Hydatid Cyst in the Hand

A 52-year-old man presented with a 1-year history of limitation in the movement of his left hand and numbness involving the fingers. The physical examination of his hand revealed swelling, 4th and 5th finger loss of feeling, positive Tinel’s sign, and mildly painful movement with minimal limitation, especially in the 4th and 5th fingers. A radiological examination revealed soft tissue swelling of the hand with no bone erosion or calcification (Figure 1). Magnetic resonance imaging of the patient’s hand revealed multiple, round, multivesicular daughter cysts occupying almost the entire volume of the mother cyst confined to the soft tissues at the flexor surface surrounding the all-flexor tendons and muscles of the hand, with no infiltration into the bone or the surrounding neurovascular structures (Figure 2). Following the irrigation of the cystic cavity with a chlorhexidine solution, the cystic mass was wholly excised with its capsule (Figure 3). The multiple daughter cysts were filled with a muddy substance, typical of hydatid disease. Histopathological examination confirmed the diagnosis of hydatid disease. The patient received 6 weeks of oral albendazole at 400 mg daily. Pericystectomy combined with neoadjuvant therapy can help reduce the complications and recurrence in soft tissue hydatid cysts11.
