    Notes: Abstract. We describe CT findings of a case of mucin-hypersecreting papillary cholangiocarcinoma (MHPC), with extrahepatic bile leakage to the rectus abdominis muscle via the ligamentum teres hepatis forming an abdominal wall abscess. Endoscopic retrograde cholangiography was unsatisfactory. Spiral three-dimensional CT cholangiography was helpful in assessing the resectability of MHPC by offering anatomic details of the uninvolved biliary tree.

    Notes: Abstract. Background: To study the biological behavior of renal squamous cell carcinoma (RSCC). Methods: Fifteen cases of RSCC were retrospectively studied. These cases were classified as central (eight cases) and peripheral (seven cases) types by the tumor location. The clinical data and computed tomographic findings were analyzed and compared. Results: High incidence (87%) of urolithiasis was observed. The prognosis of RSCC was very poor, with a median survival time of 3.5 months. The infectious symptoms, central location, and modified stage IV of the tumor were the poor prognostic factors of RSCC. Two types of RSCC were different in the presenting symptoms, lymph node metastasis, modified tumor staging, and survival time. Conclusion: The central and peripheral types of RSCC were different biologically. High index of suspicion should be maintained when identifying the subtle clues of malignancy in patients with urolithiasis.

    Notes: Abstract We describe a case of renal leiomyoma in a 21-year-old woman who presented with flank pain and hematuria. Urographic and computed tomographic (CT) studies revealed a large right renal mass with polypoid outgrowth protruding into the renal pelvis. Cortical renal leiomyoma with this radiographic manifestation is extremely rare.

    Small bowel obstruction due to phytobezoar: CT diagnosis (1997)

    Notes: Abstract. We report two cases of small bowel obstruction (SBO) due to phytobezoar impaction. In both cases, computed tomography (CT) demonstrated a well-defined, ovoid intraluminal mass with mottled gas pattern within the dilated small bowel at the site of obstruction and an abruptly collapsed lumen beyond the lesion. Recognition of these CT findings allows specific preoperative diagnosis of SBO owing to this uncommon lesion.

    Unusual liver MR findings of Wilson's disease in an asymptomatic 2-year-old girl (1998)

    Notes: Abstract. We describe the unusual magnetic resonance (MR) findings of a case of Wilson's disease (WD) in an asymptomatic 2-year-old girl. Preenhanced computed tomography revealed multiple hyperdense areas in the liver. These lesions were hyperintense on T1-weighted and hypointense on T2-weighted MR images, results that might be ascribed to the paramagnetism of copper deposited in liver at a relatively early stage of the disease before severe liver cirrhosis had evolved.

    Notes: Abstract An unusual case of rapid-growing posttraumatic gluteal epidermal cyst with ischiorectal and presacral extension is reported. Pertinent clinical history and magnetic resonance imaging allowed accurate preoperative diagnosis. Cautious complate excision was important to prevent recurrence. To our knowledge, posttraumatic gluteal epidermal cyst with this unusual clinical presentation has not been described previously.

    Notes: Abstract Pyogenic liver abscess is a rare complication of ventriculoperitoneal (VP) shunting. We report a 4-month-old female with this complication who was successfully treat ed by computed tomography-guided percutaneous transhepatic catheter drainage, shunt externalization, and parenteral antibiotics. Liver abscess is a possible intra-abdominal complication of VP shunting, and imaging studies are good adjuncts in making the clinical diagnosis.

    MRI in recurrent nasopharyngeal carcinoma (1999)

    ISSN: 1432-1920

    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract In this study, we retrospectively reviewed the MRI features of recurrent nasopharyngeal carcinoma (NPC) in 72 patients who underwent MRI before and after gadolinium injection. Recurrent NPC exhibited a high degree of regional spread and a variety of signal intensities and contours. MRI showed a nasopharyngeal mass in 50 patients (69.4 %); other sites of involvement included the parapharyngeal space (44.4 %), nasal cavity (12.5 %), paranasal sinuses (27.8 %), oropharynx (4.2 %), orbit (8.3 %), infratemporal fossa (18.1 %), skull base (59.8 %), intracranial area (51.4 %) and regional lymph nodes (15.3 %). On T2-weighted images, the nasopharyngeal mass gave high signal in 9 of 50 cases (18 %), intermediate in 27 (54 %), mixed in 8 (16 %) and low signal in 6 (12 %). Contrast enhancement was strong in 12 cases (24 %), moderate in 29 (58 %) and heterogeneous in 9 (18 %). The lesion was convex in 31 cases (62 %) and concave or straight in 19 (38 %). Recognition of the distribution and the appearance of recurrent NPC on MRI is essential for timely diagnosis and appropriate treatment.

    Notes: Abstract A 35-year-old woman presented with a 6-month history of intermittent headaches, vomiting and dizziness. CT showed a plaquelike mass with tiny calcifications along the surface of the left frontal lobe. The mass exhibited heterogeneous enhancement with a few lowdensity foci. Underlying sulcal obliteration and enhancement and white matter oedema were also noted. Histopathological examination of excised material was consistent with tuberculoma. Recognition of this unusual presentation of intracranial tuberculoma may facilitate appropriate diagnosis and management.

    Nasopharyngeal carcinoma: MRI and CT assessment (1997)

    Notes: Abstract Precise assessment of the extent of nasopharyngeal carcinoma (NPC) represents the basic step towards optimal treatment. We compared the capacity of CT and MRI in assessing the extent of NPC in 67 patients. MRI was superior to CT in demonstrating lesions in the retropharyngeal node, skull base, intracranial area, carotid space, longus colli muscle and levator palatini muscle. Of 25 cases in which retropharyngeal adenopathy was recognised only on MRI, seven had been reported as showing oropharyngeal involvement and 18 as primary extension to the carotid space on CT. MRI showed skull-base involvement in 40 patients compared with 27 on CT and intracranial involvement in 38 patients versus 24 on CT. There was not a single case in which skull base invasion was seen on CT but not on MRI. MRI enabled improved recognition of tumour infiltration of longus colli muscles (34 cases compared with 15 on CT). It allowed us to clarify 12 questionable sinonasal opacities on CT. Overall, T-staging was changed in 18 of 67 patients (26.9 %), including upstaging in 15 cases and downstaging in 3 cases, after comparing CT with MRI. The nodel status was changed from negative on CT to positive on MRI in 4 of 67 patients (6 %). We believe that MRI allows more accurate evaluation of the extent of NPC than CT and should be the primary mode of investigation.
