Cerebral venous thrombosis presenting with subarachnoid hemorrhage (SAH) is very rare. We report a case of cerebral venous sinus thrombosis as an initial manifestation of SAH. A 14-year-old boy was admitted with progressive headache, nausea, vomiting, diplopia, and gait disturbance. Cerebral computed tomography scan showed a widely SAH in the basal cisterns, bilateral sylvian fissures, and anterior interhemispheric fissure. Cerebral angiography was performed to detect any aneurysm in intracranial vasculature as a cause of SAH; however, the totally thrombosed superior sagittal sinus, galenic vein, and straight sinus were the sole abnormal findings.

Ziconotide intrathecal infusion was recently approved by the United States Food and Drug Administration for the treatment of intractable severe chronic pain. Patients with neuropathic pain make up a significant population among those who experience chronic pain for which there are less than optimal pharmacotherapeutic options. Published clinical trials provide a global view of ziconotide efficacy and safety. A subset of patients in clinical trials obtained complete pain relief, a remarkable finding given the history of drug treatment for neuropathic pain. To provide more information regarding those who respond to ziconotide therapy, we discuss three patients with neuropathic pain who received ziconotide infusion. Two patients with longstanding neuropathic pain, one with complex regional pain syndrome (formerly known as reflex sympathetic dystrophy) of the leg and one with lumbar radiculitis, achieved temporary but complete pain relief from single 5- and 10-microg epidural test doses. In the third case, a patient with longstanding bilateral leg and foot neuropathic pain from acquired immunodeficiency syndrome and antiretroviral drug therapy achieved considerable pain relief from a long-term continuous intrathecal infusion. The patients who received a single dose had mild central nervous system adverse effects such as sedation, somnolence, nausea, headache, and lightheadedness. The patient who received the intrathecal infusion experienced mild-to-severe adverse effects depending on the rate of infusion; these effects included sedation, confusion, memory impairment, slurred speech, and double vision. This patient could sense impending adverse effects and made rate adjustments or suspended infusion to avert untoward symptoms. In all three cases, patients achieved considerable pain relief that was long-lasting and persisted well after dose administration or suspension of infusion.

Post-dural puncture headache (PDPH) also known as spinal (or post-spinal) headache still remains a disabling complication of needle insertion into the subarachnoid space. Pregnant women are at particular risk of dural puncture, and the subsequent headache, because of sex, young age, and the widespread application of regional anesthesia. Accidental dural puncture complicating epidural anesthesia varies in incidence from 0.19 to 4.4%. The incidence of epidural needle-induced PDPH headache in pregnant women has been reported to range 76-85%. The classic symptoms of PDPH consist of photophobia, nausea, vomiting, neck stiffness, tinnitus, diplopia, and dizziness in addition to the often, severe cephalgia. This article reviews the current literature on the pathophysiology, incidence, prevention, and treatment of PDPH in pregnant women.

Cerebrospinal fluid (CSF) volume depletion syndrome is due to leakage of cerebrospinal fluid through lesions of the dural sac at the level of the cranial base or of the spine. When past medical history is negative for recent trauma or surgery, the term spontaneous intracranial hypotension (SIH) is used. SIH is characterized clinically by orthostatic headache, neck pain, nausea, emesis, horizontal diplopia, tinnitus, plugged ear, hearing difficulties, blurring of vision, facial numbness, and upper limb radicular symptoms. In SIH, brain and cervical MR scans show a diffuse pachymeningeal gadolinium enhancement that ends at the site of CSF leakage. The application of epidural blood patches has been proposed as an effective therapy for SIH. Here we describe a case of SIH with very unusual headache features; the patient reported a paradoxical pattern of postural headache provoked by clinostatic position. The CSF leakage was identified at the convexity of the skull and headache disappeared following treatment with fluid, analgesics and steroids.

Clinically unsuspected pituitary adenomas are common among adults on autopsy and MRI survey. Acute pituitary hemorrhage is far more rare. We report a case of a 61-year-old male patient with locally advanced prostate cancer who presented with an acute picture of pituitary apoplexy after his first dose of leuprolide. He developed headache and neck pain within a few hours of treatment followed by nausea, vomiting, ptosis and diplopia. Pituitary apoplexy is a potentially life threatening medical emergency. Although the pathophysiology is poorly defined, various conditions and treatments have been reported to trigger apoplexy. Apoplexy has been reported in response to pituitary stimulation by GnRH or GnRH-agonists. Initial stimulatory effects of gonadotropin releasing hormone (GnRH) analogue may induce apoplexy in patients with asymptomatic gonadotroph adenomas.

Cerebrospinal fluid (CSF) volume depletion, due to CSF leakage or CSF shunt overdrainage, is typically indicated when patients present with orthostatic headaches, with or without several other symptoms: neck or interscapular pain, nausea, emesis, diplopia, changes in hearing, visual blurring, facial numbness or weakness, and radicular upper-limb symptoms. Cerebrospinal fluid pressures typically are quite low and head magnetic resonance images typically reveal diffuse pachymeningeal gadolinium enhancement, with or without evidence of sagging of the brain and less frequently with subdural fluid collections, enlarged cerebral venous sinuses or pituitary gland or decreased ventricular size. Magnetic resonance imaging has revolutionized detection of spontaneous CSF leaks, leading to identification of far more cases and recognition of several clinical/imaging forms of presentation of the disorder. These forms, which are different from the "typical" presentation, include a group with consistently normal CSF pressures (normal pressure), another group without abnormal meningeal enhancement (normal meninges), and a group without headache (acephalic). Each of these forms can be seen in a setting of documented and ongoing CSF volume depletion. Awareness of CSF volume depletion is increasing, and its clinical and imaging spectrum is broadening.

Spontaneous spinal cerebrospinal fluid (CSF) leaks are an increasingly recognized cause of intracranial hypotension. In this report the authors review the indications for surgery, surgical techniques, and surgery-related outcomes for these lesions. The major presenting symptoms include postural headaches, nausea, vomiting, and diplopia. Often, there is no history of traumatic injury. The most common cranial magnetic resonance (MR) imaging features include pachymeningeal gadolinium enhancement and sagging of the brain. On spinal MR images, diverticula are frequently noted. In cases in which symptoms are severe and refractory to less invasive measures, surgical intervention is indicated. Tears in the dura or leaking diverticula that are identified as the sources of the CSF leak often can be ligated or repaired. When a source of CSF egress is not found intraoperatively, packing the epidural space with blood-soaked Gelfoam or muscle at the appropriate level can lead to relief of symptoms. Occasionally the dural defect is large, irregular, or has attenuated borders that may not be possible to repair with sutures. These may be repaired by packing the defect with muscle or blood-soaked Gelfoam. Indications for and outcomes of surgery in patients with this condition will become more defined as surgeons gain experience with these procedures.

Temporal arteritis is a rheumatic disease that affects large and medium-sized arteries. It is a severe arteritis involving both the intima and media of the vessel and is a cause of headache that is frequently diagnosed erroneously as "atypical migraine." The patients have a burning or throbbing type of pain. Ultimately, there is localized inflammation or cellulitis over the swollen, tortuous artery. Jaw claudication, eye pain, photophobia, diplopia, and even blindness may accompany the temporal symptoms. As many as 20% to 60% of inadequately treated or untreated patients will lose their vision. Blindness may or may not be preceded by visual symptoms and funduscopic changes. A variety of systemic symptoms are also often present, including nausea, vomiting, chills, dizziness, and loss of weight. Temporal arteritis is not a common diagnosis in maxillofacial practice. We are presenting a case of temporal arteritis diagnosed after a biopsy. The patient eventually lost the vision from one eye.

Pituitary abscess secondary to an adenoma is rare. To date, only 19 cases have been reported. This is the first report of a patient who presented with bilateral total ophthalmoplegia. A 59-year-old male patient presented with headache, nausea, vomiting, decreasing visual acuity, diplopia and bilateral ophthalmoplegia with ptosis. Magnetic resonance imaging was suggestive of a pituitary abscess with adenoma. Transphenoidal surgery was performed and, during debulking of the tumour, the abscess was seen and excised. After the operation, the patient received antibiotic therapy and his neurological condition improved. Pituitary abscess with adenoma is a serious condition that has a high mortality rate. Therefore, early diagnosis and surgical intervention with antibiotic therapy are necessary.

A 70-year-old patient treated with oxcarbazepine experienced severe hyponatremia. The patient used oxcarbazepine (600 mg twice a day) concomitantly with diuretics (torasemide 10 mg and indapamide 1.25 mg once per day), perindopril, an angiotensin-converting enzyme inhibitor, and amlodipine, a Ca(2+) channel blocker. The patient complained of a nausea, malaise, diplopia, drowsiness, apathy, decreased diuresis (creatinine clearance - 41.51 ml/min), and exacerbation of epileptic seizures. Sodium concentration in the plasma was 113 mmol/l. The patient was hospitalized. It was suggested that a decrease in plasma sodium concentration was caused by oxcarbazepine used together with diuretics for six months. Oxcarbazepine-induced hyponatremia is reported in 22.2-50% of patients, although symptoms are present only in 5.9% of patients. The most common symptoms of central nervous system injury, experienced by patients, are drowsiness, dizziness, decreased cognitive function, coordination impairment, etc. Physicians not always in time pay proper attention to undesirable antiepileptic drug-induced effects, which can be dangerous.
