Variable Presentations of Emphysematous Liver Abscesses: Experiences From Four Cases at a Tertiary Care Center.

Emphysematous liver abscesses usually present with fever and abdominal pain with radiological investigations showing air inside the abscess cavity and biochemical parameters suggestive of sepsis. This is a condition that needs urgent intervention, but it can present with variable presentations and the gas under the right dome of the diaphragm makes the diagnosis in dilemma, confusing it with hollow viscous perforation. Hereby we present a case series of variable presentations of emphysematous liver abscesses, successfully managed by timely intervention.

Air embolism during percutaneous nephrolithotomy using air pyelogram during initial access: Does it really occur?

Introduction: In the present era, percutaneous nephrolithotomy (PCNL) is the standard treatment for large (>2 cm) renal or staghorn renal stones. Both air and iodinated contrast has been used to opacify the pelvicalyceal system (PCS) before the dilatation of the tract. There are rare reports of air embolism following air pyelogram on mere presumptions.

Giant cystic pheochromocytoma: A silent entity.

Pheochromocytoma is a catecholamine secreting tumor that originate from chromaffin cells. Usually, it is solid neoplasm of the adrenal medulla, however cystic pheochromocytoma is a rare neuro-endocrine tumour that is frequently asymptomatic and often diagnosed incidentally on imaging or intra-operatively. Only a few cases of cystic pheochromocytomas have been reported in the world literature.
