Dermatofibrosarcoma protuberans (DFSP) is a rare, low-to-intermediate grade locally aggressive sarcoma. It typically arises in the dermis and infiltrates subcutaneous tissue, predominantly of the trunk and extremities. It has a propensity to recur locally. There are infrequent incidences of distant metastases. The purpose of this study was to know about different imaging modalities in the assessment and management of DFSP. A retrospective study was done on a series of four patients who presented to our institute with complaints of progressive swellings in different regions of the body. A clinical diagnosis of soft-tissue sarcoma was made. They underwent radiography/ ultrasonography/computed tomography/magnetic resonance imaging in our department followed by excisional biopsy. There were certain imaging features suggestive of DFSP. On excisional biopsy, all were proven to be DFSP. There was surgical resection in all the reported cases. After 6 months of follow-up, there was local recurrence in two of the cases. We came to the conclusion that, due to the superficial appearance of DFSP, common lesions are initially thought of which leads to misdiagnosis. Imaging techniques are not always utilized and there is a delay in their proper management. Knowledge of the variable imaging appearances of DFSP may help in the diagnosis of difficult and atypical case scenarios and help in proper early management.
Annular pancreas is a rare developmental anomaly. Partial annular pancreas is less known and is very rare. A band of pancreatic tissue continues from the pancreatic head and incompletely encircles the pancreas. This typically gives a “crocodile jaw” configuration. In symptomatic cases patients present mostly in 3rd to 6th decade of their life, with abdominal pain, postprandial fullness, vomiting, upper gastrointestinal bleeding, acute or chronic pancreatitis, and in rare instances, biliary obstruction. The person can also be asymptomatic; in that case it will be an incidental finding. We are presenting a case of partial annular pancreas causing nonspecific symptoms. This was an incidental finding, studied and managed in a tertiary care centre.
Hydatid disease (HD) is a parasitic infection endemic to many regions worldwide. It is commonly seen in persons practicing animal husbandry. The causative organism is Echinococcus granulosus, with the liver being the most common organ involved. Here we are presenting 4 cases of hydatid disease in different organs with ultrasound findings. Familiarity with the variable ultrasonographic appearances of hydatid diseases will provide essential advantages in making the diagnosis and may aid in diagnosing complex or atypical cases. Early imaging diagnosis of HD can significantly improve treatment outcomes, especially in patients living in endemic countries, like India.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
