Clinicoradiological features of probable chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) syndrome.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described chronic inflammatory central nervous system disease. This case report describes a young female patient presenting with weakness in bilateral upper and lower limbs and tinnitus for 2 months. A neurological examination revealed signs of brainstem and cerebellar involvement. MRI brain showed characteristic features of CLIPPERS, with punctate and nodular enhancement in the pons and cerebellum. Differential diagnoses were systematically considered and excluded. The patient showed significant clinical and radiological improvement with steroid therapy. No clinical or radiological red flags occurred during the follow-up. This case underscores the critical role of integrating clinical and radiological findings to effectively diagnose and manage CLIPPERS. It emphasises the importance of ruling out alternative diagnoses through a thorough evaluation.

MRI brain findings of Abamectin toxic encephalopathy: a case report with review of literature.

Abamectin is an insecticidal/miticidal compound derived from the soil bacterium "Streptomyces avermitilis". Abamectin toxicity in humans is very rare. We present a case of acute neurotoxicity induced by Abamectin, showcasing distinctive MRI brain findings in a 33-year-old female who exhibited a favourable recovery with the aid of supportive care. In a patient with known exposure to toxins, even with a lack of knowledge of the specific type or class of toxin, recognition of anatomical distribution of lesions on brain MRI and their characteristic appearance can help exclude other causes of neurologic impairment and aid in timely management.
