Orocutaneous fistulas, or cutaneous sinuses of odontogenic origin, are uncommon but often misdiagnosed as skin lesions unrelated to dental origin by physicians. Accurate diagnosis and use of correct investigative modalities are important because orocutaneous fistulas are easily confused for skin or bone tumors, osteomyelitis, infected cysts, salivary gland fistulas, and other pathologies. The aim of this study is to present our experience with a patient with orocutaneous fistulas of odontogenic origin presenting as recurrent pyogenic granuloma of the cheek, and to discuss their successful treatment.

The case of a cyanotic infant with a rare combination of atypical pulmonary artery sling, imperforate anus, absence of the left kidney, interruption of the inferior vena cava, left side hemihypertrophy and diffuse-type pulmonary arteriovenous fistula is described. The clinical features were confusing, because of compounding abnormalities involving the respiratory tract and pulmonary circulation. The diagnostic approach to the etiology of cyanosis is discussed and the embryonic origin of pulmonary artery sling is reviewed.

A biliary fistula from the gallbladder can develop as a result of the erosion of stones into the surrounding viscera. An 82-year-old woman with multiple comorbid diseases presented with a persisting discharge from what was thought to be an abscess in the right hypochondrium, which had previously been drained. Sinogram confirmed fistulous communication with the gallbladder and gastric antrum. The fistulous tract was excised together with the gallbladder, and the gastric defect was repaired. The patient made an uneventful recovery.

PURPOSE: Clinical implementation of subtraction computed tomographic angiography (CTA) is limited due to motion artifact and/or long processing time. We evaluated the utility of a motion-corrected subtraction CTA technique for visualization of intra- and extra-cranial vascular lesions. MATERIALS AND METHODS: Pre- and post-contrast CT images were obtained in the target region of 53 consecutive patients which were consisted of 36 patients with 53 lesions and 17 normal patients. The source images were transferred to a personal computer (PC) and were automatically post-processed within one minute using novel motion-corrected subtraction CTA. The image quality of subtraction and non-subtraction CTAs was compared in each lesion category and lesion location using 3-point scale and Chi square test. RESULTS: The image quality of subtraction CTA was better than those from non-subtraction CTA (p<0.05) especially in the skull base lesions, such as carotid-cavernous fistulas, aneurysms in the cavernous internal carotid artery (ICA), and steno-occlusive lesions of the distal ICA, and extracranial lesions such as facial arteriovenous fistulas. CONCLUSION: The PC-based motion-corrected subtraction CTA technique allows fast generation of postprocessed images and can provide improved visualization of vascular anatomy and pathologies adjacent to bone in the skull base and head and neck areas.

Ureteroarterial fistula is an extremely rare complication, but is associated with a high mortality rate. Previous pelvic surgery, long standing ureteral catheter insertion, radiation therapy, vascular surgery and vascular pathology contribute the development of this uncommon entity. Herein, a case of ureteroarterial fistula in a 69-year-old female patient, who presented with a massive hematuria, proven in a second attempt at angiography, is reported.

Perianal abscess and fistula are 2 distinct entities that share a common pathology. A horseshoe fistulous abscess, a complex type of these conditions, occurs when the suppurative inflammation spreads through the deep anal space to the bilateral ischiorectal fossae. Following the intersphincteric plane, this infection may extend to the pararectal space, forming a supralevator abscess. We present a very rare case involving a 52-year-old male patient who was admitted to our surgical department with an extraperitoneal purulent inflammation as a complication following multiple drainage procedures for a posterior horseshoe abscess. Emphasis is given to the anatomical and technical considerations of eradication of anorectal sepsis and the management of complex fistula-in-ano along with a concise review of the literature.
