HYPOTHESIS Widespread use of computed tomography and ultrasound has led to the identification of increasing numbers of patients with asymptomatic cystic lesions of the pancreas. DESIGN Retrospective case series of patients with pancreatic cystic lesions. SETTING University-affiliated tertiary care referral center. PATIENTS Two hundred twelve patients with pancreatic cystic lesions seen in...

Two patients presented with unusually dilated Virchow-Robin spaces appearing as cystic lesions of varying size with signal intensity identical to the cerebrospinal fluid on all magnetic resonance pulse sequences. However, fluid-attenuated inversion-recovery (FLAIR) images disclosed small, high intensity foci adjacent to these cystic lesions in one patient. These high intensity foci on FLAIR ima...

We report two cases of cystic lesions in the head and neck, one a cystic schwannoma and the other a neurofibroma, both of which showed fluid-fluid levels on MR images. The differential diagnosis of fluid-fluid levels in the head and neck region should include cystic hygromas, aneurysmal bone cysts, soft-tissue cavernous hemangiomas, and simple bone cysts.

We present a case report to show how manganese-enhanced T1- and T2-weighted MR cholangiography could differentiate cystic parenchymal lesions from cystic abnormalities which communicate with the bile ducts.

of patients with postprimary tuberculosis (1). However, cystic change associated with pulmonary tuberculosis has rarely been reported in radiologic and pathologic studies (2-4). According to these reports, cystic change developed before or during antituberculous chemotherapy in patients with pulmonary tuberculosis that initially presented with acute respiratory failure. Furthermore, these cysti...

Transrectal longitudinal ultrasonography was performed in 34 patients with chronic non-bacterial prostatitis. Prostatic stones and cystic lesions were associated with chronic non-bacterial prostatitis in 67.6% and 11.8%, respectively. The annual relapse rates of clinical symptoms were related to the presence of prostatic stones and cystic lesions. Transrectal ultrasonography plays a very import...

A large maxillary cyst was treated for 3 months with marsupialization and decompression, followed by surgical endodontic therapy of the affected teeth and cystectomy. Although small cystic lesions will typically heal with nonsurgical endodontic therapy, larger lesions may need additional treatment. Surgical enucleation of a large cystic lesion may lead to damage of other teeth or anatomic struc...

The purpose of this article is to highlight the imaging features of cystic pancreatic tumors. Common cystic pancreatic tumors include serous microcystic adenomas, mucinous cystic tumors, intraductal papillary mucinous neoplasms and solid pseudopapillary tumors. These tumors have characteristic imaging features, especially on magnetic resonance imaging (MRI) and MR cholangiopancreaticography exa...

Retroperitoneal cystic lymphangioma is a rare benign tumor. Most patients eventually experience some symptoms that necessitate therapeutic intervention. Excision is the treatment of choice, and some cases of laparoscopic resection have been reported. We report another case of a huge retroperitoneal cystic lymphangioma that was successfully excised laparoscopically with the SAND balloon catheter...

Extensive preoperative assessment of hepatic metastases is required in colon cancer patients. We report a case in whom the preoperative investigation by ultrasound scan and contrast-enhanced computed tomography revealed numerous cystic lesions of the liver, suspicious of von Meyenburg complex. Magnetic resonance and magnetic resonance cholangiographic images demonstrated typical features of von...
