Schwannoma of the abdominal wall - diagnostic chalenge

Introduction. Schwannoma or neurilemmoma is a benign tumor of the nerve sheath originating from Schwann cells. Localization in abdominal wall rare. Schwannomas usually manifest themselves as slow-growing asymptomatic tumors. Symptomatology depends on location, involved and size tumor. Case report. We present 43-year-old female patient with schwannoma localized right hypochondriac region. Diagnostic procedures included ultra-sound color Doppler (US), high-resolution magnetic resonance imaging (MRI), histopathological examinations (HP). US showed solid, well-circumscribed mass, whorled, echogenic internal architecture anterior wall. MRI revealed an oval, well-circumscribed, heterogeneous, 3 ? 2.5 centimeters large fusiform mass. T1- weighted presented low signal intensity, while T2- image heterogeneously high intensity. The lesion was completely removed. After pathohistological analysis standard immunohistochemical methods coloring, diagnosis confirmed. Conclusion. tumor, which often without clinical manifestations, may cause delay treatment. Clinical presentation indolent non-specific. Diagnosis this requires multidisciplinary interdisciplinary approach. MR useful highly specific method for verification peripheral A HP confirmed definitive lesion.
