A 39-year-old man presented with recurrent lower back and leg pain for 8 months due to repeated hemorrhage into an L5 ligamentum flavum cyst. Lumbar MR imaging showed an extradural cystic mass originating from the ligamentum flavum on the right side in the L5 segment. Microsurgical laminotomy and flavectomy were performed. The symptoms resolved completely and the patient had an uneventful postoperative recovery.

Choroid plexus cysts (CPCs) are the most commom neuroepithelial cysts, occuring in more than 50% of some autopsy series. They are typically small and asymptomatic and are discovered incidentally in older patients, usually in the trigone of the lateral ventricle. Symptomatic CPCs (usually exceptionally large, 2-8 cm) are rare. The authors report a case of large symptomatic choroid plexus cyst, located in the trigone of the right lateral ventricle in a 26-yr-old man who presented with headache and vomiting. The patient underwent endoscopic removal through a burr hole placed 3 cm from the midline and just behind the hair line. The histological examination of the cyst wall was consistent with choroid epithelium. Despite of postoperative intraventricular hemorrhage and catheter infection, he discharged home without neurologic deficits. The endoscopic fenestration rather than excision should be considered as the first surgical procedure because the goal of treatment is shrinkage of the cyst until normal cerebrospinal fluid flow is restored.

Aneurysmal bone cyst of mastoid bone is seldom, here one case was reported. The mastoid bone of the patient presented with a baloon-like swelling full of non-coagulated blood and serous-hemorrhagic fluid. CT scan demonstrated a large expansile destructive mass located in left mastoid bone region with the thin or absent cortical bone. The MRI demonstrated T2-weighted images and clear boudary from surrounding tissue. Pathologic reported that the mastoid bone was repalcement with lacunar divided by fibro-tissue, containing numerous hemosiderin, giant cells and inflammatory cells. A surgery was performed and the patient was cured.

Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. We report a case of a 42 year-old, right-handed female, who presented with pain of the right wrist following a fall on the palm of the hand. Clinical study revealed a moderate swelling over the mid-section of the palmar face and pain through extreme ranges of motion of the wrist. Plain radiographs and CT-scan of the wrist have revealed an intraosseous ganglion cyst of the lunate bone. Curetting-filling by Kuhlman's vascularized radial bone graft allowed a good functional recovery. The clinical, radiological and therapeutic aspects are discussed.

OBJECTIVE: To study the clinical and pathological characteristics of nonfunctioning parathyroid cysts. METHOD: Six cases of nonfunctioning parathyroid cysts who were hospitalized during 1997-2007 were retrospectively analyzed. The clinical features, serum calcium, B-ultrasonic, CT and nuclide scanning were performed. Postoperative pathologic and immunohistochemistry detection in nonfunctioning parathyroid cysts were made. RESULT: Tumors in the 6 cases were underwent surgical ablation and diagnosis was verified by pathology. CgA (chromogranin A), Syn (synaptophysin), NSE (and neuron specific enolase) expressions were positive. Follow-up six months and five years after operation, there is no recurrence. CONCLUSION Surgical resection is most effective in treating nonfunctioning parathyroid cysts and diagnosis is made by pathologic examination.

We experienced a case of a tracheoesophageal cyst in the posterior mediastinum of a three-year-old girl, who complained of cough and fever. We confirmed this case by computerized tomography and pathologic examination after surgical resection. A brief review of the literature is presented.
