Olivia Anderson10 said:Brain MRI results: Standard three-plane imaging techniques show normal organization of gyri and sulci, with a healthy relationship between gray and white matter. No signs of ischemic lesions or hemorrhage were found in the brain parenchyma. There are no focal expansive processes. FLAIR sequences show no evidence of demyelinating lesions. The ventricular system is appropriately positioned and sized. The optic nerve chiasm, cavernous sinuses, pontocerebellar angles, and craniocervical junction appear morphologically normal. Within the pituitary gland, there is a discrete elevated signal on T1 and T2 sequences, measuring up to 3 mm, which is primarily suspicious for a pituitary adenoma. Endocrine evaluation and a dedicated pituitary MRI are recommended.
Here is the report, vividsailor7. I need your take on this pituitary adenoma. Is it a tumor, and could it be causing my issues? As a reminder, my symptoms involve abnormal, uncontrolled jerking of my body and limbs out of nowhere. Or is this just an incidental finding from the scan, and what does it actually mean for my health?
Hello,
I missed your post. While we wait for vividsailor7—whom you addressed—to weigh in, I’ll offer my own thoughts on these findings (I have reviewed some of your previous inquiries).
Given the symptoms you described in your earlier posts, this MRI finding—which points toward a microadenoma since it's under 10 mm—doesn't strike me as a likely culprit for your symptoms.
That said, one should certainly wait for the follow-up results, both endocrine and radiological, before reaching a final conclusion.
In medical literature, pituitary adenomas are occasionally cited as potential triggers for epileptiform seizures, though this usually involves much larger tumors that press against the temporal lobe. Additionally, larger tumors can "crush" healthy pituitary tissue, leading to hormone deficiencies—including ACTH. This could theoretically cause fluctuations or drops in blood glucose, which might trigger a seizure, but that is typically observed in children rather than adults.
There is another possibility where an adenoma might link to certain types of epileptiform seizures, though this is more speculative and theoretical. In some types of pituitary adenomas, there is an overproduction of a specific hormone called ACTH, which regulates the adrenal glands. This hormone drives cortisol production; if cortisol levels spike, it could theoretically provoke seizures by acting on specific receptors in the brain. One study noted seizures in patients with elevated serum ACTH and high 24-hour urinary cortisol; once those levels were normalized through treatment, the seizures ceased.
However, these are largely speculations and rare individual cases. Generally speaking, I suspect this finding is likely an incidental discovery made while investigating the involuntary movements.
That's all from me for now.
Best regards. 🙂
