The bacterial genus Myroides is a gram negative Bacilli found ubiquitously in nature, isolated from both soil and water bodies. Although uncommon in human microflora, infections with Myroides bacteria have been observed. Due to increasingly advanced technologies in the detection of microorganisms, more number of these infections has been identified. Most cases of Myroides infection appear to occur in immunocompromised patients or patients who have existing comorbidities. So far, the documented infections are soft tissue related, ranging from mild cellulitis to fulminant necrotizing fasciitis. However, cases of endocarditis, bacteremia, UTI, pneumonia, and one case of ventriculitis in an infant due to Myroides bacteria have been reported. Here we present a case of a 52-year-old man presented with increased twitching, muscle spasms and shaking after a fall with head and left foot injury. Physical exam was significant for diffuse tetany, tremors, and chronic stasis dermatitis with a 10 cm × 10 cm ulcerated weeping ulcer on the lateral aspect of the right ankle overlying the lateral malleolus extending to the dorsum of the foot. Magnetic resonance imaging of brain suggested ventriculitis/meningitis with pus in the posterior horn of the ventricles. Blood cultures grew Myroides species. Antibiotic therapy was optimized to Levofloxacin and PiperacillinTazobactam based on sensitivities. There are few cases published on Myroides species related infections, but most were related to cellulitis or diabetic foot ulcer. Our case is unique because the patient is diagnosed with Myroides bacteremia, which is rare presentation, with ventriculitis/ meningitis, an extremely rare phenomenon. Chad
