• Leg Weakness

  A 28-year-old man with history of anaplastic oligodendroglimoma in the left frontal lobe presented with worsening right leg weakness 2 months after surgical resection. [ncbi.nlm.nih.gov]

  The data showed that for the global EORTC-C30 and BN-20 scores, the physical, emotional function, insomnia, and appetite loss scores were significantly related to disease progression and to seizure and leg weakness, drowsiness and bladder control, motor [dovepress.com]

  In an exploratory analysis, statistically significant worse scores for bladder control, communication deficit, drowsiness, hair loss, motor dysfunction, leg weakness, appetite loss, constipation, nausea/vomiting, pain, and social functioning were observed [cancer.gov]

• Dyslexia

  Alterations Memory Loss Impaired Vision When it appears in the parietal lobe, it often causes: Disturbances in the sense of touch Problems with balance and coordination Inability to maintain concentration and perception of sensory and visual senses Dyslexia [cancerwall.com]

• Seizure

  Antiseizure medicines are given to prevent seizures. They are usually not given unless the tumour has caused seizures. A commonly used antiseizure drug is phenytoin (Dilantin). [cancer.ca]

• Headache

  Fig. 4 A 21-year-old man who had a long history of headache developed a sudden onset hemiplegia. CT scan shows a left frontal hemorrhage, with evidence of calcifications and edema, suggestive of a hemorrhage in a tumor. [neurologic.theclinics.com]

  A case of anaplastic oligodendroglioma with femoral metastasis is presented in a 37-year old male with a 2-year history of progressive headaches and dizziness associated with a 2-month history of epilepsy and right hemiparesis. [ncbi.nlm.nih.gov]

• Personality Change

  The most common symptoms are seizures, headaches, and personality changes. Other symptoms vary by location and size of the tumor. [abta.org]

  Symptoms may include seizures, headaches, and personality changes. Other symptoms may vary depending on the location and size of the tumors including short-term memory loss, visual loss, motor weakness, and language problems. [diseaseinfosearch.org]

• Generalized Seizure

  A 17-year-old woman presented with an anaplastic oligodendroglioma manifesting as generalized seizure. Neuroimaging studies revealed a right frontal tumor. [ncbi.nlm.nih.gov]

  However, the patient didn’t perform any control and presented to our hospital in 2010, July, for a generalized seizure; MRI showed a considerable growth of the previously detected lesion, which presented hyperintense in T2 flair images with some nodular [jneuro.com]

• Papilledema

  The symptoms of increased intracranial pressure, such as headache, visual disturbances, and papilledema, are generally associated with intraventricular lesions. [dovepress.com]

  Among 323 patients from an AFIP series, the most common clinical signs were paralysis (50%), visual loss (49%), papilledema (47%), ataxia (39%), abnormal reflexes (37%), and meningismus (10%) (,6). [pubs.rsna.org]

We hypothesized that chemotherapy would impair HRQOL during treatment but that there would be a similar HRQOL between treatment arms once off treatment. [ncbi.nlm.nih.gov]

Prognosis A prognosis is an estimate of the likely progress of a disease after a diagnosis, based on an average patient group. [braintumour.ca]

Prognosis Prognosis for oligodendroglioma tumors may depend on the grading scale the tumor is in. Patients diagnosed and intervened upon earlier have a higher chance of survival. [cancerwall.com]

However, they are associated with a better prognosis and response to multimodality therapy based on specific molecular changes. [ncbi.nlm.nih.gov]

We found that surgical patients had a better prognosis for OS compared to non-surgical (P = 0.006). Furthermore, multivariate Cox regression analysis demonstrated that surgical patients had a better prognosis for OS, even after PSM. (p<0.001). [journals.plos.org]

Etiology The etiology is not known but no hereditary forms of oligodendroglioma have been reported. However, specific genetic characteristics, such as loss of chromosomes 1p and 19q, are observed. [orpha.net]

Epidemiologic data mostly based on previous WHO histologic classifications Incidence rate of 0.11 cases per 100,000 population (Neuro Oncol 2014;Suppl 4:iv1) 0.5% of primary brain tumors, 2.5% of all gliomas Median age at diagnosis of 49 years (approximately [pathologyoutlines.com]

Summary Epidemiology Until now, the incidence of these tumors has been largely underestimated. Oligodendrogliomas may represent up to 30% of all adult gliomas. [orpha.net]

We therefore performed an analysis of AO patients in the population-based Surveillance, Epidemiology, and End Results (SEER) database. [journals.plos.org]

Pathophysiology of the seeding of intracranial tumours via the cerebrospinal fluid is reviewed. [ncbi.nlm.nih.gov]

Pathophysiology Oligodendrogliomas arise in the cerebral hemispheres and are distributed among the frontal, parietal, temporal, and occipital lobe, in approximately a 3:2:2:1 ratio. [emedicine.medscape.com]

All of these pathophysiological mechanisms, in addition to many other general factors, such as stasis, the presence of inflammation, dysproteinemia, infections, and entrapment, contribute to the hypercoagulable state. [dovepress.com]

Prevention Because the cause or causes of oligodenrogliomas are not known, there are no known preventions. Special concerns Repeat surgery may be necessary for oligodendrogliomas because these tumors sometimes redevelop. [encyclopedia.com]
