Early diagnosis of spinal—epidural metastasis by magnetic resonance imaging

Abstract Background Early diagnosis of meningitis with magnetic resonance imaging (MRI) would be useful for appropriate and effective management, decrease morbidity and mortality, and provide better diagnosis and treatment. The objective of the current study is to compare the accuracy of contrast-enhanced FLAIR (CE-FLAIR) and contrast-enhanced T1WI (CE-T1WI) in the detection of meningeal abnormalities in suspected cases of meningitis. Results Out of 45 patients, 37 patients were confirmed to have meningitis on CSF analysis. Out of the 37 patients, 34 patients were positive on CE-FLAIR sequence and 27 were positive on CE-T1WI. The sensitivity of CE-FLAIR sequence was 91.9% and specificity 100%, while the sensitivity of CE-T1WI sequence was 73% and specificity 100%. Conclusion CE-FLAIR is more sensitive than CE-T1WI in diagnosis of meningitis. It is recommended to be used in any cases with clinically suspected meningitis.

Spinal Epidural

Spinal epidural hematomas (SEHs) are uncommon complications caused by traumatic injuries to the spine. Emergency surgical evacuation is the standard treatment. Although recognized in the literature, the possibility of nonsurgical treatment of traumatic SEHs is far from being codified. The authors report on the treatment of four patients whose traumatic SEHs were diagnosed by magnetic resonance (MRI) imaging and managed conservatively with excellent results. All patients had suffered severe spine injury with fracture of a lumbar vertebral body, were admitted within 12 hours of trauma, and exhibited only minimal neurological disturbances on admission. Magnetic resonance imaging studies were performed within 24 hours of trauma. Hematomas appeared isointense/slightly hyperintense on T1- and heterogeneous on T2-weighted MR images. Clot thickness varied between 0.8 cm and 1 cm, width between 1 cm and 1.8 cm, and length between 2.7 and 9 cm. In light of each patient's fairly good neurological condition a conservative approach was taken. In all cases serial MR imaging documented progressive clot resolution, which was completed within 8 to 10 days of trauma. At discharge all patients were neurologically intact. The conservative treatment option of traumatic SEH should be reserved for exceptional cases whose deficits are minimal, when neurological deterioration is followed by early and sustained spontaneous recovery, and when there are clear medical contraindications for surgery. The results of the present study confirm that nonsurgical treatment is feasible in a subgroup of minimally symptomatic patients who harbor moderate-sized SEHs. Although the authors' experience shows a good spontaneous outcome of some traumatic SEH, further studies are necessary to understand the real spectrum of nonsurgical treatment of such lesions.

Introduction. Musculoskeletal pain (MSP) — has now assumed the character of a non-infectious epidemic and ranks second among the causes of disability, leading to a significant loss of productivity among the working-age population in all industrialized countries. Spondyloarthrosis of the lumbar region and gonarthrosis are the main diseases that doctors face at outpatient appointments. The pathogenesis of the disease develops according to one scenario, accompanied by aseptic inflammation, involvement of the muscular and ligamentous apparatus in the process, leading to the formation of dissimilar locomotor disorders, antinociceptive insufficiency, peripheral and central sensitization. Presents the results of magnetic resonance imaging (MRI), which can be used for early diagnosis of MSD, as well as dynamic control during treatment. Aim — to assess of neuroimaging signs in patients with spondyloarthrosis and gonarthrosis, depending on the genesis of the disease. Methods. An analytical single-stage study was performed with 123 patients with an established clinical diagnosis of MSP, who were divided into four groups: primary gonarthrosis (36 people), post-traumatic (38 people), spondylogenic (30 people) and x-ray negative (19 people). To study neuroimaging signs, MRI was performed on the devices «OPENMARK 4000» 0.42 T of the company «ANKE», «OPART» 0.35 T of the company «TOSHIBA» and «Superstar» 0.35 T of the company «Neusoft medikal systems» in transversal, sagittal and coronary projections, in T1W, T2W and STIR modes with adipose tissue suppression. Results. During MRI examination, 47.2 % of patients revealed spondyloarthrosis of the III grade, 30,1 % — II grade. 33,3 % had damage in the form of fragmentation of the internal and external meniscus of the knee joint, 30.1 % of cases revealed damage to the internal meniscus in the form of longitudinal splitting and the same number of osteophytes. The most common cases were intervertebral disc sequestration (2,4 %) and expansion of the articular gap of the knee joint (4,1 %), and spondyloarthritis of the I grade (7,3 %). When compared in groups, more pronounced neuroimaging signs were detected in posttraumatic and primary gonarthrosis, and they were significantly lower in spondylogenic genesis. When examining the spine, no differences were found in the groups. Conclusion. The study showed high information content of MRI in CA and GA, which allows for early diagnosis of the disease and differential diagnosis.

Transrectal Biopsy

Multi-parameter magnetic resonance imaging has been widely used in the diagnosis and evaluation of prostate cancer, and has important guiding significance for clinical diagnosis of prostate cancer and their treatment. This article studies the value of transrectal multiparametric ultrasound (mpUSS) in the diagnosis of clinically meaningful prostate cancer. 102 patients with high risk factors for prostate cancer were examined by mpUSS and mpMRI. The transrectal biopsy (SB) results of the prostate system were regarded as the excellent standard, and the diagnostic value of mpUSS, mpMRl and mpUSS combined with mpMRl examination for clinically meaningful prostate cancer was analyzed. The results showed that 58 of the 102 patients with SB were diagnosed with prostate cancer. Among them, 43 cases were detected by mpUSS, 50 cases were detected by mpMRl, 42 cases were detected by mpUSS combined with mpMRI (series), and 56 cases were detected by mpUSS combined with mpMRl (parallel). Grouped by Gleason score, the detection rate of mpUSS for clinically significant prostate cancer was 83.74%, and the detection rate of mpMRl was 93.5%. The comparison between the two was not statistically significant (P > 0.05), but when the two inspection methods were combined. The detection rate was 97.8%, which was significantly higher than the two inspection methods alone. Therefore, we conclude that mpUSS can be used as an imaging test for the diagnosis of prostate cancer. In addition, mpUSS has a high application value in the diagnosis of prostate cancer. The detection rate of mpUSS combined with mpMRl examination for clinically meaningful prostate cancer is significantly higher than that of mpMRl examination alone, which can be used as a diagnostic technique for early diagnosis of meaningful prostate cancer and can be used as a guide clinicians’ early diagnosis and treatment of meaningful prostate cancer.

Progressive Paraparesis

Background: Pure epidural spinal cavernous hemangiomas (SCH) account for only 4% of all spinal epidural lesions. Our literature review identified 61 publications reporting on, a total of 175 cases in the magnetic resonance imaging era. Here, we reviewed those cases, and have added our case of what appeared to be a multifocal SCH. Case Description: A 72-year-old male presented with a progressive paraparesis attributed to a T5/T6 dorsolateral extradural mass extending into the right T5/6 foramen. Surgical excision documented the lesion, histologically, was a SCH. A second similar lesion was noted involving the left C7/T1 foramen; as the patient was asymptomatic from this lesion, and no additional biopsy was performed. The patient returned to normal neurological function within 2 months postoperatively. Conclusions: Here, a 72-year-old male presented with a pathologically confirmed T5/T6 epidural SCH and a secondary C7/T1 foraminal lesion suspected to represent a secondary focus of an epidural SCH.
