Spontaneous regression of a cystic retroperitoneal tumour in young women postpartum. Report of two cases.

Retroperitoneal cystic tumours are rarely found, and of these, the most common lesion is a cystic lymphangioma. We present two postpartum patients with a cystic retroperitoneal tumour which showed spontaneous regression and a review of the literature.

Limited amounts of dendritic cells migrate into the T-cell area of lymph nodes but have high immune activating potential in melanoma patients.

Purpose: The success of immunotherapy with dendritic cells (DC) to treat cancer is dependent on effective migration to the lymph nodes and subsequent activation of antigen-specific T cells. In this study, we investigated the fate of DC after intradermal (i.d.

Hepatocystin is not secreted in cyst fluid of hepatocystin mutant polycystic liver patients.

Autosomal dominant polycystic liver disease (PCLD) is characterized by multiple liver cysts and is caused by mutations in PRKCSH (hepatocystin). Mechanisms of cystogenesis are unknown, but previous studies have shown that hepatocystin is secreted in vitro. The goal of this study was to determine the fate of hepatocystin in vivo.

Aspiration-sclerotherapy results in effective control of liver volume in patients with liver cysts.

Purpose: To study the extent to which aspiration-sclerotherapy reduces liver volume and whether this therapy results in relief of symptoms.

Results: Four patients, group I, with isolated large liver cysts, and 11 patients, group II, with polycystic livers, underwent aspiration-sclerotherapy. Average volume of aspirated cyst fluid was 1,044 ml (range 225-2,000 ml) in group I and 1,326 ml (range 40-4,200 ml) in group II.

Preoperative 3T MR imaging of rectal cancer: local staging accuracy using a two-dimensional and three-dimensional T2-weighted turbo spin echo sequence.

Purpose: The purpose of our study was to evaluate the image quality and diagnostic performance of two-dimensional (D) turbo spin echo (TSE) and 3D T2-weighted TSE MR imaging in local staging of rectal cancer at 3T.

Materials And Methods: 3T phased-array MR imaging was performed in 36 consecutive patients with biopsy-proven rectal cancer. High-resolution 2D TSE images in three planes and 3D TSE images of the rectum were obtained.
