This case report describes a rare occurrence of nephrogenic diabetes insipidus (NDI) in a 45-year-old male with grade IV astrocytoma undergoing TMZ therapy. Following TMZ discontinuation due to haematological toxicity, the patient developed significant polyuria and hypernatremia. Central diabetes insipidus was initially suspected, but limited improvement with desmopressin and normal endocrine investigations suggested renal involvement. The diagnosis of partial NDI was made and linked to TMZ-induced acute tubulointerstitial nephropathy (ATN). Despite symptom onset coinciding with TMZ administration, recovery was delayed after discontinuation, implicating possible lasting tubular damage. Although the precise pathogenesis remains uncertain, it may involve TMZ-induced renal tubule inflammation, affecting aquaporin-2 expression and water retention. In this case, management of NDI included adequate intravenous hydration, oral fluid restriction, and progressive resolution of polyuria without the need for diuretic or non-steroidal anti-inflammatory drug.
