ABSTRACT
Se presenta un caso de una paciente con pérdida de peso, congestión nasal epistaxis, aumento de volumen en cuello con disfagia a sólidos y líquidos de 1 mes de evolución. La tomografía de cuello muestra una masa de tejidos blandos en la base de cuello con erosión del esfenoides con extensión a la fosa craneal media, con erosión del clivus, el esfenoides y la silla turca. El diagnostico histopatológico es un estesioneuroblastoma.
We present a case of a patient with weight loss, nasal congestion, epistaxis, increase neck volu me with dysphagia to solids and liquids of 1 month of evolution. The neck tomography shows a soft tissue mass at the base of the neck with erosion of the sphe noid with extension to the middle cranial fossa, with erosion of the clivus, the sphenoid and the sella turcica. The histopathological diagnosis is an esthesioneuroblastoma.

Los osteomas fronto-etmoidales son los tumores benignos más frecuentes de los senos paranasales, pudiendo evolucionar con complicaciones por compresión de estructuras adyacentes. Se presenta el caso de una paciente de 63 años de edad, que consultó por aumento de volumen nasofrontal, cefalea y diplopía. Tras el examen clínico, se evidenció una asimetría facial con lateralización del bulbo ocular derecho y exoftalmo. La tomografía de los senos paranasales mostró una lesión que ocupa parcialmente el seno frontal, etmoidal y parte de la cavidad nasal. Los cuidados anatómicos y planificación quirúrgica se desarrollaron en un modelo estereolitográfico mientras que la cirugía de exéresis total se realizó con ayuda del sistema piezoeléctrico. El examen histológico confirmó el diagnostico de osteoma. Se obtuvo una reconstrucción exitosa, recuperando totalmente simetría y función ocular.
Fronto-ethmoidal osteomas are the most frequent benign tumors of the paranasal sinuses, and may evolve with complications by compression of adjacent structures. The case is a 63-year-old female patient, who consulted about increased nasofrontal volume, headache and diplopia. After the clinical exam, she presented a facial asymmetry with lateralization of the right eyeball and exophthalmus. Computed tomography of the sinuses showed a lesion that partially occupies the frontal sinus, ethmoidal sinus and part of the nasal cavity. The anatomical care and surgical planning was developed in a stereolithographic model while the total excision surgery was performed with the help of the piezoelectric system. Histological examination confirmed the diagnosis of osteoma. A successful reconstruction is obtained, fully recovering symmetry and ocular function.

Nasal dermoids are rare congenital anomalies, which usually present in early childhood as a midline nasal mass that requires surgical management. It is important to rule out any intracranial extension before subjecting the patient to surgery. We describe a case of nasal dermoid with intracranial extension. The embryology of the formation of the nasal dermoid, cyst and sinus, with the role of CT scan and MRI in diagnosing intracranial extension, and its management are discussed.

Os autores relatam o caso de um meningioma gigante de rima olfatória num paciente masculino, preto, de 42 anos submetido à cirurgia de exerese do tumor. Os meningiomas säo tumores originários da proliferaçäo de células meningoteliais da aracnóide näo marcadamente anaplásicas, sendo considerados tumores benignos do ponto de vista histológico. Ocorrem mais comumente da quarta à sexta década de vida, com pico aos 45 anos. Aproximadamente 65 por cento säo mais freqüentes no sexo feminino, porém, a partir dos 65 anos, essa predominância é perdida. Constituem 35 por cento dos tumores cerebrais, sendo a maioria intracranianos e supratentoriais. A sobrevida dos pacientes com meningioma gigante da rima olfatória é alta quando feita a ressecçäo completa do tumor, apesar de o procedimento cirúrgico ser muito delicado.
