Objective Reversible splenial lesion syndrome (RESLES) is a clinical radiological syndrome characterized by a reversible lesion of the splenium of the corpus callosum with a decreased apparent diffusion coefficient (ADC) value. The clinical manifestations of RESLES are diverse. Methods Fifteen cases of adult RESLES patients (10 males and 5 females) were retrospectively selected from the radiology system using the key word "corpus callosum" at a university-affiliated tertiary care hospital between May 1, 2015 and December 31, 2019. The possible precipitating factors, clinicoradiological findings and modified Rankin Scale (mRS) on follow-up were then analyzed. Results The patient ages ranged from 22 to 53 years old. The mean age was 34 years old. The most common neurological symptoms included headache (3/15), dizziness (3/15), first onset of seizure (3/15), paroxysmal blurred vision (2/15), vertigo (2/15), amnesia (2/15), and confused consciousness without seizure (2/15), followed by drowsiness (1/15), paresthesia (1/15), dysmetria (1/15) and dysarthria (1/15). The precipitating factors included infection, seizure, anti-epileptic treatment with levetiracetam, carbamazepine, valproate, hyperglycemia, hypoglycemia, cerebral venous sinus thrombosis, and rabies vaccine injection prior to the onset of RESLES. All cases were carefully followed up and had excellent prognoses. Conclusion RESLES manifests as variety of symptoms with less specificity and precipitating factors. Paroxysmal blurred vision may be a relatively specific symptom of RESLES. Levetiracetam, carbamazepine or valproate could be the cause of RESLES, exposure to the rabies vaccine could be another predisposing factors for RESLES as well. RESLES type 1 was therefore found to be highly "reversible" with an excellent prognosis.

BACKGROUND Levetiracetam (LEV) is an anticonvulsant commonly used for treatment of generalized and partial seizure disorder. Some of the common side effects associated with levetiracetam include somnolence, dizziness, headaches, and mood changes. Rhabdomyolysis and increase in creatine kinase (CK) levels is one of the rarely reported effects of LEV. CASE REPORT We report a case of a 22-year-old man admitted for evaluation of new-onset generalized tonic-clonic seizures. The patient was started on levetiracetam 500 mg twice a day, after which his CK levels started to increase, with maximum level of 21 936 IU/L noted on day 5. No improvement in CK levels was observed even with aggressive intravenous hydration. In the absence of any other obvious cause, the persistent elevation in patient's CK levels was suspected to be due to LEV. Our suspicion was supported by significant decrease in CK levels (from 21 936 IU/L to 11 337 IU/L) after about 30 h of discontinuation of LEV. We reviewed cases of LEV-induced rhabdomyolysis reported in the literature over the last decade and found 13 cases with almost similar correlation between initiation of LEV and increase in CK levels. CONCLUSIONS Our case report stresses the importance of close monitoring of CK levels and kidney functions after initiation of LEV, and to consider changing the anticonvulsant medication if CK levels are noted to be significantly high to avoid kidney injury.
