Combined use of maxillomandibular swing approach and neurosurgical ultrasonic aspirator in the management of extensive clival chordoma: A case report

<p>Abstract</p> <p>Introduction</p> <p>Chordoma is a rare malignant tumour with an incidence of metastasis of less than 10 percent. Usually arising from clivus its posterior extension may involve the brainstem before presenting as nasal mass and obstruction. Surgery is the main mode of treatment with adjuvant radiotherapy. However surgery is rarely possible for a large intracranial lesion.</p> <p>Case presentation</p> <p>We report the case of an adolescent patient with a chordoma extending posteriorly to the brainstem and anteriorly to the nasopharynx and managed by the combination of resection using a maxillomandibular swing approach and the use of a neurosurgical ultrasonic aspirator.</p> <p>Conclusion</p> <p>Maxillomandibular swing approach provides good access for large nasopharyngeal tumour extending brainstem area.</p

Clival chordoma with an atypical presentation: a case report.

INTRODUCTION: Clival chordomas present with headache, commonly VI cranial nerve palsy or sometimes with lower cranial nerve involvement. Very rarely, they present with cerebrospinal fluid rhinorrhoea due to an underlying chordoma-induced skull base erosion. CASE PRESENTATION: A 60-year old Caucasian woman presented with meningitis secondary to cerebrospinal fluid rhinorrhoea. At first, radiological imaging did not reveal a tumoral condition, though intraoperative exploration and tissue histology revealed a chordoma which eroded her clivus and had a transdural extension. CONCLUSION: Patients who present with meningitis and cerebrospinal fluid rhinorrhoea could have an underlying erosive lesion which can sometimes be missed on initial radiological examination. Surgical exploration allows collecting suspicious tissue for histological diagnosis which is important for the actual treatment. A revision endoscopic excision of a clival chordoma is challenging and has been highlighted in this report

Displasia fibrosa do clivus: relato de caso Fibrous dysplasia of the clivus: case report

Relatamos o caso de uma paciente de 43 anos com história de cefaléia crônica e diplopia. O exame neurorradiológico demonstrou aumento de volume e alteração na densidade óssea do clivus. Foi submetida a cirurgia e o exame anatomopatológico evidenciou displasia fibrosa. Foram relatados na literatura outros 14 casos de displasia fibrosa envolvendo o clivus. Discutimos essa rara apresentação da doença segundo o quadro clínico, exames de imagem, histologia e tratamento.<br>We describe the case of a 43 year-old woman with chronic headache and diplopia. The neurorradiologic exam showed volume increase and alteration in the bone density of the clivus. She was submitted to surgery and the anatomopathologic evidenced fibrous dysplasia. Other 14 of about fibrous dysplasia involving the clivus are related in the literature. We discuss clinical aspects, image exams, histology and treatment of this rare presentation of the disease
