Table 2. Clinical features and magnetic resonance imaging findings of the 8 osmotic demyelination syndrome patients (continued).

Patient number	Location of lesion	Lesion morphology	Routine MRI findings	Prognosis
1	Pons, bilateral caudate nucleus head, thalamus	The pons lesions were symmetrical with a butterfly shape, and the bilateral caudate nuclei and thalamus lesions showed a symmetrical strip shape	The pons signal was a symmetrical long T1/ long T2 signal	There was no significant change in the patient’s symptoms
			The thalamus of the bilateral caudate nucleus showed slightly longer T1 and T2 signal, and DWI showed a low signal
2	Pons	Central strip shape	Long T1 and long T2 signal, DWI showed high signal	The patient’s symptoms improved
3	Pons	Symmetrical butterfly wing	Long T1 and long T2 signal, DWI was high signal	The patient did not improve and requested discharge
4	Pons	Asymmetric point sheet	Slightly longer T1 signal and slightly longer T2 signal, DWI showed a low signal	Death
5	Pons, bilateral thalamus, bilateral basal ganglia	The pons lesion was symmetrical with a trident sign and demonstrated symmetric signals within the caudate heads, lentiform nuclei, medial thalami	Slightly longer T1, slightly longer T2 signal, DWI showed a high signal	The patient’s symptoms improved
6	Pons	Symmetrical trident sign	Slightly longer T1 signal and slightly longer T2 signal, DWI showed low signal	The patient’s symptoms improved
7	Pons	Symmetrical trident sign	Slightly shorter, slightly longer T1, slightly longer T2 signal, DWI showed a high signal	The patient did not improve and requested discharge
8	Pons	Symmetrical dot spots	Long T1, slightly longer T2 signal, DWI showed a low signal	Death
