A consecutive series of 23 patients underwent operative removal of an intramedullary spinal cord ependymoma between January, 1976, and September, 1988. Thirteen women and 10 men between the age of 19 and 70 years experienced symptoms for a mean of 34 months preceding initial diagnosis. Eight patients had undergone treatment prior to tumor recurrence and referral. Mild neurological deficits were present in 22 patients on initial examination. The location of the tumors was predominantly cervical or cervicothoracic. Radiological evaluation revealed a wide spinal cord in all cases. Magnetic resonance (MR) imaging was the single most important radiological procedure. At operation, a complete removal was achieved in all patients. No patient received postoperative radiation therapy. Histological examination revealed a benign ependymoma in all cases. The follow-up period ranged from 6 to 159 months (mean 62 months) with seven patients followed for a minimum of 10 years after surgery. Fourteen patients underwent postoperative MR imaging at intervals ranging from 8 months to 10 years postoperatively. No patient has been lost to follow-up review and there were no deaths. No patient showed definite clinical or radiological evidence of tumor recurrence during the follow-up period. Recent neurological evaluation revealed functional improvement from initial preoperative clinical status in eight patients, no significant change in 12 patients, and deterioration in three patients. The data support the belief that long-term disease-free control of intramedullary spinal ependymomas with acceptable morbidity may be achieved utilizing microsurgical removal alone.
Caution should be exercised while performing any endonasal procedure in the settings of trauma where disruption of the anterior cranial base is possible.
Background: There are currently no clear guidelines for the management and radiological monitoring of pediatric patients with epidural hematomas (EDH). We aim to compare clinical and radiographic characteristics of pediatric EDH patients managed with observation alone versus surgical evacuation and to describe results of repeat head imaging in both groups. Methods: We performed a retrospective observational study of pediatric patients diagnosed with traumatic EDH at a level II trauma center. Results: Forty-seven cases of EDH were analyzed. Sixty-two percent were managed by observation alone. Patients undergoing surgery were more likely to have an altered mental status (17 vs. 72%, p < 0.001), but there were no other significant clinical differences between the groups. The mean initial EDH thickness and volume were 8.0 mm and 8.6 ml in the observed group and 15.5 mm and 35 ml in the surgery group, respectively (p < 0.001 for both comparisons). Eighty-six percent of the observed and all surgery patients underwent repeat CT imaging. The initial repeat CT scan results led to surgery in 1 patient who was initially treated with observation. Conclusions: Most pediatric patients with EDH can be managed with observation. Mental status and radiographic findings should guide the need for surgical intervention. Multiple repeat CT scans have minimal utility in changing management.
The case of a 66-year-old man with a 3-year progressive hearing loss and a homogeneous left cerebellopontine angle mass on magnetic resonance imaging scan is described. At surgery, the major portion of the mass was a typical encapsulated, solid, acoustic schwannoma, but the most rostral portion was a distinct, flaky, cystic mass without a well-defined capsule, typical of an epidermoid cyst. The radiographic and operative findings of this unique coexistence of two different benign cerebellopontine angle masses are presented.
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.
