A suprasellar meningioma with multiple intratumoral cysts in a 6-month-old boy is reported. A review of literature disclosed only 11 cases so far. They showed a characteristic predominance in males and predominance of fibroblastic type on pathological examination. Intratumoral cystes are less common than peritumoral cysts. The various hypothesis regarding cyst formation are discussed.

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.

The cystic lesions of the gastrointestinal (GI) tract demonstrate the various pathologic findings. Some lesions may present a diagnostic challenge because of non-specific imaging features; however, other lesions are easily diagnosed using characteristic radiologic features and anatomic locations. Cystic masses from the GI tract can be divided into several categories: congenital lesions, neoplastic lesions (cystic neoplasms, cystic degeneration of solid neoplasms), and other miscellaneous lesions. In this pictorial review, we describe the pathologic findings of various cystic lesions of the GI tract as well as the radiologic features of GI cystic lesions from several imaging modalities including a barium study, transabdominal ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging.

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.

A 24-year-old lady with recurrent upper abdominal pain, underwent surgery for cholelithiasis based on imaging diagnosis by ultrasound scanning. At laparotomy, the gall bladder could not be found either in its normal or ectopic locations. The diagnosis of agenesis of the gall bladder was confirmed by operative cholangiography. Duplication cysts of the hepatic flexure were discovered in the position normally occupied by the gall bladder. The stony hard faeces in the cysts were probably interpreted as gallstones on ultrasound. This rare condition is discussed and the importance of intraoperative cholangiography is stressed.

Patients with bilateral nasal vestibule area swelling of 1 week, no obvious pain and symptoms of nasal congestion, bilateral nasal vestibule area was highly uplifted, nostril was significantly smaller, both sides existed a palpable 2. 0 cm × 2. 2 cm and 2. 0 cm × 2. 0 cm cystic mass. Ultrasound showed both sides of the nasal bonehad cystic lesions. Sinus CT showed local quasicircular soft tissue shadow at the bottom of bilateral piriform aperture. The postoperative pathology report: the cystiform tissue is covered with squamous epithelium, infiltration of inflammatory cells could be seen and is consistent with the diagnosis of bilateral nasalvestibular cyst.

We report a partial fetus-like structure (homunculus) in benign ovarian mature cystic teratoma removed from a 23-yr-old female. The cyst displayed various tissues derived from the three germ layers. The homunculus had a distinguished fetal cranial structure with one upper extremity. A partially developed osteocartilagenous skeleton was identified in the cranial structure of the homunculus. Intracranial structures such as cerebral cortex, retinal pigment, and leptomeninges were extruded from the partially disrupted calvarium.

OBJECTIVETo analyze the clinical character, diagnosis and treatment of badly necrotic pyogenic infection in cervical part with pneumatosis of vomica.

METHODSThe clinical character, diagnosis and treatment of badly necrotic pyogenic infection in cervical part with pneumatosis of vomica of 46 cases were investigated retrospectively.

RESULTSLateral and bilateral neck infection cases were 38 and 8 respectively. 30 cases formed primary pyogenic infection in cervical part with pneumatosis of vomica, and 16 did from adjacent sites. Besides the characters of the acute infection, gas storage in deep cervical part abscess was notable. CT and B Ultrasonic examination provided useful informations such as sizes, shapes, capacity, extents of abscess and the relationship between the abscess and vessel or vital organ. Diagnosis puncture and germiculture were performed before and after operation. The results showed that 25 of 46 cases were infected by staphylococcus or streptococcus, and 21 cases did by other bacterium. Exploration and drainage treatments were performed. All cases were cured except 2 died.

CONCLUSIONDiagnostic puncture, CT and/or B Ultrasonic examination are essential for diagnosis and presurgical planning. Germiculture provides reliable evidence for finding pathogeny and therapy. The most possibilities of pyogenic infection with pneumatosis of vomica in cervical part are the action of aerogenic bacterium, infection both in cervical part and chest or swallowing movement of pharynx.
