Spontaneous rupture of a pyogenic liver abscess is a rare entity reported. Spontaneous cutaneous rupture of a pyogenic liver abscess is even a rarer clinical entity not well documented in the literature. A patient having spontaneous cutaneous rupture of a pyogenic liver abscess is reported. The condition is rare and serious because of the possible delay in diagnosis. Recently, with the advent of ultrasound (USG) and computed tomography (CT) scan, there has been improvement in the rate of early diagnosis of liver abscess as well as in prognosis. The clinical presentation is variable; in some cases there are delays, misdiagnoses, or incidental recovery. Per cutaneous catheter drainage under USG or CT guidance has become the standard of care.

Aim:To evaluate the sensitivity and specificity of noncontrast helical computerized tomography (CT) in ureteric colic with comparative evaluation of KUB and ultrasonography (USG).Setting:Tertiary care university hospital.Materials and Methods:One hundred patients aged between 20 and 75 years referred from the emergency department as acute ureteric colic were evaluated with KUB and USG followed by noncontrast helical CT.Results:Noncontrast helical CT was 91% sensitive and 98% specific in detecting urolithiasis compared to a sensitivity of 20% and 30% for KUB and USG and specificity of 94% and 98% respectively.Conclusion:Noncontrast helical CT is a very sensitive and specific investigation for evaluation of acute flank pain due to urolithiasis, besides helping in the detection of nonrenal causes of pain.
