Diagnosis of Intramuscular Cysticercosis by High-resolution Ultrasonography: A Prospective Hospital Based Study
Background: Cysticercosis is one of the common infectious disease, the extraneural tissues are usually involved synchronously or metachronously with the brain in this disease. Isolated infestation of soft tissue and muscle in the absence of neural involvement is more common than previously known. High resolution ultrasonography has evolved now as an investigation of choice with proven sonological patterns of soft tissue cysticercosis which has reduced the need for invasive interventions. Methods: Prospective evaluation of total 9 cases of extraneural cysticercosis over a period of 6 months at Prakash institute of Medical Sciences and Research. HRUSG analysis of 9 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 3 cases.
Results: Around 9 patients were selected on the basis of inclusion and exclusion criteria. Among 9 cases, 5 were male and 4 were female patients. Three individuals were vegetarian and five were non vegetarian. Mean age was 35 years. All cases were diagnosed on HRUSG. Intramuscular lesion was identified in 7 cases and 2 cases had subcutaneous involvement with anterior abdominal wall in muscular plane as the commonest site in three patients. FNAC was done in 3 cases confirming the cysticercosis and was treated surgically.
Conclusions: 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.
