Tracheopathia osteoplastica is a rare benign disorder of the trachea and major bronchi. It is characterized by multiple cartilaginous or osseous submucosal nodules that project into the tracheobronchial lumen. Awareness of the condition is important to avoid unnecessary surgery. We report here on the CT and bronchoscopic findings of tracheopathia osteoplastica associated with anthracofibrosis in a 67-year old woman, and we will then discuss our findings.

Acute appendicitis is the most common reason for non-obstetric abdominal surgery during pregnancy. The diagnosis of appendicitis in pregnancy is difficult due to the blunting of signs and symptoms during pregnancy along with a migration of appendiceal location. When appendicitis in pregnancy is suspected, the physician must balance the risk of delaying surgery and incurring the morbidity of delay against acting hastily and performing unnecessary surgery. Eleven patients who underwent appendectomy during pregnancy from April 1995 through February 1997 were reviewed. Seven patients were proven to be acute appendicitis at laparotomy and by subsequent histopathology. There were no significant differences between patients with positive and negative laparotomies regarding frequency of presenting symptoms and signs or laboratory results. Two cases of preform(25 and 31 weeks) deliveries occurred, one with a perforated appendicitis and the other with negative laparotomy.

Congenital megacalyces is a congenital renal disease characterized by hypoplasia of the medulla and a non-obstructive dilatation of the calyces. More than 100 cases have been reported in the literature after first described by Puigvert in 1963, but it has been reported only three cases (two cases of adults and one case of child) in the literatures in Korea. The etiology of the congenital megacalyces is unknown. Renal pelvis and ureter are mostly normal in size and there is no urinary obstruction or reflux. Renal medulla of congenital megacalyces is thinner than that of normal kidney but renal cortex retains its normal thickness and function. This is features that help to distinguish megacalyces from obstructive atropy. The calyces are polygonal in shape and the majority of kidney with megacalyces have increased number of calyces. Since congenital megacalyces is a non-progressive lesion, it is important to recognize the clinical entity and avoid unnecessary surgery. We report one case of congenital megacalyces without urinary obstruction or reflux with a brief review of related literatures.

Perforated appendicitis with an abscess formation is known to be the most common cause of tender mass in right lower abdomen. The differential diagnosis of a tender mass in right lower abdomen, however, is broad and includesvarious intraabdominal and intrapelvic lesions in origin. Preoperative accurate diagnosis is essential in order toavoid unnecessary surgery or complications resulting from delayed surgery. The purpose of this pictorial essay isto illustrate examples of various causes and methods to differentiate them with ultrasonography and CT.

Intraoperative fracture in total knee arthroplasty (TKA) is a rare complication. However, when it happens, additional surgery to fix the fracture site is needed. Therefore, it is important to diagnose intraoperative fractures in TKA exactly. The authors experienced two cases of cortical perforation of medial femoral condyle misidentified as the fracture in TKA. Cortical perforation could be misdiagnosed as the fracture, which could lead to unnecessary surgery. This is the first report about cortical perforation in TKA. We report two cases of intraoperative cortical perforations and describe the radiological characteristics.

Endoscopic biopsy is the most popular diagnostic procedure for gastric epithelial neoplasm. However, discrepancy between biopsy and endoscopic resection diagnosis occasionally occurs and leads to an unnecessary procedure. A negative pathologic diagnosis following endoscopic resection is particularly problematic. In this context, we reviewed factors that may be associated with a diagnostic discrepancy between endoscopic biopsy and endoscopic resection, with focus on crypt dysplasia.

Primary segmental omental infarction in adults is very rare and occasionally occurs due to impaired perfusion to the greater omentum. Most authors believe that the condition results from an embryologic variant associated with anomalous and fragile blood supply of the right lower portion of the greater omentum, which is consequently susceptible to infarction. Since there are no characteristic clinical findings, the clinical presentation often mimics acute appendicitis or cholecystitis. However, in the proper clinical setting, the correct diagnosis can be established by the radiologist; therefore, unnecessary surgery can be avoided in many cases. Cross-sectional imaging by ultrasound or computed tomography will demonstrate characteristic findings in a location corresponding to the patient's point of maximal tenderness. These findings consist of an ovoid or cake-like mass in the omental fat with surrounding inflammatory changes. We report a case of primary segmental omental infarction in an adults who was treated conservatively after the diagnosis was established with clinical findings.

There are many causes of chronic abdominal pain and abdominal protrusion. But, they are likely to be confused with diabetic thoracic polyradiculopathy. Differentiation between this self-limiting complication and abdominal herniation is important to avoid unnecessary procedure. We describe the case of 77-years-old man with 10 years history of non-insulin dependent diabetes mellitus, who was suffering from postherpetic neuralgia for 10 months and presented with a abdominal segmental paresis and protrusion. The paraspinal electromyography showed bilateral lower thoracic radiculopathy.

We report a case of an 86-year-old man diagnosed with bilateral elastofibroma dorsi who was managed conservatively after a two year follow-up. An elastofibroma dorsi is a benign, slow-growing tumor that is most often located in the inferior periscapular area in elderly patients. It should be considered to differentiate them from other soft tissue tumors located at the inferior periscapular region. Increased awareness of these characteristics will decrease the incidence of a misdiagnosis of elastofibroma dorsi as a malignancy and avoid unnecessary surgery.

IgG4-related sclerosing disease is a disease entity that has recently attracted attention, manifesting as a multiorgan disease characterized by high serum IgG4 levels, extensive IgG4-positive plasma cells and lymphocyte infiltration of the affected organs, with the pancreas (autoimmune pancreatitis) and kidney as representative targets. In cases of renal involvement, parenchymal lesions are predominant, such as renal cortical lesions or diffuse renal enlargement. However, mass-like lesions involving the renal pelvis are very rare, and mass forming or pelvic involvement types should be distinguished from lymphomas, metastatic cancers and other genitourinary malignancies to avoid unnecessary surgery. Herein, we report a case of IgG4-related sclerosing disease involving the kidney as an unusual involvement pattern presenting as a mass-like lesion with pelvic and perirenal involvement.
