ABSTRACT

A case of metastasis of breast adenocarcinoma into the internal auditory canal (IAC) and cerebellopontine angle (CPA) is presented, which appeared 16 years after primary tumor had been treated by surgery and radiation therapy. The 66-year old patient was considered cured from the primary disease, when she started with a rapidly developing hearing loss and intermittent facial palsy. Magnetic resonance image (MRI) displayed an intra- and extracanalicular tumor mass, which radiologically resembled a vestibular schwannoma. Surgery was performed and histopathological studies showed an adenocarcinoma compatible with breast origin. Metastasis is a rare occurrence within the IAC and CPA. Clinical history of severe facial palsy will rise suspicion of malignant tumor in spite of the radiological findings

ABSTRACT

Oito pacientes com linforma intracraniano maligno primário (LMP) foram tratados no hospital Nordstadt entre 1982 e 1987. Os LMP constituiram 0,65% de todos os 1.236 tumores intracranianos operados no mesmo período. Mulheres foram afetadas mais freqüentemente que homens (6:2) e a média da idade dos pacientes foi de 55 anos. De acordo com a classificaçäo de Kiel para linformas, as classes histológicas predominantes nos 8 casos foram o linfoma linfoblástico e imunoblástico. Estudos imuno-histológicos realizados em 4 casos revelaram a origem tumoral nos linfócitos B. Após cirurgia radical ou subtotal dos tumores, 6 pacientes receberam radioterapia, cujas doses variaram de 30 a 56 Gy. Dois pacientes morreram no período pós-operatório imediato devido a insuficiência cardia-respiratória e hemorragia intrapontina, respectivamente. A autópsia näo revelou sinal algum de envolvimento tumoral fora do sistema nervoso. Dois pacientes ainda vivem, 22 e 54 meses após cirurgia, respectivamente. O tempo de sobrevida média dos 4 casos restantes foi de 20 meses
