Ogilvie's syndrome, or acute colonic pseudo-obstruction (ACPO), is an occasional disorder that occurs in hospitalized patients who have undergone major surgery. It presents with the clinical features of intestinal obstruction without any definitive intrinsic or extrinsic anatomical cause. Without prompt treatment, it can lead to life-threatening complications. The risk factors of this syndrome must be sought to prevent its occurrence. We report a rare case of idiopathic, spontaneous, and non-traumatic Ogilvie's syndrome, with old age as the only present risk factor in our case. To our best knowledge, this is the first-ever case reported in English scientific literature from Pakistan.
