Diagnosis of Isolated Soft Tissue and Intramuscular Cysticercosis Using High Resolution Ultrasonography
Background: In Cysticercosis, the extraneural tissues are usually involved synchronously or metachronously with the brain. Isolated infestation of soft tissue and muscle in the absence of neural involvement found more commonly than previously known. High resolution ultrasonography has emerged now as an investigation of choice with proven sonological patterns of soft tissue cysticercosis which can entirely negate the need for invasive interventions.
Methods: This Prospective study was conducted on total 6 cases of extraneural cysticercosis over a period of 5 months at Department of Radio diagnosis, Rajshree Medical Institute, Bareilly. HRUSG analysis of 6 cases was done to evaluate and classify the various classic sonomorphological features of isolated cysticercosis involving soft tissue and muscles. FNAC was done only in 2 cases.
Results: Around 6 patients were selected on the basis of inclusion and exclusion criteria. Among 6 cases, 2 were male and 4 were female patients. Two individuals were vegetarian and four were found to be non-vegetarian. Mean age was 39 years. All cases were diagnosed with the help of HRUSG. Intramuscular lesion was identified in 4 cases and 2 cases had subcutaneous involvement with anterior abdominal wall in muscular plane as the commonest site in two patients. FNAC was done in 2 cases confirming the cysticercosis and was treated surgically.
Conclusions: We conclude that with the advent of high resolution ultrasonography and increased clinical awareness of the isolated soft tissue-intramuscular cysticercosis especially in endemic zone, a more conservative non-invasive approach can be applied both in diagnosis and treatment of these isolated cases of cysticercosis.
