A rare case of spontaneous nephrocutaneous fistula

Acute and chronic pyelonephritis are known afflictions to the kidney in diabetics and in patients of abnormal urinary anatomy. And its presentation as a spontaneous sinus opening on the anterior abdominal wall is a rare phenomenon. We present one such rare case of a 71-year-old male with pus discharge from the anterior abdominal wall for 7 months. On investigating, it was found to be a nephrocutaneous fistula arising from the left non-functional kidney. This was dealt with left nephrectomy along with excision of the sinus tract. Though a very rare condition, a possibility of nephrocutaneous fistula must be kept when dealing with discharging sinus in lumbar region.

A Rare Case of Infected Cervicodorsal Intramedullary Epidermoid Cyst

Introduction Intramedullary spinal epidermoid cysts have a reported incidence of less than 1% of intramedullary spinal cord tumors; and out of these, intramedullary epidermoid lesions within the cervical spinal cord are even rarer. Here, we present the case of an adult patient with an infected intramedullary epidermoid cyst, identified on magnetic resonance imaging (MRI) at the C7–D1 level that was successfully excised without any worsening of neurological status. Case Presentation A 23-year-old female patient presented with history of moderate degree intermittent fever followed by gradually progressive right-sided weakness. She had paresthesia below C5 dermatome on the right side. On close inspection of the back, a tiny sinus opening was noted at the D2 level near the midline. MRI of the spine showed an intramedullary lesion at the C6–D1 level with the tract connecting to the subcutaneous lesion. Somatosensory evoked potential (SSEP) monitoring was done during the surgery with near total excision of the lesion. Conclusion Even though the location is rare, a differential diagnosis of the epidermoid should always be considered. A tiny dermal sinus opening helped us in proper diagnosis, along with surgical excision, by providing us a direct path to the intramedullary lesion. An early diagnosis and treatment with neurophysiological monitoring helped us in the maximum safe resection of the lesion without developing any new deficit.

Fourth Branchial Pouch Sinus: A Report of 7 Cases and Review of the Literature

A fourth branchial pouch sinus often manifests quite late in life as a recurrent neck abscess, suppurative thyroiditis, or pseudothyroiditis. Demonstration of the sinus opening in the piriform fossa by hypopharyngoscopy in combination with ultrasonography of the neck provides adequate information to justify proceeding to surgery. The sinus tract usually courses through the thyroid cartilage. The most effective treatment is surgical excision of the tract up to the piriform fossa through the cartilage. This procedure is associated with very low complication and recurrence rates. A fourth branchial pouch sinus is an uncommon condition. Even so, it is still underdiagnosed as a result of poor awareness of its existence by medical practitioners, including otolaryngologists. Part of the reason is a lack of adequate coverage of this topic in otolaryngology and surgery textbooks. In this article, we add to the literature by describing our experience with 7 patients—4 males and 3 females, aged 5 to 45 years (mean: 25.6)—who were diagnosed with a fourth branchial pouch sinus over a 6-year period. The diagnosis was confirmed by identifying the sinus opening at the apex of the piriform sinus during hypopharyngoscopy. Definitive treatment consisted of surgical exploration of the neck and excision of the tract.

Virtual Mapping of the Frontal Recess: Guiding Safe and Efficient Frontal Sinus Surgery

Objective To define relationships between the frontal sinus opening, ostia of other frontal recess cells, and endoscopic landmarks and to develop a clinically useful framework to guide frontal sinus surgery. Study Design Retrospective review. Setting Tertiary care academic referral center. Methods Adult patients with computed tomography (CT) without sinonasal pathology were included. Virtual endoscopy (using OsiriX) and corresponding CT reconstructions were used to identify all visible ostia in the frontal recess and characterize their positions in spaces between the uncinate/agger nasi (U), bulla ethmoidalis (EB), and middle turbinate (MT). Results Two hundred sides in 100 patients (median age 51 years, 62% female) were analyzed. The “center” of each map was defined as the intersection of spaces between U, EB, and MT. The frontal sinus opening was in the “center” in 53% of frontal recesses, lateral to this position in 29%, and anterior in 11%. When the frontal sinus opening was at the “center,” anterior ostia drained frontal Kuhn T cells in 51% and intersinus septal cells in 23%. The skull base attachment of the apical strut of the uncinate process demarcated medial and lateral within the space between U and EB, with the opening to the frontal sinus medial in 68% and lateral in 31%. Left-right asymmetry in frontal sinus openings was noted in 46% of patients. Conclusion Combining preoperative imaging and knowledge of these anatomic relationships may facilitate more efficient frontal outflow tract identification and instrumentation. This represents the first and largest description of ostial configurations relative to endoscopic structural landmarks. Level of Evidence: 4
