History Of

A six-year-old, male, castrated European shorthair cat was presented due to a lifelong history of sneezing, nasal discharge, open-mouth breathing, stertor and vestibular problems. Clinical examination showed absence of airflow through the nostrils. Computed tomography of the head revealed an infiltrative soft tissue attenuating mass in the left nasal cavity, nasopharynx and the left frontal sinus. All of these locations could be successfully accessed through ventral rhinotomy and the mass was completely removed. Histological examination identified it as an inflammatory polyp. All respiratory and neurological symptoms disappeared, and two-and-a-half years after surgery, the cat was still without complaints.

AbstractA case of IgD myeloma in a 54-year-old male with a long-standing history of extramedullary plasmacytoma involving the larynx is reported.The patient was treated with radiation therapy and laryngectomy. Twelve years later, he complained of nasal bleeding. On examination he was found to have large masses in the left nasal cavity and in the left supraclavicular region. Histological examination of both lesions showed plasmacytoma. Serum immunoglobulin studies revealed an IgD monoclonal spike of the lambda type. Bence-Jones protein was present. Using the immunoperoxidase staining technique, cytoplasmic monoclonal IgD was detected.

Macroscopic Examination

A 13-year-old female spayed Domestic Shorthair cat presented with a history of right-sided mucopurulent nasal discharge for 18 months. Computed tomography revealed a mass within the right nasal cavity and the right frontal sinus. The animal was euthanized, and a postmortem examination was performed. On macroscopic examination, the right nasal cavity and the right frontal sinus were partially occluded by a soft whitish mass. Microscopically, the mass was composed of well-differentiated plasma cells that were immunopositive for immunoglobulin G and lambda light chains. These findings were consistent with a mature-type sinonasal plasmacytoma. In addition, there was right-sided mucopurulent rhinitis and sinusitis caused by a Pasteurella infection, which probably developed secondary to the sinonasal plasmacytoma. To the authors’ knowledge, this is the first report of a sinonasal plasmacytoma in a cat. The present communication shows that feline sinonasal plasmacytomas should be included in the differential diagnosis for tumors located in the upper respiratory tract of cats.

ABSTRACT A 6 yr old, spayed female, Rhodesian ridgeback was presented for a 6–8 wk history of serous nasal discharge after being quilled by a porcupine. Physical exam revealed mid dorsal maxilla sensitivity. Computed tomography showed a normal nasal cavity. Rhinoscopy revealed three porcupine quills which were removed from the nasal cavities. The patient’s clinical signs had improved dramatically at 1 wk follow-up. This case demonstrates the limitations of computed tomography for diagnosing intranasal porcupine quills and the importance of pursuing rhinoscopy in patients with clinical signs of nasal disease.

<p class="abstract">Actinomycosis is a rare anaerobic bacterial infection that presents in the form of cervicofacial, pulmonary, thoracic and abdominopelvic infections. It is usually caused by <em>Actinomyces israelii </em>which are a part of normal flora of aerodigestive tracts. They are opportunistic pathogens and cause infections which have odontogenic origin in oral cavity. Cervicofacial actinomycosis accounts for more than half of the cases and commonly affects the mandible. We are reporting a case of actinomycosis of left maxillary antrum presenting as a nasal polypi in a young man. He had presented with nasal discharge and yellowish crusts from left nasal cavity. Diagnostic nasal endoscopy revealed yellowish polypoidal mass arising from the left middle meatus. CT PNS showed soft tissue density mass measuring 3.7×4.3×4.1 cms in left maxillary antrum extending through and obliterating osteomeatal complex extending into left ethmoidal sinus. Patient underwent Functional endoscopic sinus surgery. The yellowish polypoidal mass in left nasal cavity was attached to the floor of the maxillary antrum by a thin stalk and had filled up the antrum. Histopathology of the specimen revealed inflammatory polyp with actinomycosis. Patient had an uneventful recovery and was put on long term antibiotics and regular follow up.</p>

An 11-year-old, spayed female keeshond was presented for unilateral epistaxis and serous nasal discharge of four weeks duration. Initial nasal radiographs, rhinoscopy, and histopathology suggested severe, destructive lymphoplasmacytic rhinitis. The patient deteriorated while receiving an anti-inflammatory dose of prednisone. A computed tomographic scan of the nose demonstrated a soft-tissue density in both the right nasal cavity and frontal sinus. Samples for histopathology obtained at surgery were diagnostic for nasal aspergillosis. All clinical signs resolved with a single, noninvasive infusion of intranasal clotrimazole and a four-week course of oral itraconazole.

Abstract Background The aim of this study is to evaluate additional findings which can be detected by post-contrast computed tomography (CCT) in relation to plain CT (PCT) findings in patients presented with head trauma. Medical records of canine patients with the history of head trauma from three institutions were reviewed. PCT- and CCT-anonymized images were evaluated by a veterinary radiologist separately. From the categorized findings the following conclusions were drawn as: abnormalities were identified on (A) PCT but missed on CCT, (B) CCT but missed on PCT, (C) both PCT and CCT. Results Thirty-two patients were included. The results showed that findings identified on CCT or PCT (category A and B) but missed on the other series were limited to mild soft tissue and sinus changes. Overall, 61 different fracture areas, 6 injuries of the temporomandibular joint (TMJ), 4 orbital injuries, 14 nasal cavities with soft tissue density filling, 13 areas of emphysema, 4 symphysis separations, 12 intracranial hemorrhages, 6 cerebral edema, 5 cerebral midline shifts, 3 intracranial aeroceles, 3 brain herniations and 6 intraparenchymal foreign bodies (defined as an abnormal structure located within the brain: e.g. bony fragments, bullet, teeth,..) were identified on both PCT and CCT separately (category C). Severity grading was different in 50% (3/6) of the reported cerebral edema using PCT and CCT images. Conclusion The results showed that PCT is valuable to identify the presence of intracranial traumatic injuries and CCT is not always essential to evaluate vital traumatic changes.

AbstractSinonasal malignant melanoma is rare and usually occurs in the nasal cavity. Presentation is often varied and occurs late in the natural history of the disease, resulting in a poor prognosis. A case is reported of a patient with malignant melanoma arising from the frontal sinus who presented with a forehead swelling and progressive confusion. A review of the literature on malignant melanoma in the nasal cavity and paranasal sinuses regarding its presentation, site of origin and principles of management is discussed.

We describe the case of a 65-year-old woman who presented with left nasal obstruction. Clinical and radiographic examinations revealed the presence of a soft-tissue mass that had obliterated the left nasal cavity. The mass was completely excised via an endoscopic approach. Histopathologic examination identified the tumor as an ossifying fibrosarcoma. The patient recovered uneventfully and remained free of disease at the 2-year postoperative follow-up. To the best of our knowledge, no case of an ossifying fibrosarcoma of the nasal cavity has been previously reported in the English-language literature. We discuss the features of this case and the clinical presentation, diagnosis, and management of fibrosarcomas of the nasal cavity and paranasal sinuses.

The aim of this study is to compare the delivery site of topical drugs using the short nozzle and the long nozzle. Fourteen fresh frozen cadaver heads were obtained. All cadaver specimens underwent bilateral endoscopic wide maxillary antrostomy, frontal sinusotomy, and complete sphenoethmoidectomy. The right nasal cavity of each cadaver was sprayed with radiolabeled saline using the short nozzle (short nozzle group), while the left nasal cavity was sprayed using the long nozzle (long nozzle group). The distribution of radioactive saline within the sinus cavities was determined using single-photon emission computed tomography/computed tomography. The distribution of the radiolabeled saline in reference with the maxillary line, vestibule, maxillary, ethmoid, sphenoid, and frontal sinus was compared between the 2 groups using Fisher exact test. The number of specimens that demonstrated radioactivity above the maxillary line is higher in the long nozzle group (14 cadavers, 100%) compared to short nozzle group (9 cadavers, 64.3%; p = .02). There are fewer specimens that demonstrated deposition of radioactive saline in the vestibule in the long nozzle group (6 cadavers, 42.86%) compared to short nozzle group (13 cadavers, 92.86%; P = .006). Compared to short nozzle group, there are more specimens demonstrating radioactivity in the maxillary, ethmoid, sphenoid, and frontal sinus in the long nozzle group, but the differences were not statistically significant ( p = 0.241, 0.347, 0.126, 0.5). Compared to short nozzle, long nozzle more frequently delivers intranasal drugs beyond the maxillary line and less frequently in the vestibule. These findings support the hypothesis that the use of long and narrow nozzle, instead of the conventional short nozzle, can improve sinonasal drug delivery in post-endoscopic sinus surgery nose.

Mucinous adenocarcinoma in association with chronic anal fistula is a rare case in clinical practice. The aim of this article was to report a rare case of anal gland mucinous adenocarcinoma in a patient who was treated in the Hospital of Kaunas University of Medicine. Case report. A 70-year-old male was treated for anorectal fistula in the surgical department. Four operations were performed for perineal abscess during the period of 15 years. During the period of 15 years, the patient complained of purulent secretion from the perineal abscess. After the last operation, anorectal fistula developed. Multiple biopsies and scrapings of the fistulous track were taken for histological examination. Histological examination revealed mucinous adenocarcinoma, G2. Subsequently, the patient underwent endoanal ultrasound, computed tomography scan, and colonoscopy. The computed tomography scan did not show pathology in the abdomen, but showed soft tissue induration at the site of anorectal fistula. Colonoscopy investigation did not show any pathology in the rectum and bowels. Endoanal ultrasound findings showed soft tissue induration at the site of anorectal fistula, no tumor in the rectum wall. The patient underwent abdominoperineal resection. Histological examination after abdominoperineal resection revealed anal duct mucinous adenocarcinoma pT2 N0 L0 V0 R0, G2. Metastases to the mesenteric lymph nodes were not detected. On the eight day after abdominoperineal resection, the patient was discharged from the hospital for follow-up. Summary. Mucinous adenocarcinoma in anorectal fistula is a rare condition. If surgical treatment for perineal abscess or anorectal fistula is not successful for a long time, mucinous adenocarcinoma should be suspected.
