Solid pseudopapillary neoplasm of the pancreas: CT imaging features and radiologic-pathologic correlation
PURPOSE:We aimed to evaluate the imaging features of solid pseudopapillary neoplasm (SPN) of the pancreas with an emphasis on radiologic-pathologic correlation.METHODS:Ten patients (all female; mean age, 32 years) with histologic or cytologic diagnosis of SPN encountered between January 2007 and December 2013 were included in this study. Preoperative computed tomography (CT) images were reviewed for location, attenuation, enhancement pattern, margin, shape, size, morphology, presence of capsule and calcification. CT appearances were correlated with histopathologic findings. RESULTS:Tumors in the distal pancreatic body and tail had a tendency to be larger (mean size 12.6 cm vs. 4.0 cm). Six of the nine tumors that were resected had a fibrous pseudocapsule at histology, five of which could be identified on CT scan. Eight lesions had mixed hypoenhancing solid components and cystic areas corresponding to tumor necrosis and hemorrhage. The two smallest lesions were purely solid and nonencapsulated. Varied patterns of calcification were seen in four tumors. Three of the four pancreatic tail tumors invaded the spleen. At a median follow-up of 53 months, there was no evidence of recurrence in the nine patients who underwent surgical resection of the tumor.CONCLUSION:A mixed solid and cystic pancreatic mass in a young woman is suggestive of SPN. However, smaller lesions may be completely solid. Splenic invasion can occur in pancreatic tail SPNs; however, in this series it did not adversely affect the long-term outcome
Role of active and passive surveillance in early case detection and prevention of disease spread in COVID-19 pandemic: our experience
Background: Strong surveillance systems which include both active and passive surveillance are the important steps to halt a disease outbreak by early case detection and management, which helps in breaking the chain of transmission. The main aim of this article is to share our experience regarding the active and passive surveillance done during COVID 19 spread in the year 2021.Methods: The early case detection of COVID 19 cases through active and passive surveillance was slightly different from the usual methods that are carried out for regular known communicable diseases. Active surveillance was done round the clock by screening of all vehicles entering the union-territory of Puducherry and by house-to-house survey. Passive surveillance was carried out by screening of various symptomatic patients attending to hospitals which needed motivation of health personnel as well as awareness among the general public.Results: Out of 12 Govt. PHCs (3,30,000population) where active and passive surveillance was conducted, the total number of individuals referred to designated COVID centre by active and passive surveillance is 30 and 110 respectively for COVID testing and further management.Conclusions: Active and Passive surveillance plays a major role in early case detection and prevention of disease spread in COVID-19 pandemic

Imaging of parotid gland primitive neuroectodermal tumor
A seven-years-old boy presented with recurrent episodes of right
parotid gland swelling that was presumptively being treated as
sialoadenitis. Interrogation with ultrasonography, computerized
tomography and magnetic resonance imaging revealed a heterogeneous mass
occupying the right parapharyngeal space, imperceptibly merging with
adjoining parotid gland, scalloping the vertical ramus of the mandible
and involving the base skull with widening of the foramen ovale. The
findings at surgery and histopathology provided a final diagnosis of
parotid gland primitive neuroectodermal tumor. This report emphasizes
on the imaging findings of this rare tumor occurring in such an unusual
location
