This case reports a 53-year-old Caucasian female previously diagnosed with viral encephalitis and Fahr's Syndrome who presented with altered mental status. Shortly after arrival, she displayed severe lactic acidosis and was transferred to the intensive care unit (ICU), where she had a brief seizure. Neurological workup was performed including carotid ultrasound, magnetic resonance angiography (MRA) brain, and computed tomography (CT) angiogram of the neck, all of which were unremarkable. Initial magnetic resonance imaging (MRI) performed showed small, acute ischemic foci in the bilateral occipital lobes and medial left thalamus. Subsequent diffusion-weighted imaging (DWI) MRI of the bilateral occipital lobes showed vasogenic edema, a common finding in Mitochondrial Encephalopathy, Lactic Acid, and Stroke-like episodes (MELAS). The patient was given Levetiracetam and managed supportively. She was progressively extubated and her seizure symptoms and lactic acidosis resolved. Our case represents a unique case in which a patient with non-contributory family history is first diagnosed with MELAS after age 40 after her symptoms were initially attributed to other pathologies.

Tuberculosis infection, which is caused by the bacterium Mycobacterium tuberculosis (Mtb), most commonly manifests in patients with respiratory systems. However, it can also colonize other tissues including skeletal. In our case, a 77-year-old Caucasian male presented to the emergency department following a rollover motor vehicle collision with chief complaints of neck and lower back pain. After clinical improvement and a preliminary negative workup, the patient was deemed stable for discharge. Four months later, the patient was subsequently admitted for worsening back pain with workup suspicious for T9 and T10 discitis osteomyelitis and abscess formation on computed tomography (CT). During this admission, spinal Mtb was confirmed by acid-fast stain and real-time polymerase chain reaction of a CT-guided disc space aspirate of a left paraspinal cystic collection at approximately T9-T10. Given these findings, the patient was subsequently put on standard four-drug therapy for Mtb. Our case demonstrates the importance of considering Pott's disease in the diagnosis of lumbar spinal pain, especially in patients living in areas with high international migration and travel.
