Primary pineal gland malignancies are uncommon and seldom have papillary architecture. We report a case of a 22-year-old male patient who presented with progressive headache, horizontal nystagmus and worsening diplopia. MRI of the brain showed a lesion in the pineal region. The patient was taken for resection of the lesion which was classified as papillary tumor of pineal region (PTPR). Histologically, the neoplasm was cellular, characterized by eosinophilic cells with indistinct borders, large pleomorphic nuclei, numerous apoptotic figures without necrosis or microvascular proliferation. Prominent perivascular pseudorosettes were seen. Diffuse immunoreactivity for cytokeratin 8-18 was noted. Synaptophysin antibody showed membranous and cytoplasmic positivity. Weak staining for GFAP, vimentin, S-100 protein, and neuron specific enolase (NSE) were observed only focally. This is a case report of this rare pineal region neoplasm which only recently has been described as a histopathologic entity. Although the clinicopathological characteristics of this tumor are not entirely understood, a brief review of the literature as well as our contribution suggest an indolent neoplasm with a tendency for local recurrence. Histologically, PTPR demonstrates a unique assortment of epithelial, ependymal, and neuroendocrine features. The differential diagnosis of papillary neoplasms of the pineal region is reviewed.
The definition of an elderly person is debateable; however, age is a recognised negative prognostic factor for outcome after subarachnoid haemmorrhage, and the age cut-off of 60 years is accepted to define a high risk population. The goal of this article is to access the outcome in this precise population of patients that underwent endovascular treatment (EVT) after aneurysm rupture. Forty-two patients (mean age = 70.24) had 40 aneurysms located at the anterior circulation and nine at the posterior circulation. Thirty-seven (87.9%) patients had Fisher III or IV. Forty-six (93.8%) aneurysms were smaller than 15 mm. Twenty-eight (66.7%) patients were in good neurological state on admission (Hunt and Hess I-III) and 14 (33.3%) in poor state. Satisfactory occlusion rate (total occlusion or neck flow) was achieved in 75% of patients. Follow-up was available in 19 (43.18%) out of the 44 aneurysms treated. Aneurysm recanalization was disclosed in three cases. Satisfactory outcome was achieved on: 60.7% of good grades, 21.4% of poor grades, 43.7% of patients with and 57.6% of patents without comorbidites. Fisher grade (P = 0.0346), comorbidities (P = 0.525) and risk factors (P = 0.515) were not associated with clinical outcome. No age cut-off (65,70 and 75) for favourable outcome could be established, P-values were 0.723, 0.741 and 0.738, respectively. Advancing of age was not associated with an increase number of unfavourable outcome (P = 0.125). Poor neurological status on admission was the only variable associated with unfavourable outcome (P = 0.02). Mortality and morbidity rate related to the procedure were 4.8% and 9.5% respectively. Age should not be taken alone for precluding treatment in ruptured aneurysms, EVT can be considered as a first therapeutic option for elderly persons, since an overall favourable outcome could be achieved in most cases, mainly in non-comatose patients.
Hereditary hemorrhagic telangiectasia (HHT, Rendu-Osler-Weber disease) is a vascular disorder with dominant autosomal transmission characterised usually by multiple mucocutaneous and visceral abnormalities. Neurological manifestations due to the primary involvement of spinal cord by vascular malformations are rare. We present a young man with HHT associated with a central nervous system arteriovenous malformation and a giant perimedullary fistula, that was manifested as progressive myelopathy. The diagnosis was made coupling magnetic resonance imaging to selective spinal arteriography. The therapeutic option was endovascular treatment by mechanically detachable coils which resulted in full exclusion of the fistula with full improvement of symptoms. During follow-up a stable clinical and morphological outcome was achieved. Clinical manifestations in HHT, with emphasis on neurological symptoms, are reviewed as well as the therapeutic options to deal with giant perimedullary fistula.
This study reports the anatomical presentation of internal carotid bifurcation aneurysms and the angiographic results of their endovascular treatment. We treated 17 patients with internal carotid bifurcation aneurysms by endovascular treatment using detachable coils. Follow-ups were conducted for three to 30 months. The pre- and postprocedural anatomical features of the aneurysms, procedural complications, and postprocedural angiographic outcomes were evaluated. The aneurysmal necks were located just above the internal carotid artery bifurcation or at the origins of anterior cerebral artery or the middle cerebral artery. Immediate angiography demonstrated complete occlusion, neck remnant, or residual aneurysms. Post-treatment, two aneurysms that were initially residual spontaneously progressed to complete occlusion, and two large aneurysms that initially demonstrated complete occlusion or neck remnants showed coil compaction and recanalization. Procedural complications occurred in two cases. Endovascular treatment is effective for ruptured and unruptured carotid terminal aneurysms with various anatomical features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
