A 4-year-old Holstein cow with progressive atrophy and ataxia was submitted for diagnosis. The postmortem examination revealed multifocal yellowish nodules in the pulmonary parenchyma and vegetative masses in the mitral and tricuspid valve of the heart. Both kidneys were severely enlarged, with multiple yellow nodules on the parenchyma. Histopathologically, pulmonary abscesses, vegetative endocarditis, suppurative glomerulonephritis, and fibrino-purulent arthritis were observed. The tiny β-hemolytic bacterial colonies were isolated from the lesions and identified as Arcanobacterium haemolyticum by the VITEK 2 system (bioMérieux, USA). This is the first documented report of an A. haemolyticum infection in a Holstein cow in Korea.

Alveolar echinococcosis (AE) is considered as a fatal zoonosis caused by the larvae of Echinococcus multilocularis. The lungs and brain are the most common metastatic organs. We report a human case of hepatic alveolar echinococcosis accompanied by lung and brain metastasis. In particular, the patient had a history of tuberculosis and the lung lesions were easily misdiagnosed as lung abscesses. The lesions of liver and lung underwent radical resection and confirmed as alveolar echinococcosis by pathological examination. The patient had no surgical complications after operation and was discharged after symptomatic treatment. Unfortunately, the patient later developed multiple intracerebral AE metastases. We required the patient to take albendazole orally for life and follow up.

Clonorchiasis is common in Korea. The coinfection of amebic abscess with clonorchiasis is not rare in endemic areas. The coinfection may influence on its manifestations each other. We experienced a human case with unusal manifestation of amebic liver abscess associated with coinfection by Clonorchisis sinensis. The case was an 80-year-old female. She lived in Yongil-gun, Kyongsangbuk-do, Korea, She had multiple amebic abscess cavities in the liver, one of which subsided spontaneously and others newly appeared. She was diagnosed by CT guided aspiration of the cyst, which revealed trophozoites of ameba and eggs of C. sinensis. She was treated with praziquantel and metronidazale and was cured.

Acupuncture has been widely used in alternative medicine for pain relief but may have many complications due to lack of appropriate cares. Pharmacopuncture is a sort of acupuncture that injects a herbal ingredient through a thin tube for the purpose of combining the effects of the herb and acupuncture and it has many pitfalls. The agents, used in pharmacopuncture are not refined for a desired effect and not produced by sterile standard processes under strict medical surveillance. We, report a case of a 44-yr-old male patient who had multiple abscesses in the psoas region with fever, right low back and hip pain that began after the pharmacopuncture treatment. This case shows that although pharmacopuncture has been practiced widely, it is important that the appropriate aseptic technique should be used to prevent severe infections and other complications.

Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe. We performed a craniotomy and abscess removal. Bacteriological culture proved negative. Her chest computed tomography (CT) showed multiple AVFs. Therapeutic embolization of multiple pulmonary AVFs was performed and antibiotics were administered for 8 weeks. A 45-year-old woman presented with a 7-day history of progressive left hemiparesis. She had no remarkable past medical history or family history. On admission, blood examination showed a white blood cell count of 6290 cells/uL and a high sensitive C-reactive protein of 2.62 mg/L. CT and MR imaging with MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex with marked perilesional edema that suggested a brain abscess. A chest CT revealed a pulmonary AVF in the right upper lung. The pulmonary AVF was obliterated with embolization. There needs to consider pulmonary AVF as an etiology of cerebral abscess when routine investigations fail to detect a source.

Scedosporium apiospermum, the anamorph of Pseudallescheria boydii, is a ubiquitous saprophytic fungus. S. apiospermum can cause life-threatening infections usually in immunocompromised patients or after near-drowning incidents. Here, we report the first case of disseminated infection caused by S. apiospermum after near-drowning in Korea. A 44-year-old healthy man developed aspiration pneumonia, followed by multiple brain abscesses, and endopthalmitis, after a near-drowning incident in a septic tank. S. apiospermum infection was diagnosed on the 33rd day after the incident had occurred. The patient died from the progressive renal failure 255 days after incident, although he had been treated with voriconazole.

Purpose: Actinomycosis is an uncommon chronic granulomatous disease that presents as a slowly progressive, indolent, indurated infiltration with multiple abscesses, fistulas, and sinuses. The purpose of this article is to report on a case of actinomycosis with clinical findings similar to periodontitis. Methods: A 46-year-old female presented with recurrent throbbing pain on the right first and second molar of the mandible three weeks after root planing. Exploratory flap surgery was performed, and the bluish-gray tissue fragment found in the interproximal area between the two molars was sent for histopathology. Results: The diagnosis from the biopsy was actinomycosis. The clinical and radiographic manifestations of this case were clinically indistinguishable from periodontitis. The patient did not report any symptoms, and she is scheduled for a follow-up visit. Conclusions: The present study has identified periodontitis-mimicking actinomycosis. Actinomycosis should be included in the differential diagnosis in cases with periodontal pain and inflammation that do not respond to nonsurgical treatment for periodontitis. More routine submissions of tissue removed from the oral cavity for biopsies may be beneficial for differential diagnosis.

Purpose: Oral carcinoma cuniculatum is a rare well-differentiated variant of oral squamous cell carcinoma. The purpose was to systematically review its unique features to differentiate it from other variants as verrucous carcinoma, papillary squamous cell carcinoma and well-differentiated squamous cell carcinoma. Materials and Methods: A systematic review was performed using MEDLINE, Dentistry and Oral Sciences Source and PubMed databases and any existing articles related to the research subject missed in the search strategy to screen ones reporting cases occurring exclusively in the oral cavity in English literature. Variables analyzed included clinical, etiologic, imaging, histopatholgical features, treatment, follow-up and survival rates. Results: From 229 hits, 17 articles with 43 cases were included in the systematic review. Clinically it showed a female predilection with pain and/or ulceration of a relatively long duration and exudation being the most common symptoms. Histologically, it showed more endophytic features comprising well-differentiated squamous epithelium with absent or minimal cytological atypia and multiple keratin filled crypts or cuniculus. Inflammatory stromal reaction and discharging abscesses were reported in most of the cases. Bone destruction was predominant in most imaging features. Complete surgical resection with a safety margin was the treatment of choice in most of the cases with few recorded recurrence cases. Conclusion: Apprehensive knowledge of oral carcinoma cuniculatum unique features is essential to avoid its misdiagnosis and provide proper treatment especially for recurrent cases.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease involving apocrine-bearing sites. It is characterized by recurrent painful nodules and abscesses that potentially rupture, resulting in sinus tract formation, fistulas, and scarring. HS tends to be found in the intertriginous areas (i.e., the axillary, inguinal, and perianal areas of the body). HS may be uncommon for radiologists because its diagnosis is usually based on clinical assessment. However, diagnosis based solely on clinical manifestations can underestimate the severity of HS. Ultrasonography and MRI play a critical adjunct role in determining the severity and extent of the disease and greatly aid its management. Given that MRI is an effective imaging tool, its role in the analysis of severe and anogenital HS lesions merits considerable attention. Unfortunately, anoperineal HS imposes diagnostic dilemmas. It has multiple symptoms and presentations and often mimics other diseases in the intertriginous areas. Therefore, a thorough understanding of HS is essential to avoid delayed diagnoses. This review highlights the typical MRI imaging features and staging of HS, emphasizing on the anoperineal location. The review also differentiates the disease from mimics to facilitate the prompt delivery of appropriate treatment and improve patients' quality of life.
