This is a case report of first branchial cleft cyst in 56 year old male patient, which was tentatively diagnosed as acute right submandibular abscess resulted from the periapical lesion of the lower right second molar. The results are as follows, 1. The accompanying ipsilateral inflammatory swelling resulted from the periapical lesion of lower right second molar tooth makes the diagnosis difficult. 2. The onset of this case was very late in comparison to the mean discovering age of branchial cleft cysts. 3. The plain radiography using contrast media is helpful for the diagnosis of cystic lesions within soft tissues. 4. This case in a first branchial cleft cyst(Type I) which occurs less than 1% of all branchial cleft anomalies.

The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

Cholelithiasis and choledolithiasis were diagnosed with serum chemistry, abdominal radiography and ultrasonography in a 2.0 kg, 10 year-old Yorkshire Terrier dog showing signs of anorexia, vomiting, iceterus and depression. In serum chemistry, the level of alanine transferase, alkaline phosphatase, aspartate transferase, total bilitrubin and direct bilirubin were elevated. On abdominal radiographs, focal lesions with increased radiopacity were seen in the hepatic region and the size of liver was increased. In ultrasonographic examination, it were seen that distension of gall bladder, hypercehoic change of liver, obstruction of cystic duct by calcult and calculi in the gall bladder. Cholecystectomy was undertaken and there were no complications after the operation.

Pituitary abscess is a very rare disorder, since antibiotics therapy has become widely available. Clinically and radiologically, the preoperative diagnosis of pituitary abscess is difficult because of its features which may be identical to those of any space-occupying lesions of the sella turcica. A combination of clinical features, such as meningitis, paranasal sinusitis and panhypopituitarism with intrasellar cystic lesion with homogeneous ring enhancement on computed tomography or magnetic resonance image should raise the suspicion of a pituitary abscess. Drainage of the abscess through trans-sphenoidal approach, appropriate antibiotics therapy, endocrine assessment and hormonal replacement should bring complete recovery to the patient. The authors review the literature and report two cases of primary pituitary abscess.

Discal cysts are rare lesions that can cause radiating leg pain. Because they are very rare, their natural history and the details of the therapeutic guidelines for the treatment of these cysts are still unknown. A 30-year-old male patient presented to our institute with radiating pain in his left leg and mild back pain. Magnetic resonance imaging (MRI) revealed an intraspinal extradural cystic mass with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images at the L5-S1 level. The partial hemilaminectomy and cyst resection were performed. We report a patient with low back pain and radiating leg pain caused by a lumbar discal cyst and discuss the treatment of this cyst.

Lumbar discal cyst is a rare cause of radiculopathy. Their exact pathogenesis and the optimal treatment modality remain unidentified. Depending on their location, discal cysts cannot always be easily identified intraoperatively. We describe 2 patients with discal cysts and introduce an intraoperative discography technique for discal cyst location. Both patients were treated with surgical excision; with intraoperative discography, the cystic lesions could easily be detected and removed.

We report a case of primary central nervous system(CNS) lymphoma in an organ recipient. A 33-years-old man who underwent a renal transplantation 3years previously presented with headache and vomiting. In Brain computed tomography scans and magnetic resonance images showed multiple periventricular cystic rim enhancing masses. Pathologic diagnosis by stereotactic biopsy revealed malignant non-Hodgkins B-cell lymphoma. After pathologic confirmation, methotrexate chemotherapy and whole brain radiation therapy were done. Having experienced such a case, the authors strongly recommend to add primary CNS lymphoma as one of the differential diagnoses to brain abscess, metastatic brain tumor and glioblastoma multiforme in cases of multiple ring enhancing periventricular lesions of immunocompromised patient or organ recipient.

Pulmonary lymphangioleiomyomatosis is a rare disease, prevalent in women of reproductive age, and characterized by proliferation of atypical smooth muscle in the lung. A 44-year-old women with pulmonary lymphangioleiomyomatosis was presented. Chest radiographs showed diffuse increased reticulonoular infiltrations on the almost entire lung and high resolution CT illustrated multiple, well defined cystic lesions which were distributed diffusely through the lung. Histologic confirmation of lymphangioleiomyomatosis was made upon open lung biopsy. Treatment with methylprogesterone was initated.

Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.

A 45-year-old man was referred with symptoms of cough and chest pain for 3 days and small amount of hemoptysis. He had no history of pulmonary tuberculosis. Chest CT showed 2 cystic lesions with air fluid level ill right lower lobe. We performed posterior basal segmentectomy and found 2 cysts with white long parasite in each cavity. We experienced a case of pulmonary sparganosis and report it with references.
