Computerized Tomography(CT) scan plays an important role in the diagnosis and treatment of sinus and skull base lesions. The CT image distinctly provides detail of bony anatomy, anatomical variation, and the extent of diseases, and differentiates between inflammatory, benign, and malignant sinus and skull base pathology.1 It is an important aspect of imaging that helps not only the diagnostic role but also rules out other sinus pathology and helps in designing the surgical plan by 3D-MPR  and 3D VRT CT scan. Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases. It can be associated with sinusitis. The patient may present either with a unilateral headache that is difficult to differentiate from a migraine or often no symptoms which are diagnosed by chance during a radiological examination. Here we present a case of a 42-year female present with left frontal headache and facial fullness treated with endoscopic and open approaches which were designed by CT paranasal sinus 3-D multiplanar reconstruction(3D-MPR) and from 3-D MPR and volume rendering technique(3D VRT).

A biloma is an encapsulated collection of bile located in the abdomen. It usually occurs spontaneously or can be secondary to traumatic injury (hepatobiliary surgery) and in rare condition it can occur as complication of cholecystitis and cholangiocarcinoma. The diagnosis can be suggested on the basis of patient’s medical history, clinical symptoms and imaging findings but final definitive diagnosis can only be made by aspiration of the content and biochemical analysis. We here report a case of 62 years male patient admitted with acute abdominal pain in the right hypochondrium caused by a spontaneous biloma. We discuss the role of the various diagnostic imaging techniques, particularly which of ultrasound and CT. The biloma was identified on computed tomography in this case.
