Figure Legends:
Fig.1: Acute pancreatitis. USG upper abdomen demonstrates heteroechoic echotexture of pancreas (arrows showing head; neck and body of pancreas).
Figure 2: Serum lipase level. X axis: Days of hospital admission; Y axis: Serum lipase level with reagent vitros lipase
Figure. 3: Acute pancreatitis and acute appendicitis. Contrast CT of abdomen:- (a) demonstrates strandings along the uncinate process of pancreas (*) along with fluid collection in peripancreatic and periduodoneal (>> second and third part of duodeneum) region of retroperitoneum. Fluid in pararenal retroperitoneum in right side limited posteriorly by lateralconal fascia (black arrow). (b) Mural stratification of caecum with symmetrical regular circumferental edematous wall. Fluid collection in retroperitoneum is displacing caecum anteriorly. (c,d) demonstrates retrocaecal appendix is distended (11mm) with fluid and with mild enhancing smooth wall and with periappendiceal fluid collection.
Fig. 4: Acute appendicitis. USG of right iliac fossa region shows:- target appearance of fluid filled appendix (>> <<) with periappendiceal free fluid (*) collection and omental thickening (white arrow).
Fig.5: Macroscopic and microscopic features of acute appendicitis with periappendiceal acute inflammation: (a) Intraoperative image of inflamed Vermiform Appendix. (b) Inflamed Vermiform Appendix measures 7cm x 1.5cm. (c) Muscularis propria layer showing moderate to dense neutrophilic infiltration H & E stain (d) Spared lumen of Appendix showing no neutrophilic infiltration H & E stain (e) Neutrophilic infiltration seen in mesoappendix H & E stain
