RESUMO

BACKGROUND: Chordomas are rare slowly growing tumors that originate from remnants of the notochord. They have a malignant local behavior, causing symptoms due to bone infiltration and compression of neurovascular structures. Only a few cases of brain tumors associated with pathological laughter have been reported in the literature. CASE DESCRIPTION: We report a case of a 42-year-old male patient with this atypical clinical presentation treated at our institution, and discuss the concerning literature. CONCLUSION: Although being a very rare presentation of chordomas, pathological laughter is usually expected to improve after brain stem decompression.

RESUMO

The purpose of the present clinical case is to remind clinicians that craniopharyngiomas, which are benign neoplasms with a high incidence of local recurrences, may also present ectopic recurrences which may at first go unsuspected. These tumors most commonly arise in the suprasellar region and despite their benign histology, they may infiltrate the surrounding neurovascular structures making total removal challenging. Ectopic recurrences of craniopharyngiomas are very rare. We describe an adult patient with ectopic recurrence of craniopharyngioma, emphasizing unique features of the case presentation and its physiopathological aspects. A 49-year-old male presented with headache and visual field defect and was diagnosed with a suprasellar tumor. He was submitted to neurosurgery and histological examination revealed an adamantinomatous craniopharyngioma. Postoperative magnetic resonance imaging (MRI) showed complete tumor resection. The patient remained asymptomatic with no imaging signs of local recurrence during follow up. Five years after surgery, the patient noticed a rapidly growing lump at the surgical incision site. He reported a mild to moderate local trauma 4 months before. A MRI showed a subgaleal cystic tumor arising in the pathway of the craniotomy. Surgical resection of that cystic lesion was performed and histological examination revealed an adamantinomatous craniopharyngioma. One year later no recurrences have been detected. The case reported has two particular features: the local trauma as a potential trigger for tumor progression and the rapidly growing pattern of the ectopic recurrent tumor. We emphasize that although ectopic recurrences of craniopharyngiomas are rare, they may occur away from the primary tumor and quite late in the follow up of the patient.

RESUMO

OBJECTIVE: Primary central nervous system germ cell tumors are rare neoplasms usually located in the pineal and/or suprasellar region. Pure germinomas do not usually secrete beta-human chorionic gonadotropin hormone (beta-HCG) or alpha-fetoprotein (AFP) and diagnosis is made a few weeks or months after beginning of symptoms. CASE: Here we report a case of a pure germinoma in a 20 year-old woman presenting as a sellar mass with suprasellar extension, abnormal serum beta-HCG and a long history of polyuria and polydipsia (4 years), that was initially diagnosed as a pituitary macroadenoma. CONCLUSION: This presentation highlights the importance of thinking in alternative diagnosis to pituitary adenoma when diabetes insipidus is the initial symptom.

RESUMO

In the treatment of complex paraclinoidal and giant cavernous aneurysms, preservation of the patency of the internal carotid artery (ICA) is not always possible, and therapeutic occlusion of the carotid is still an important option for their management. A complete preoperative evaluation of the carotid reserve circulation, including the use of temporary balloon occlusion test and single photon emission computerized tomography (SPECT) should be included in the current paradigms of paraclinoidal and intracavernous aneurysms management. We present a series of fifteen patients with sixteen giant or complex carotid cavernous or ophthalmic aneurysms that were treated following a protocol for our preoperative decision-making analysis. Extracranial to intracranial saphenous vein bypass was reserved to the cases where carotid occlusion would be associated with high risk of ischemic complications and was performed in three patients. Besides the difficulties in dealing with those complex aneurysms, good clinical outcome was possible in our experience with the designed paradigm.

RESUMO

We present a case of a 46-year old woman with a ventral epidural angiolipoma at the lumbosacral level with erosion of the sacrum. About ninety cases of spinal angiolipomas have been previously described in the literature, most of them situated on the thoracic region, dorsal to the dural sac. Angiolipomas can be radically excised with a good prognosis even in the presence of bone erosion. We did not find any other angiolipoma at the sacral level surgically explored in the review of the literature.
