  • Pulmonary capillary hemangiomatosis (PCH) is a rare disease of unknown etiology that is characterized by nodules composed of infiltrating capillary blood vessels. Herein, we describe a case of a PCH-like lesion that was detected by chest computed tomography. Transthoracic needle aspiration resulted in life-threatening hemorrhage. The patient was followed for seven years. He remained in good health and a follow up image showed little interval change.

  • Background and Objectives: The introduction of highly sensitive imaging techniques has made it possible to detect many non-palpable nodules, or“incidentaloma”in the thyroid. Discovery of these lesions raises concerns about their malignancy, but the optimal strategy for managing these lesions has not been clearly established. This study was designed to evaluate the usefulness of ultrasonographic exam with new diagnostic criteria and presume the value of mass screening for thyroid cancer. Materials and Methods : Mass screening for thyroid cancer were carried out in conjunction with mass screening for breast cancer. The subjects were 630 women aged 30 years or over. Thyroid glands were examined with 10 MHz transducer ultrasonography by one radiologist. Needle aspiration biopsy were performed when suspicious of malignancy under the new diagnostic criteria. Results and Conclusion : The new ultrasonographic criteria to diagnose thyroid cancer provided useful information and ensured more accurate evaluation. 7 cases of thyroid cancer were discovered and successfully managed. It should be further demonstrated that there is sufficient value of mass screening for thyroid cancer to perform it independently despite early cancer detection.

  • Ultrasound has emerged to become a commonly used modality in the performance of chronic pain interventions. It allows direct visualization of tissue structure while allowing real time guidance of needle placement and medication administration. Ultrasound is a relatively affordable imaging tool and does not subject the practitioner or patient to radiation exposure. This review focuses on the anatomy and sonoanatomy of peripheral non-axial structures commonly involved in chronic pain conditions including the stellate ganglion, suprascapular, ilioinguinal, iliohypogastric, genitofemoral and lateral femoral cutaneous nerves. Additionally, the review discusses ultrasound guided intervention techniques applicable to these structures.

  • Fine needle aspiration (FNA) cytology of breast disease is recognized to be highly accurate and cost effective, especially when this is used in combination with clinical examination and imaging as part of a triple approach. A probabilistic/categorical approach is used for the classification of breast FNA specimens. Criteria are defined from the perspective of the likelihood of making a definitive diagnosis of cancer on excision. This approach is an accurate way of classifying breast FNA specimens, and this can be reliably applied regardless of the level of experience of the pathologist for interpreting the case. When a definitive diagnosis of malignancy is made, the next step is to determining the specific histologic types of the malignancy according to their cytological features. In order to make an accurate diagnosis of carcinoma and for correct typing a tumor, an adequate, correctly sampled aspirate without any other artifacts is required.

  • The role of remote sensing in phenological studies is increasingly regarded as a key in understanding large area seasonal phenomena. This paper describes the application of Moderate Resolution Imaging Spectroradiometer (MODIS) time series data for vegetation classification using seasonal variation patterns. The vegetation seasonal variation phase of Seoul and provinces in Korea was inferred using 8 day composite MODIS NDVI (Normalized Difference Vegetation Index) dataset of 2006. The seasonal vegetation classification approach is performed with reclassification of 4 categories as urban, crop land, broad-leaf and needle-leaf forest area. The BISE (Best Index Slope Extraction) filtering algorithm was applied for a smoothing processing of MODIS NDVI time series data and fuzzy classification method was used for vegetation classification. The overall accuracy of classification was 77.5% and the kappa coefficient was 0.61%, thus suggesting overall high classification accuracy.

  • A dog with anorexia, cough, and regurgitation was referred to clinic. Diagnostic imaging revealed a solitary mass involving the right cranial and middle lung lobes, compression of the cranial vena cava, and deviation of the heart and mediastinum toward the left side because the mass. The mass was diagnosed as a squamous cell carcinoma via fine needle aspiration. Ten days later, the tumor was larger and the clinical signs were more severe. A combination of piroxicam and itraconazole was administered to control the mass. Two weeks after initiating this treatment, the tumor size decreased and the clinical signs improved significantly.

  • A 17-year-old neutered male Miniature Pinscher dog presented with a mass on the left side of the submandibular region. Fine needle aspiration revealed malignant epithelial cells from the salivary gland but no evidence of metastasis was found on radiography, ultrasonography, or computed tomography. The cervical mass was surgically resected, and the histopathological examination confirmed adenocarcinoma of the mandibular salivary gland. Seven months after the initial diagnosis, the dog is alive without any clinical signs. This report describes the clinical findings, cytology, diagnostic imaging, and histopathological characteristics of a mandibular salivary gland adenocarcinoma in a Miniature Pinscher dog.

  • A 12-year-old castrated male Persian cat presented with abdominal distension and anorexia. The radiography revealed ascites, pleural effusion, and a cranioventral mediastinal mass. Ultrasonography showed a well-defined mass lesion within a thickened ileal segment with a transmural loss of layering and multiple hyperechoic nodules arising from the peritoneum. Computed tomography showed peritoneal thickening with contrast enhancement, a bulky heterogeneous ileal mass, and mesenteric involvement with diffuse nodules. An alimentary lymphoma was confirmed by fine needle aspiration of the small intestinal mass. This report describes the imaging features of lymphoma with peritoneal lymphomatosis in a cat.

  • A 5-year-old neutered male domestic short-haired cat presented with acute dyspnea characterized by open-mouth breathing and stridor for 2 days. Direct visualization via laryngoscopy revealed diffuse laryngeal swelling and severe thickening of the vocal folds bilaterally; thus, the upper respiratory tract was obstructed owing to severe edema. Neutrophil infiltration was found on fine needle aspiration of the larynx cytology, and no discrete mass with polyp or neoplasia was identified on diagnostic imaging. The cat was diagnosed with acute obstructive laryngitis, and a tracheostomy tube was immediately installed. After 17 days of treatment with steroids, doxycycline and azithromycin, the swollen larynx gradually improved, and there was no recurrence of laryngitis or respiratory obstruction. A feline upper respiratory polymerase chain reaction panel revealed Mycoplasma felis infection; however, it could not be determined whether it was pathogenic or opportunistic. Herein, we report a case of obstructive laryngitis in a cat. When respiratory obstruction due to acute laryngitis is identified, a good prognosis is expected with rapid and appropriate treatment.

  • A 2-year-old outdoor, spayed, female Korean Jindo dog was referred for thoracic and abdominal masses. Diagnostic imaging revealed generalized lymphadenopathy and a significant amount of pleural effusion. The cytological evaluation of the pleural effusion and fine-needle aspiration of the mediastinal lymph nodes confirmed the presence of fungal hyphae. The histopathological examination of the mediastinal lymph nodes stained with Grocott's methenamine silver revealed fungal mycelia, and Aspergillus terreus was identified based on fungal DNA sequencing. Thus, the dog was diagnosed with disseminated canine aspergillosis caused by A. terreus. This case report describes a rare case of disseminated canine aspergillosis caused by A. terreus in a Korean Jindo dog.
