Adenomyosis within a uterine septum in a patient with secondary infertility.

BACKGROUND: Adenomyosis is a benign infiltration of endometrial stroma and glands into the myometrium. Until the advent and advancement of imaging techniques such as transvaginal ultrasound scan (TVUS) and magnetic resonance imaging (MRI), the diagnosis of adenomyosis could only be made with confidence using histology following hysterectomy. CASE: The patient is a 37-year-old woman, with a long history of secondary infertility. A hysterosalpingogram (HSG) and a pelvic MRI showed two separate uterine cavities. The patient underwent laparoscopy and hysteroscopy revealing a bicornuate appearance of the uterus and a uterine septum. Resection of the septum showed adenomyosis on histologic examination. COMMENT: Adenomyosis of uterine septum should be considered if MRI shows features of adenomyosis elsewhere in the uterus with thickened junctional zone. Further research is needed to investigate this association with the pathogenesis of adenomyosis.

Pancreatic imaging: current and emerging technologies.

This review discusses the current imaging modalities for the diagnosis and staging of solid and cystic pancreatic lesions and for the assessment of acute and chronic pancreatitis, and the future role of emerging technologies in the management of pancreatic diseases. Multidetector row spiral computed tomography is superior to conventional single-detector row spiral computed tomography in the detection and staging of pancreatic adenocarcinoma. Positron emission tomography is a sensitive but relatively nonspecific diagnostic modality. Positron emission tomography-computed tomography fusion may improve the staging accuracy for pancreatic cancer. Echo-enhanced ultrasound may have an emerging role in evaluating pancreatic masses. Endoscopic ultrasound with fine needle aspiration for cytology is the single best method for diagnosis and staging of nonmetastatic pancreatic cancer with a high accuracy for determining tumor resectability. In acute pancreatitis, a modification of the standard computed tomography severity index, which places greater emphasis on extrapancreatic complications, has shown superior correlation with various patient outcome measures. Endoscopic retrograde cholangiopancreatography is still the test of choice for morphological evaluation of chronic pancreatitis, whereas magnetic resonance cholangiopancreatography offers a noninvasive alternative in selected patients. Endoscopic ultrasound can be useful for detecting early chronic pancreatitis. Secretin-stimulated imaging techniques may eventually provide a noninvasive method of reliably assessing pancreatic exocrine function.
