case_images: The symptoms did not resolve, and subsequent magnetic resonance imaging (MRI) showed an elongated tubular, cystic-appearing mass near the fibular neck extending down till the middle third of the leg (Fig. 1).

case_images: The fascia of the posterior compartment was incised, and the peroneal nerve was identified just beneath the cyst (Fig. 2).
case_images: Intraoperative image showing distal excision of the ganglion cyst up to its stalk.

case_images: The cyst was followed distally till its stalk and removed in toto (Fig. 3).
case_images: Intraoperative image showing the proximal dissection of the cyst up to its base from superior tibiofibular joint so as to decrease the chances of reoccurrence.

case_images: It was then explored for its proximal extension and removed, which measured 2.0 cmx2.0 cmx2.0 cm (Fig. 4, 5, 6).The peroneal nerve was inspected and found to be completely intact.

case_images: The specimen was sent for histopathology which confirmed the diagnosis of a ganglion cyst (Fig. 7).
case_images: Clinical image at 6-month follow-up showing complete recovery from foot drop and the patient was able to dorsiflex completely.

case_images: At 6-month follow-up, the patient reported full clinical recovery (Fig. 8), there were no signs of recurrence on ultrasonography (USG) even at 24-month follow-up.
