontaneous carotid dissection is an increasingly recognized cause of ischemic stroke. Their usual presentation is facial pain with a Horner syndrome and a contra lateral paresis. Blindness has been reported as a presenting symptom in only a few cases. We report a 50 years old man who presented with amblyopia in the left eye, without periocular pain. Fundoscopy showed papilledema and a peripapillar hemorrhage, compatible with an ischemic optic neuropathy. A magnetic resonance angiography confirmed a left carotid dissection.
