Solid and Papillary Epithelial Neoplasm of the Pancreas: Radiologic and Pathologic Correlationt

PURPOSE: Computed tomographic(CT), ultrasonographic(US) findings of solid and papillary epithelial neoplasm of the pancreas were correlated with pathologic findings for the better understanding of this disease entity. METHODS AND MATERIALS: A retrospective review of CT and US of 14 cases of solid and papillary epithelial neoplasm of the pancreas was carried out in terms of the margin, internal architecture, caicification and septation, and this was correlated with gross pathologic findings. RESULTS: CT and US findings were well defined round masses consisting of both solid and cystic components. Five cases were cystic, four cases were solid and five cases were mixed. Cystic portion of the tumor represented variable degree of hemorrhagic necrosis. Six cases contained foci of calcification, which were linear, marginal and amorphous. Marginal calcification interfered US examination of the mass in three cases. Internal septurn was demonstrated in four cases on CT, one case on US and three cases on gross specimen. CONCLUSIONS: Our results indicate that calcification and internal septurn were considered as a part of radiologic findings in solid and papillary epithelial neoplasm of the pancreas.

Atypical manifestation of solid and papillary epithelial neoplasm of the pancrease: case report

We report a rescently experienced case with atypical radiologic manifestation of solid and papillary epithelial neoplasm of the pancreas in a 37 years old female patient. The tumor had heavy calcification on its capsule wall and septa. Instead of the usual encapsulated lesion with partly solid and partly cystic-hemorrhagic components, the lesion consisted of numerous fine cavitations containing air without fluid component except focal abscess fluid.

Multicystic mesothelioma of the peritoneum: case report

Cystic mesothelioma of the peritoneum is a rare benign neoplasm that occurs predominantly in young to middle-aged women and tends to recur locally. Pelvic viscera is the most common predilection site of cystic mesothelioma. Authors report a case of multicystic mesothelioma of the pelvic pelvic peritoneum. The pelvic ultrasonography showed a large, confluent, and thin-walled multilocular cystic mass occupying the pelvic cavity and lower abdomen. The cystic mass was flattened and elongated. Each cyst of variable size was separated by thin septa and filled with translucent fluid. Cystic mesothelioma should be included in the differential diagnosis of the cystic peritoneal masses, especially in reproductive-aged women.

Evaluation of laryngeal carcinoma by computed tomography

The limitation so direct or indirect laryngoscopy and laryngogram in detemining the exact site and anatomiclocation of laryngeal carcinoma were well documented by many authors. As compared with laryngoscopy and laryngogram, CT study for laryngeal cancer is more exact and accurate method demonstrating anatomic sites of involvement, invasion into deep soft tissue spaces of endolarynx, destruction of laryngeal cartilages and cervical metastasis. Fourteen laryngeal cancer patients proven by laryngoscopic biopsy were further examined by computed tomography for staging. The authors compared laryngoscopic findings with those of computed tomography, and their clinical, surgical and computed tomographic findings were analysed. The results were as follows; 1. All patients were proved as squamous cell carcinoma. They were 12 males and 2 females aged over 50 yrs. 2. Common clinical symptoms were hoarseness, dysphagia and swallowing difficulty. The pirmary anatomic sites determined by CT were 8 transglottic, 2 glottic, 2 supraglottic and 1 pyriform sinus respectively. They were 2 T1. 7 T2, 1 T3, 3 T4 by TNM systems, respectivly. (One case was difficult to evaluate exactly). 3. Invasion into deep soft tissue spaces of endolarynx, cartilage destruction, and neck metastasis were relatively predominant in transglottic caracinomas. 4.CT was superior in evaluating tumor invasion, especially into deep soft tissue spaces of endolarynx, laryngeal cartilages and metastasis ot soft tissue and lymph nodes of neck. However CT had some limitation in determining primary site of laryngeal cancer.

Unusual manifestation of right upper lober collapse due to bronchogenic carcinoma

In the unusual manifestation of right upper lobe collapse confusing with mediastinal or parenchymal mass, both alteration of the pulmonary vessels and shifting pattern of the collapsed lobe to the periphery on supine positionare the key to the diagnosis of it rather than mediastinal or parenchymal mass. The mechanisms of these unusual manifestation s are obscure, however lobar torsion and gravity factor are considered to be a main process. Authors have experienced 2 cases of unusual manifestations of right upper lobe collapse due to bronchogenic carcinomaduring resent 2 years in Kyung Hee University hospital, and prsent radiologic findings.
