We describe a rare case of intradural-extramedullary primary spinal cysticercosis. A 42-year-old man visited our institute for lower back pain. He denied having consumed raw meet. Magnetic resonance (MR) images revealed an intradural pure cystic mass at the L3-L4 level. A radiologic diagnosis of spinal arachnoid cyst was established. Three years later, he complained of aggravated back pain, and follow-up MR examination showed a markedly expanded cyst, occupying the subarachnoid space from the T11 to the S1 level. L2 hemilaminectomy was performed, and a yellowish infected cyst bulged out through the dural opening. The cyst was removed en bloc. The histopathological findings of the cyst were consistent with parasitic infection. Serum enzyme-linked immunosorbent assay (ELISA) confirmed the presence of spinal cysticercosis. As there was no intracranial lesion, the final diagnosis was primary spinal cysticercosis, which is very rare. MR imaging is a sensitive diagnostic tool for detecting cystic lesions in the spine; however, it is difficult to distinguish cysticercosis from non-infectious cysts such as an arachnoid cyst without using gadolinium enhancement. Clinicians treating spinal cysts with an unusual clinical course should include cysticercosis as a differential diagnosis. We recommend contrast-enhanced MR imaging and serum ELISA in the diagnostic work-up of such cases.
A myxoma is the most common primary tumor of the heart. It has been reported as the source of a cardiogenic embolism. Therefore, it is important for clinicians to detect the myxoma early via echocardiography to prevent complications, such as syncope, sudden death, and cerebral embolic ischemic stroke. This report presents the case of a 54-year-old female whose clinical manifestation of atrial myxoma was an ischemic stroke. Atrial myxoma was later confirmed as the cause of her symptoms via transesophageal echocardiography.
ObjectiveThe purpose of this study was to evaluate the effect of patients' bod mass index (BMI) on surgical outcomes following one-level lumbar microdiscectomy.MethodsFrom June 2003 to March 2007, 129 patients underwent one-level lumbar microdiscectomy performed at a single institution. We divided the patients into 3 groups, depending on BMI. A retrospective study was conducted among the 3 groups. The operation time, estimated blood loss (EBL), postoperative hospital day, recurrent disc herniation, intraoperative durotomy, and postoperative epidural steroid injection were analyzed. Regression models were used to predict the relationship between BMI and surgical outcomes including operation time and EBL.ResultsAs BMI is greater, as the operation time is longer and the EBL is more. In particular, linear regression model analysis implied that 2.35 minute in the operation time is longer and 8.89cc in EBL is more, as BMI of 1 kg/m2 is increased. No statistically relevant differences were observed for postoperative hospital day, recurrent disc herniation, intraoperative durotomy, and postoperative epidural steroid injection.ConclusionThe operation time and EBL was significantly increased in obesity, but there were no differences in surgical outcomes. Our results demonstrated that higher BMI are not likely to encounter heightened morbidity in lumbar microdiscectomy.
ObjectiveThe authors conducted a retrospective study to compare the implantation of carbon fiber composite frame cages (CFCFCs) to the implantation of polyetheretherketone (PEEK) cages after anterior cervical discectomy for cervical degenerative disc disease. In addition, the predictive factors that influenced fusion or subsidence were investigated.MethodsA total of 58 patients with single-level degenerative disc disease were treated with anterior cervical discectomy and implantation of stand-alone cages; CFCFCs were used in 35 patients, and PEEK cages were used in 23 patients. Preoperative and postoperative radiological and clinical assessments were performed.ResultsDuring the mean follow-up period of 41 months, fusion occurred in 43 patients (74.1%), and subsidence developed in 18 patients (31.0%). Pain decreased in all patients, and the patients' satisfaction rate was 75.9%. Neither fusion nor subsidence was related to the clinical outcome. There were no significant differences in the clinical and radiological outcomes between the CFCFC and the PEEK cage groups. Smoking history (p=0.023) was significantly associated with pseudarthrosis, and cage height (≥7mm) (p=0.037) were significantly associated with subsidence.ConclusionThe clinical and radiological results were similar between the CFCFC and the PEEK cage groups. Fusion or subsidence did not affect the clinical outcomes. Smoking history and cage height (≥7mm) were predictive factors for pseudarthrosis or subsidence in anterior cervical discectomy and fusion with stand-alone cages.
Because candidiasis is usually associated with immunosuppression, candida arthritis in an immunocompetent patient is rare. The symptoms of candidiasis are similar to bacterial infections, tuberculosis, and autoimmune diseases. In our patient with no predisposing factors, candida arthritis was initially excluded because the probability of occurrence was low. The patient had no leukocytosis, the acid-fast bacteria (AFB) stain was negative, and the autoimmune antibody screen was negative. After Candida parapsilosis was cultured in the synovial fluid, the patient was treated with amphotericin B (0.7 mg/kg/day) and oral fluconazole (400 mg/day). The treatment was successful and there were no side effects of the medications.
Background:Since the first report of a rapidly resolved subdural hemorrhage (SDH) in 1986, few additional case reports have been presented in the literature.
Case Report:An 82-year-old female patient presented with a SDH over the left convexity. The SDH was removed via catheter drainage through a burr hole trephination. Post-operative computed tomography (CT) following 300 mL drainage from the chronic SDH demonstrated a newly developed SDH along the right convexity. A follow-up CT performed 2 hours later revealed an unexpected significant resolution of the acute SDH.
Conclusion:The spontaneous resolution of acute SDH is believed to result from redistribution by washout of the hematoma by cerebrospinal fluid dilution. However, its exact pathophysiology is not well understood. When surgical evacuation is considered in acute SDH, conservative management should also be considered because spontaneous resolution of hemorrhage remains a possibility.
