Peritoneal tuberculosis with elevated CA-125 mimicking ovarian cancer with carcinomatosis peritonei: Crucial CT findings.

Preoperative diagnosis of peritoneal tuberculosis is often difficult because of confusion with ovarian cancer. A 56-year-old woman was admitted to our hospital with abdominal fullness. Ascites, prominent bilateral ovaries, and elevated CA-125 were noted.

Case 210: Primary ovarian lymphoma.

History A 45-year-old woman presented with a 4-day history of abdominal discomfort, nausea, and vomiting and a 1-month history of poor appetite and weight loss. Her white blood cell count was normal. Physical examination revealed a palpable mass in the abdominopelvic region.

Follicular dendritic cell sarcoma of the omentum: multidetector computed tomography findings.

We report computed tomography (CT) findings for a rare case of follicular dendritic cell sarcoma of the greater omentum from a 47-year-old female patient. The tumor presented ash a palpable mass lesion in the umbilical region for the last two months. Multidetector CT scan of the abdomen showed a 14-cm soft-tissue mass with calcification and necrosis within the greater omentum.

Inflammatory pseudotumor of the spleen: CT and MRI findings.

Inflammatory pseudotumors rarely occur in the spleen. We report such a case with characteristic computed tomography (CT) and magnetic resonance imaging (MRI) findings. A CT scan showed an isodense nodular mass with gradual mild enhancement on delayed-phase contrast-enhanced images.

Magnetic resonance imaging of gluteal intramuscular myxoma.

Gluteal intramuscular myxomas with MR images have not been reported before. A 45-year-old man presented with a palpable mass in his right buttock for several months. Magnetic resonance imaging showed an intramuscular cystic lesion with homogeneous signal intensity at the right gluteus muscle, and the mass had thin peripheral enhancement after gadolinium administration.

Penile gangrene in a patient on renal dialysis: CT findings.

We presented a case of a 63-year-old man with type 2 diabetes mellitus and end-stage renal disease on hemodialysis. Precontrast CT images showed atrophy of kidneys bilaterally and calcification of the abdominal aorta, small branches of bilateral renal arteries and small arteries of the pelvis, including the internal pudendal artery and penile artery. Postcontrast CT scans revealed a nonenhancing glans penis with a clear margin relative to normal tissue.

Computed tomography angiography in detection and characterization of ruptured anterior cerebral artery aneurysms at uncommon location for emergent surgical clipping.

Introduction: Cerebral subarachnoid hemorrhage may result from rupture of saccular aneurysms at uncommon location [excluding the anterior communicating artery (ACOM)] of the anterior cerebral artery (ACA). The purpose of this study was to evaluate the usefulness of helical computed tomography angiography (CTA) in detection and characterization of intracranial aneurysms at such uncommon locations before emergent surgical clipping.

Materials And Methods: Between 1998 and 2003, records for 50 consecutive patients who underwent emergent surgical clipping for intracranial aneurysms were reviewed.

Malignant transformation of an ovarian mature cystic teratoma: computed tomography findings.

Introduction: The malignant transformation of an ovarian mature cystic teratoma is rare. We presented such a case of a 46-year-old woman with characteristic computed tomography (CT) findings.

Case Report: The patient had suffered from fullness and tenderness of the lower abdomen for one year.

MRI of epidermoid cyst of the conus medullaris.

Study Design: A case report of an epidermoid cyst in the conus medullaris with characteristic magnetic resonance imaging (MRI) findings.

Objective: To describe an epidermoid cyst in the conus medullaris with characteristic MRI findings and point out these findings that correlated well with histologic findings.

Setting: Taiwan.

Radiographic appearance and clinical outcome correlates in 26 patients with severe acute respiratory syndrome.

Objective: We aimed to evaluate the appearance of chest radiographs in patients with severe acute respiratory syndrome (SARS) and correlate these findings with clinical outcomes.

Materials And Methods: We retrospectively reviewed the initial radiograph and a series of follow-up chest radiographs in 26 patients who had symptoms and signs consistent with SARS. Twenty-five patients completed the full course of radiographs in the hospital.
