Background: Headache is one of the most common causes of emergency care and migraines are the most common primary headache in this regard. Objective: The aim of this research study was to assess the incidence of medical consultations due to headache, along with demographic characteristics and treatments pertaining to cephalalgia that were offered to patients cared for in supplemental healthcare emergency rooms. Methods: In 2017, a total of 11,105 consultations took place, and 4,865 (43.8%) of them were complaints relating to headache. 407 records of patients with headache were randomly selected and assessed. Demographic, clinical and therapeutic data were collected using a structured form. Results: The cause of headache was diagnosed as migraine in 60.0% of the patient records. Patients were mostly female (75.2%), with an average age of 33.9 ± 13.7 years. Patient management consisted of administering dipyrone in 62.4% of cases, antiemetics in 66.9%, corticosteroids in 58.9%, opioids in 24.3% and NSAIDs in 13.5%. Use of opioids was associated with a diagnosis of migraine (OR 2.4; CI 1.4-3.9; p = 0.001). Patients who received opioids were kept under observation for longer periods of time (OR 3.4; CI 2.1-5.4; p < 0.001) and exhibited a higher rate of use of antiemetics (OR 11.0; CI 4.7-25.9; p < 0.001), compared with patients who did not receive opioids. Conclusion: Dipyrone and antiemetics were administered to most of the patients. Opioids were used for a significant proportion of these individuals, despite the diagnosis of migraine, a condition for which their use is discouraged. RESUMO Introdução: Cefaleia é uma das causas mais frequentes de atendimentos de emergência, sendo que a migrânea é a cefaleia primária mais comum nesse contexto. Objetivo: Avaliar a frequência de atendimentos por cefaleias, bem como as características demográficas e o tratamento oferecido aos pacientes atendidos em Pronto Atendimento da Saúde Suplementar. Métodos: No ano de 2017 foram realizados 11.105 atendimentos, sendo 4.865 (43,8%) por queixa de cefaleia. Foram selecionados randomicamente a analisados 407 prontuários de pacientes com cefaleia. Os dados demográficos, clínicos e terapêuticos foram coletados através de formulário estruturado. Resultados: A causa da cefaleia foi diagnosticada como migrânea em 60,0% dos prontuários. Os pacientes eram em sua maioria do sexo feminino (74,9%), com média de idade de 33,9±13,7 anos. O manejo dos pacientes constitui-se na administração de dipirona em 62,4%, antiemético 66,9%; corticóide 58,9%, opióide 24,3% e, por fim, AINE foi utilizado em 13,5% dos casos. O uso de opióide foi associado ao diagnóstico de migrânea (OR 2,4; CI 1,4-3,9; p=0,001). Pacientes que receberam opióide também tiveram maior tempo de permanência (OR 3,4; IC 2,1-5,4; p

We present the case of a 47 years old woman submitted to an endovascular trapping of a left cavernous internal carotid artery aneurysm, in which the distal balloon was inflated, as usually done, within the cavernous segment of the internal carotid artery, different from the proximal one which was inflated inside the carotid canal due to technical problems. Consequently, a clinical picture of Raeder's paratrigeminal neuralgia took place. This is the first case report in the literature with theses characteristics. A review of the anatomic pathways and further considerations about the possible pathophysiological mechanisms involved are presented.

The group comprises episodic and chronic clus-ter headache, chronic and episodic paroxysmal hemicra-nia, and SUNCT syndrome. SUNA syndrome (short-lasting unilateral neuralgiform headache attacks with cranial au-tonomic symptoms), although not classified as a TAC, also shares some common characteristics with this group and may include the SUNCT definition. Despite their common elements, the TACs differ in response to therapy, frequen-cy and duration of attacks. They must be differentiated from secundary TACs because of the possible serious and treatable underlying causes, like mass lesions, subarach-noid hemorrhage, pathology in the base of the skull and others

Spontaneous intracranial hypotension is a rare syndrome associated with postural cephalalgia and low pressure of the cerebrospinal fluid. We report the case of a 45 years-old man with spontaneous intracranial hypotension with MRI diffuse meningeal enhancement.

CASE A 50-year-old male patient sought medical care com -plaining of cephalalgia for 4 months, diplopia and ptosis of the left eyelid for 30 days. He reported loss of libido and erectile dysfunction in the previous six months. He was before a salutary individual. Physical examination: body mass index (BMI) 24, with ptosis and ophthalmo-plegia of the left eye, arterial pressure of 140/80 mmHg. No other alterations. Magnetic resonance imaging (Figure) showed hetero -geneous mass into the sella turcica with suprasellar ex-tension, causing displacement of optic chiasm and third ventricle floor, with intense opacification after contrast.The laboratory exams showed normal thyroid func-tion, low levels of gonadotropins and total testosterone, normal levels of basal cortisol and IGF-1 and very small increase in serum prolactin. Renal function, serum so-dium and urine density were within normal limits. Cen -tral hypogonadism and slight hyperprolactinemia were de -tected, without evidence of posterior pituitary alteration. An endoscopic transsphenoidal pituitary surgery were performed and anatomopathological exam showed metastasis of moderately differentiated adenocarcinoma of unknown primary site. Postoperative exams showed anemia, increased GGt, FA and CA 19-9. Immunohisto -chemical analysis indicated origin in the gastrointestinal tract, imaging of thorax and abdomen showed lymphade -nopathies and small irregularities on the antral mucosa wall of the stomach. Upper gastrointestinal endoscopy with biopsy showed stomach antral adenocarcinoma.DISCUSSIONMetastatic tumors of the pituitary gland are rare complications
