Chronic encapsulated intracerebral hematoma is a rare pathology which may present after spontaneous intracerebral hemorrhage (ICH) or radiosurgery for arteriovenous malformations. A 66-year-old male presented with recent diagnosis of cerebrovascular accident (CVA) status post-treatment with tissue plasminogen activator and mechanical thrombectomy. His recent diagnoses included infective endocarditis, septic bacteremia, meningitis, and aspiration pneumonia. One month following his CVA, the patient presented with delayed altered mental status. In the setting of increasing lethargy, computed tomography and magnetic resonance imaging of the brain were performed, which suggested a brain abscess, septic emboli, and ventriculitis. The patient was taken to surgery emergently. Intraoperatively, the patient was found to have an encapsulated mass of liquid consistency. Tissue pathology demonstrated ischemic cortical tissue and hemorrhage. Multiple cultures were negative for growth. The patient was ultimately determined to have an encapsulated intracerebral hematoma. Encapsulated intracerebral hematoma should be a part of the differential diagnosis when presented with a brain abscess in the setting of a patient who is at risk of ICH.
BACKGROUND Ehlers-Danlos syndrome (EDS) and its connective tissue laxity often result in high-grade lumbosacral spondylolisthesis. Patients present with debilitating symptoms and neurological deficits. Reports of surgical techniques in non-EDS patients for the treatment of high-grade lumbosacral spondylolisthesis mainly described an open approach, multilevel fusions, and multiple stages with different circumferential approaches. Sagittal adjusting screws (SASs) can be used in a minimally invasive (MI) fashion, allowing intraoperative reduction. OBSERVATIONS A 17-year-old female with EDS presented to the authors’ institute with severe lower back and left L5 radicular pain in 2017. She presented with a left foot drop and difficulty ambulating. Magnetic resonance imaging showed grade IV L5–S1 spondylolisthesis. She underwent lumbar fusion for intractable back pain with radiculopathy. Intraoperatively, percutaneous SASs and extension towers were used to distract the L5–S1 disc space and reduce the spondylolisthesis. MI transforaminal lumbar interbody fusion was completed with significant symptomatic relief postoperatively. The patient was discharged to home 3 days postoperatively. Routine follow-up visits up to 3 years later demonstrated solid fusion radiographically and favorable patient-reported outcomes. LESSONS The authors used SASs in a MI approach to successfully correct and stabilize grade IV spondylolisthesis in an EDS patient with a favorable long-term patient-reported outcome.
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.
