Abstract: Cerebral extra-axial metastasis mimicking meningioma which satisfy several criteria for a diagnosis of meningioma, but which have proved instead to be metastatic carcinoma and extremely delayed cerebral metastasis from renal cell carcinoma form the focus of the presentation. 68-year-old-woman who had been operated for renal cell carcinoma 20 years previously is presented with new symptoms of intracranial mass. A large extraaxial mass of the convexity which destroyed calvarium and dura was excised with Simpson Grade I removal, revealed metastatic carcinoma. Imaging characteristics can not always discern between meningioma and metastatic tumours. A meticulous clinical evaluation and histopathological diagnosis is essential in patients with intracranial mass even they resemble both primary and metastatic tumours. Se presenta un caso de metástasis craneal extra-axial, que satisface varios criterios para el diagnóstico de meningioma, en el cual se demostró que se trataba de la metástasis tardía de un carcinoma renal. Una paciente de 61 a os, que había sido operada de un carcinoma renal 20 a os antes, se presentó con síntomas de un tumor cerebral. Se extirpó un gran tumor extra-axial de la convexidad, que destruía la bóveda craneal y la duramadre, (Simpson grado I), pero que reveló se trataba de una metástasis. Las imágenes de estas característica no siempre pueden discernir entre un meningioma y una metástasis. Es esencial realizar una meticulosa valoración clínica y un diagnóstico histopatológico en pacientes con tumores intracraneales, aunque parezcan tumores metastáticos.

Abstract: idiopathic hypertrophic pachymeningitis (ihpm) is a rare inflammatory entity characterized by the idiopathic thickening of the dura mater. an increasing number of cases have been reported involving the cavernoss sinus. we present the case of a patient with ihpm who was diagnosed of meningioma and showed a complete occlusion of the intracavernous carotid ailery. this 42 years old woman was sent to our hospital to be treated radiosurgicaly with the diagnosis of meningioma. the diagnosis was based on mri findings and on the temporal resistance to corticoid treatment. a complete study of the patient demonstrated the inflammatoiry nature of the lesion, which improved after long corticosteroid treatment. the differential diagnosis between meningioma and ihpm may be complex because of the similarities in image findings and the temporal resistance to corticosterods shown by ihpm, thus we emphasize the usefulness of the spect to differentiate between inflammation and tumor in this clinical setting. in addition, our patient showed a total occlusion of the intracavernous carotid artery and, as far as we know, this is the first case with such a finding reported in the literature.

Abstract: La paquimeningitis crónica hipertrófica (PMCH) es una rara entidad inflamatoria caracterizada por la hipertrofia crónica idiopática de la duramadre. La afectación del seno cavernoso, aunque rara, ha sido reportada con mayor frecuencia en los últimos a os. Presentamos el caso de una paciente con PMCH que fue inicialmente diagnosticada de meningioma y en la que se evidenció oclusión completa de la arteria carótida intracavernosa. Esta paciente de 42 a os fue enviada a nuestro centro con el diagnóstico de meningioma para recibir tratamiento radioquirúrgico. El diagnóstico inicial se basó en la imagen de RM y en la falta de respuesta temporal a los esteroides. Un estudio completo evidenció la naturaleza inflamatoria de la lesión, la cual mejoró tras prolongado tratamiento corticoideo. El diagnóstico diferencial entre PMCH y meningioma puede ser difícil debido a las similitudes en las pruebas de imagen y a la resistencia temporal a los corticoides que puede presentar la PMCH. Por ello enfatizamos la utilidad del SPECT para diferenciar las entidades tumorales de las inflamatorias. Nuestra paciente presentó además la peculiaridad de mostrar una oclusión completa de la arteria carótida intracavernosa, circunstancia que no hemos encontrado reportada en la literatura. Idiopathic hypertrophic pachymeningitis (IHPM) is a rare inflammatory entity characterized by the idiopathic thickening of the dura mater. An increasing number of cases have been reported involving the cavernoss sinus. We present the case of a patient with IHPM who was diagnosed of meningioma and showed a complete occlusion of the intracavernous carotid ailery. This 42 years old woman was sent to our hospital to be treated radiosurgicaly with the diagnosis of meningioma. The diagnosis was based on MRI findings and on the temporal resistance to corticoid treatment. A complete study of the patient demonstrated the inflammatoiry nature of the lesion, which improved after long corticosteroid treatment. The differential diagnosis between meningioma and IHPM may be complex because of the similarities in image findings and the temporal resistance to corticosterods shown by IHPM, thus we emphasize the usefulness of the SPECT to differentiate between inflammation and tumor in this clinical setting. In addition, our patient showed a total occlusion of the intracavernous carotid artery and, as far as we know, this is the first case with such a finding reported in the literature.
Intraventricular meningioma

Journal of Neurological Sciences , 2004,
Abstract: Intraventricular meningiomas are quite rare and they represent an important differential diagnosis of intraventricular neoplasms. In this report we present two cases of primary intraventricular meningioma. In both cases preoperative computed tomography and magnetic resonance imaging revealed contrast-enhancing mass lesions with in the lateral ventricles. The tumors were totally resected via a transparietal approach. The histological diagnosis revealed as meningioma. As a result it is difficult to diagnose intraventricular meningiomas only with radiological images.

Indian Journal of Dermatology , 2008,
Abstract: Primary extracranial meningiomas occur very rarely. We present a rare case of extracranial meningioma of the transitional variant which was excised satisfactorily. There was no suggestion of any connection to the intracranial compartment or cranial nerves. The underlying galea was uninvolved, suggesting the true extracranial nature of this tumour. This rare diagnosis should nonetheless be kept in the differential diagnosis of scalp tumors.

Abstract: OBJETIVO: presentar un paciente con un meningioma quístico, hallazgo infrecuente en la práctica neuroquirúrgica. DESCRIPCIóN: paciente de sexo femenino, de 66 a os de edad, con antecedentes de salud, quien fue llevada al cuerpo de guardia por presentar convulsiones. El examen físico resultó negativo. Los hallazgos obtenidos en la tomografía simple y contrastada hicieron pensar en el diagnóstico de tumor cerebral primario, probable astrocitoma de bajo grado vs. hemangioblastoma, que por su localización parietal alta podría justificar el cuadro clínico de la paciente. INTERVENCIóN: se realizó tratamiento quirúrgico, con posterior examen histopatológico, y se detectó un meningioma angiomatoso. CONCLUSIONES: los meningiomas quísticos constituyen un hallazgo infrecuente en la práctica neuroquirúrgica, no obstante, no se debe olvidar que existen varios signos imagenológicos que orientan al diagnóstico preoperatorio como la existencia del signo de la cola, la irrigación procedente de la carótida externa o la ubicación en sitios de asentamiento frecuente de meningiomas. OBJECTIVE: the presentation of a patient with cystic meningioma an uncommon finding in the neurosurgical practice. DESCRIPTION: a female patient aged 66 with health history seen in emergency department due to convulsions. The physical examination was negative. The findings obtained in single and contrasted tomography to bring about the diagnosis of primary cerebral tumor, a low grade probable astrocytoma versus hemangioblastoma which due to its parietal location could to justify the clinical picture of the patient. INTERVENTION: surgical treatment with a subsequent histological-pathological examination detecting the presence of an angiomatous meningioma. CONCLUSIONS: the cystic meningiomas are a uncommon finding in the neurosurgical practice, however, we must to take into account the there are some imaging signs leading to the preoperative diagnosis as the presence of tail sign, the irrigation of the external carotid or the location in sites of frequent settlement of meningiomas.

Abstract: Se presenta el caso clínico de un paciente que comenzó a presentar cefalea, vértigos, trastornos visuales y pérdida del equilibrio. Mediante la resonancia magnética se visualizó una imagen tumoral parietal izquierda de 3 cm diámetro, de localización extraaxial y contornos lobulados bien definidos, con gran captación no homogénea de contraste, rodeada de extenso edema perilesional. Se realizó angiotomografía, previa a la cirugía, en busca de irrigación y da o vascular. Se logró la resección de 95% de la lesión (grado II de Simpson), que incluyó duramadre adyacente infiltrada y respetó el seno longitudinal superior. Los resultados anatomopatológicos confirmaron que se trataba de un meningioma anaplásico de grado III, con criterio de tratamiento coadyuvante. The case report of a patient who began presenting headache, vertigos, visual disorders and loss of balance is presented. By means of the magnetic resonance a left tumoral parietal image of 3 cm diameter was visualized, of extra-axial localization and well defined lobulated contours, with great non-homogeneous zones of contrast, surrounded by extensive perilesional edema. An angiotomography was carried out, previous to the surgery, looking for irrigation and vascular compromise. The resection of 95% of the lesion was achieved (grade II of Simpson) which included adjacent infiltrated dura madre and preserving the superior longitudinal sinus. Pathological results confirmed that it was an anaplastic meningioma grade III, with criterium for adyuvant treatment.
