Abstract

Aneurysmal bone cyst (ABC) of talus is rare benign, expansile and osteolytic bone growth. Cyst contains bloody fluid lined with variable amount of osteolytic giant cells. This is common in epiphyseal ends of long bone and rare in small bones like talus. Here a 20 years’ male with aneurysmal bone cyst of talus managed with wide intralesional curettage with autologous bone graft mixed with synthetic bone graft been presented.

Highlights

Aneurysmal bone cyst (ABC) is destructive tumor-like benign, expansile, and osteolytic bone growth with cyst filled of blood and is rare and unusual in bone like talus.[1,2]
We present a 20 years’ male having ABC of talus managed with wide intralesional curettage and autologous bone graft mixed with synthetic bone graft to fill the wide cavity
For further evaluation, we plan to go for computed tomography (CT) scan to define the lesion

Summary

Introduction

Aneurysmal bone cyst (ABC) is destructive tumor-like benign, expansile, and osteolytic bone growth with cyst filled of blood and is rare and unusual in bone like talus.[1,2] ABCs occur in the metaphysis of long bones though can occur in any bones, rarely occur in feet bones. Distal neurovascular examination, and other locoregional examinations and laboratory parameter were within normal range His X-ray of the left ankle joint [Figure 1(a)] revealed lytic lesion of the talus with some sclerotic changes with normal joint space. For further evaluation, we plan to go for computed tomography (CT) scan to define the lesion His CT scan the left ankle [Figures 1(b-d)] revealed expanding lytic lesion of the talus involving dome, mid and posterior portion with cortical breach measuring 44*41 mm in size with intact ankle joint. Later, he was called on the 6th week postoperatively, 3rd month, 6th month, and 1-year follow-up during which period his pain and discomfort and simple X-ray were [Figures 3 and 4] taken to evaluate graft uptake His VAS score was 1/10 in the 3rd month, 0/10 thereafter. Before going to definitive management, we plan to go for biopsy of the lesion and histopathological examination (HPE)
