While Evans, 30, previously assured her fans that the tumors were likely benign, she was still waiting to find out more information from doctors about what exactly was going on.
In an Instagram Story posted to her account on Thursday, March 10, the former MTV personality revealed she finally has a diagnosis.
"I have a diagnosis 💗," Evans wrote alongside a scenic photo without divulging any further details on the matter.
While she has yet to announce what the specific diagnosis is, Evans previously revealed she was undergoing tests for amyotrophic lateral sclerosis, or what is commonly known as ALS.
In a TikTok video shared in late February, Evans explained: "I got a second opinion from a different neurologist and she's going to be checking me for ALS."
"Since she has told me this, yes, I've been freaking out in my head a lot. I've been crying a lot," she admitted. "I've been crying like every single night by myself."
"But we're redoing all my blood work, we're redoing my nerve studies so I have to go get another nerve study next week because that checks for more diseases," the reality star added, while noting the doctor referred her to a neurosurgeon, who is scheduled to examine her in March, about the cysts on her head and spine.
"She's also having me go to a lung doctor because I have a hard time breathing and catching my breath and I'm not sick. Since I have cysts popping up everywhere my doctor wants to check my lungs to make sure they're not there too," Evans added of the next steps she's taking.
"My hands are really shaky and my thumb grip is almost completely gone in my left hand," she shared, before concluding: "Hopefully I'll get an answer soon."
