Most of tumours of the foot are tumour-like (synovial cyst, foreign body reactions and epidermal inclusion cyst) or benign conditions (tenosynovial giant cells tumours, planta fibromatosis). Malignant tumours of the soft-tissue and skeleton are very rare in the foot and their diagnosis is often delayed with referral to specialised teams after initial inappropriate procedures or unplanned excisi...

A 59-year-old man with knee arthritis suddenly developed left posterior thigh pain and complete paralysis of his foot. EMG/nerve conduction studies localized the lesion to the distal sciatic nerve in the thigh (absent motor units from the short head of biceps femoris but normal vastus lateralis). Imaging demonstrated an intraneural ganglion cyst in the tibial nerve extending up to the sciatic n...

Thousands of patients receive hyaluronic acid filler injections, and the effects are generally considered acceptable. The acid rarely causes cutaneous reactions, which are only occasionally reported in the literature.The aim of the present work is to analyze a clinical case that has never been reported in the literature to our knowledge. This case is of a 26-year-old woman who presented with a ...

A 51-year-old man with a 1-month history of lower back pain and radiating pain visited to our pain clinic. A magnetic resonance imaging (MRI) scan demonstrated a cyst like mass at the level of the L4-5 interspace and compression of the thecal sac and the nerve root on the right side. We performed percutaneous needle aspiration of the lumbar zygapophyseal joint synovial cyst under fluoroscopic g...

The magnetic resonance imaging (MRI) features of a rheumatoid arthritic geode are presented. Development of such a cyst from before x ray diagnosis to its coalescence with the wrist joint is described. The evidence suggests that these juxta-articular cysts are not merely an intrusion of the synovial cavity into the bone marrow but start as isolated structures beneath the subchondral bone.

Spinal cord compressing syndrome due to synovial cyst (SC) of the thoracic spine is a rare clinic condition. We report a case of SC located in the thoracic spine causing spastic paraparesis in a 14 year-old female patient. The SC was removed thoroughly by laminectomy. The patient had an excellent recovery. The etiological and therapeutic aspects are discussed.

Although acromioclavicular (AC) joint cysts are infrequent, when they do occur they are typically associated with full-thickness rotator cuff tears or AC joint degeneration, or both. AC joint cysts are also typically benign, being either ganglionic or synovial. Few reports have described the surgical management of massive AC ganglionic cysts. Some of these reports have advocated repairing the u...

Three Chinese patients suffered from severe lumbar spinal stenosis with debilitating symptoms due to a rare condition of ligamentum flavum cysts in the midline of the lumbar spine. This disease is distinct from synovial cyst of the facet joints or ganglion cysts, both intraoperatively and histopathologically. Magnetic Resonance imaging features of the ligamentum flavum cyst are also demonstrate...

We present a case of Guyon's canal syndrome caused by a synovial cyst within the left wrist of a 48-year-old female patient. The patient presented pain and paresthesia in the region of the ulnar nerve, with loss of muscle strength and left-hand deformity. Electroneuromyography showed a compression of the ulnar nerve at the wrist level. Surgical decompression of the nerve at Guyon's canal with r...

The arthroscopic resection of synovial cysts of the wrist is a simple technique which is comfortable for the patient. We report on a series of 96 patients with dorsal synovial cysts (75 women, 21 men). All patients had undergone preliminary treatment which had been unsuccessful. We operated on 32 patients with a volar cyst (27 women, five men). All the patients were operated on as outpatients u...
