Abstract
|

Introduction:
Retroperitoneal neurilemmoma is a common tumor in an uncommon place. If secondary changes occur in the tumor, it becomes very difficult to diagnose by clinical and radiological examination. In this case report, we have shown how a neurilemmoma with cystic degeneration was misdiagnosed as hydatid cyst till it was confirmed by histopathology.
Case Report: A 30-year-old female presented with pain on right side of abdomen since one month. Clinical examination revealed firm mass of 8x10 cm in right hypochondriac and lumbar region. Radiological examination showed it as complex cystic lesion with multiple membrane probably hydatid cyst. With preoperative diagnosis as hydatid cyst laparoscopy revealed cystic lesion with degenerated cheesy tissue then by opening the abdomen by sub costal incision deroofing of the cyst was done. Histopathological examination confirmed it as neurilemmoma. Schwannomas have true capsules composed of epineurium. Although target and fascicular signs are characteristic radiological features of schwannoma, these are not frequently seen in retroperitoneal schwannomas. In the absence of typical signs, diagnosing a retroperitoneal schwannoma is difficult when using cross-sectional imaging alone. Conclusion: A retroperitoneal schwannoma is a rare disorder and most cases are benign for which enucleation is curative. Secondary changes can misdiagnose the cases both clinically and radiologically and one should be aware of it. | |
