Spontaneous pneumothorax is rarely reported in the cat. This case report describes the use of computed tomography (CT) to diagnose pulmonary bullae in an adult cat with recurrent spontaneous pneumothorax. A large bulla in the right middle lung lobe and several blebs in other lobes were identified by CT. Partial lobectomy of the right middle and right and left cranial lung lobes was successfully performed to remove the affected portions of lung. Histopathological examination suggested bronchopulmonary dysplasia (BPD) as the underlying cause for development of the pulmonary bulla. This is the first case report in the veterinary literature describing the use of CT to identify pulmonary bullae in the cat with BPD as a possible underlying cause.

Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined corticated border, whereas computed tomography revealed a unilocular radiolucent lesion and buccal expansion together with cortical perforation. The lesion was treated via enucleation and curettage of the marginal bone and fenestration. A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes. The patient’s postoperative course has been favorable up to now, and no marked changes have been observed. We presented a case of hybrid ameloblastoma and reviewed the 36 reported cases of hybrid ameloblastoma that have been reported in the English literature.

SUMMARY The paranasal sinus mucocele is an epithelized cystic lesion containing fluid and is characterized by non-neoplastic expansion of the paranasal sinus due to its capacity to erode the overlying bone. Etiology of these lesions is still under debate. In this report, we described a case of a patient with frontal recess mucocele, associated with contralateral frontal recess osteoma. A 55-year-old man was admitted to the Department of Otorhinolaryngology of our hospital with the complaints of a headache affecting the fronto-ethmoidal region, left-sided nasal obstruction, and postnasal discharge. Computed tomography (CT) scan of the paranasal sinuses showed a dense bony lesion in the left and a cystic hypodense mass in the right-sided frontal recess. The patient was treated surgically, with a combined endoscopicexternal approach, bilaterally. Histopathological examination showed that the wall of the cyst was mucocele, and the bony formation was osteoma. The frontal recess osteoma is regarded as the primary condition. Thus, better ventilation and drainage of the frontal sinus were reestablished.

Two cases of pulmonary vascular anomaly in unrelated adult alpacas ( Vicugna pacos) are described. In the first case, a 9-year-old intact male alpaca presented at Oregon State University Veterinary Teaching Hospital with bilateral epistaxis and died the subsequent day following severe hemorrhage from the mouth and nostrils. At necropsy, a tortuous vascular lesion was identified in the right cranial lung lobe, associated with hemorrhage into airways. In the second case, a 2-year-old female alpaca presented with postpartum anorexia, opisthotonus, and recumbency. In this second case, a similar vascular lesion was identified in the right cranial lung lobe but without associated hemorrhage. Histopathological examination of the lesion in both cases revealed numerous dilated, irregular blood vessels with marked variation in wall thickness within vessels, surrounded by foci of extramedullary hematopoiesis. Diagnoses of locally extensive pulmonary vascular anomalies (arteriovenous malformations) were made.

A 53-year-old woman presented with a spontaneous right-sided pneumothorax. Computed tomography chest scan demonstrated a large bulla involving the right middle lobe. Recurrence of the pneumothorax after initial closed chest tube drainage necessitated thoracotomy and wedge resection. Histopathological examination revealed features consistent with a benign mesenchymal cystic hamartoma. Pneumothorax is a recognized complication of mesenchymal cystic hamartoma, a lesion that also has malignant potential.

Abstract Gallbladder hernia through the foramen of Winslow is an uncommon condition and gallbladder hernia combined with volvulus is even rarer. A 70-year-old patient was hospitalized with the clinical signs of pain in the right hypochondriac region associated with fever. The computed tomography scan images showed some signs of gallbladder herniation through the foramen of Winslow. We decided to remove the gallbladder and found the gallbladder infundibulum twisted and necrotic. This was the first case of a male patient who suffered from gallbladder herniation with volvulus after three cases of female patients reported in the literature.

A three-year-old male British shorthair cat that had exhibited progressive lethargy and intermittent dyspnoea for 14 days was referred for evaluation of acute respiratory deterioration. Clinical findings included rapid and shallow breathing, pale mucous membranes, sound suppression on the right side, and a subcutaneous haematoma in the right epigastric area. Serum biochemistry analysis showed leukocytosis and thrombocytosis. Radiographs revealed hydropneumothorax, a broken eighth right rib, atelectatic right cranial lung lobe (RCrL), and consolidation of the right middle lobe (RML). Doppler examination revealed sonographic changes in the echotexture of both lobes and venous flow was absent in the twisted RML. Furthermore, bronchoscopy showed proximal narrowing of the cat’s RML bronchus. Exploratory surgery via medial sternotomy confirmed torsion of the RML and identified deteriorated gas-containing lesions in the collapsed RCrL. Both lung lobes were removed by standard lobectomy, and postoperative recovery was without major complications. Histopathological examination diagnosed multiple bullae and blebs, with significant subpleural haemorrhages in the atelectatic RCrL, whereas tissue congestion with haemorrhages, necrosis, and thrombosis typical for lung lobe torsion were observed in the RML. No other underlying aetiology was apparent. Two months post-operatively, the cat presented with similar acute onset of dyspnoea and spontaneous pneumothorax and was euthanised at the owner’s request. The autopsy revealed identical new emphysematous changes in the contra-lateral lung lobes that had been absent at the time of surgery. Emphysematous lesions, regardless of their origin, should be considered in the etiopathology of lung lobe torsion.

Background: Langerhans cell histiocytosis (LCH) is a term describing a clonal proliferation of pathologic Langerhans cells (histiocytes), which may manifest as unisystem (unifocal or multifocal) or multisystem disease. LCH is a rare cause of the orbital tumor with the predilection to its lateral wall which is particularly common in children. Case Description: We report an unusual case of a 33-year-old woman, 6 months after childbirth, who presented with the edema of the right orbit and upper eyelid with headaches. On physical examination, the patient had a right superior and lateral swelling of the eyelid and the orbit and right enophthalmos, without blurred vision. Magnetic resonance imaging showed well-defined, expansile, intensely homogeneously enhancing mass lesion in the right superolateral orbital rim with the destruction of the upper wall of the orbit, growing into the frontal sinus and frontal part of the cranium with the bold of the dura mater in this region. Radical excision of the tumor was achieved through a right fronto-temporo-orbito-zygomatic craniotomy. Histopathological examination had confirmed the diagnosis of the LCH. The patient was discharged home with a modified Rankin Scale score of 0. Conclusion: The main purpose of this case report is that LCH should be considered as one of the possible causes of quickly appearing tumor of the orbit in adults.

Co-infections or consecutive infections of mucormycosis and aspergillosis are very rare. Additionally, distinguishing between these two infections is also difficult as both these conditions have similar clinical features. We report two similar cases from Tamilnadu, who presented to a tertiary care centre in Puducherry, India in 2017 (first case) and 2019 (second case). The first case was a 70-year-old, non-diabetic male patient who presented with haemoptysis with a prior history of pulmonary tuberculosis. Computed tomography bronchial angiography revealed an air-crescent sign and the histopathological examination showed a fungal ball (aspergillus and mucor) in the right upper lobe and foci of fungal infection in the middle lobe. The second case was a 65-year-old diabetic male patient who presented with blackish expectoration and haemoptysis. A high-resolution computed tomography scan showed a reverse-halo sign in the right upper lobe. The results of the bronchoscopy-guided biopsy were consistent with a diagnosis of mixed mucormycosis and aspergillosis with angioinvasion. Both patients responded to amphotericin B with surgical excision of the affected lobe in the first case. A high degree of clinical suspicion, early surgical intervention and antifungal therapy are essential in the treatment of this rare co-infection.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

Isolated gall bladder tuberculosis (GBTB) is exceedingly rare even in an endemic region and is usually found as a GB mass in association with cholelithiasis. Confirmed preoperative diagnosis is very difficult, and most cases are diagnosed after cholecystectomy. We present a case of a 45-years-old woman who came with symptoms of chronic cholecystitis. Computed tomography scan revealed intraluminal gallbladder mass and cholelithiasis. The patient underwent open cholecystectomy and GBTB was diagnosed after histopathological examination. Histopathological examination should be done after all cholecystectomy operations. Faridpur Med. Coll. J. 2020;15(2): 106-107
