The aim of this study was to present a clinical case of chemodectoma located in the left atrium in a dog. Chemodectoma is a heart base tumor, neoplasms that occur in the proximity of major blood vessels. A presumptive diagnosis is made based on location and appearance of the tumor in echocardiography examination. In advanced diagnostics computed tomography (CT) and magnetic resonance imagining (MRI) are used. Final diagnosis is made mainly during autopsy based on histopatological examination or less commonly in veterinary medicine on a histopathological examination of the tissue taken during a biopsy or of the entire removed tumor. In literature few methods of treatment are presented, including surgery, chemotherapy and radiotherapy. In an 8-year-old male French bulldog a tumor in the left atrium was detected. The tumor filled almost the entire left atrium, additionally pericardial effusion and ascites were observed. For treatment, tarantula cubensis extract (Theranecron) was used. After the introduction of Theranecron the patient felt significantly better. Theranecron may be one of the possibilities of palliative therapy in the case of diagnosing inoperable chemodectoma.

Histopathological Subtype

Primary heterotopic meningiomas are lesions that are not associated with a cranial nerve foramen, vertebral canal, or intracranial structure. The most common histopathological subtype is meningeal epithelioma. In clinical practice, primary heterotopic nasal meningioma occurs relatively rarely, and its most common pathological type is psammomatous meningioma, whereas nasal fibrous meningioma is infrequent. In our case, a 31-year-old male patient was admitted to the hospital with “progressive nasal obstruction on the right side for half a year.” Computed tomography examination of the paranasal sinuses revealed a polyploid mass in the right nasal cavity. The patient underwent surgical resection of the mass under nasal endoscopy. Histopathological examination confirmed that the mass was an ectopic meningioma of the nasal cavity. The patient was regularly followed up for 2 years without recurrence of the tumor. Primary heterotopic fibrous meningioma of the nasal cavity is clinically rare but should be considered as a differential diagnosis for hemangioma of the nasal cavity, inverted papilloma, and nasal polyp. The final diagnosis is based on pathology and immunohistochemistry analysis results.

Schwannomas are neurogenic, benign, well circumscribed tumors arising from schwann cells. Schwann cells are neural originating cell. These are either sporadic or inherited with sporadic being most common. In about 3% of patients, association with neuro-fibromatosis 2 gene is documented. Primary mesenteric schwannoma is extremely rare with establishing a pre-operative diagnosis almost impossible. Imaging modalities including computed tomography as well as MRI fails to make a diagnosis due to the non-specific characteristics. Surgery is curative with histopathological examination and immunostaining establishing the final diagnosis post-operatively. Immunostaining helps in differentiating it from other conditions such as gastro-intestinal stromal tumors as well as malignancies. Rarity of this condition make this case report of a 32-year-old male unique.

Parotid Tumors

F.NA.C has been used for ages as a safe and economical tool for fast preoperative diagnosis of parotid tumors. It has certain pitfall which sometimes leads to misdiagnosis and consequently it may have affect on treatment of the tumors. Keeping in view of the diverse classification of parotid tumors’ information from cytology should be combined with radiology as well as clinical diagnosis. Aim: To discuss some cases where there was discrepancy between cytological diagnosis and histopathological result and also suggest measures to improve the efficacy of F.N.A.C. Material and methods: The study includes 50 cases of parotid tumours who presented to the  department of ENT at Government medical college Haldwani which is a tertiary referral centre during 2009 to 2016. Only adult patients were included and inflammatory swelling were excluded from the study. All patients evaluated  Contrast enhanced computerized tomography(CECT) and  Magnetic resonance imaging (MRI) followed by Fine needle aspiration cytology .Preoperative diagnosis was made upon the findings of the above investigations and different types of  parotid surgeries  were done. . Final diagnosis was made on  histopathological  examination. Result :The most common tumour  came out to be pleomorphic adenoma (23 cases-46%) followed by mucoepidermoid carcinoma(12cases-24%). In ten  cases there was no clear cut  association between cytological diagnosis and final histopathological diagnosis. Conclusion: FNAC is highly sensitive and specific technique for diagnosis of many salivary gland swellings. FNAC can be used preoperatively to avoid unnecessary surgery and biopsy. Details of clinical information and radiologic features may help the pathologist to arrive at the appropriate diagnosis and reduce false interpretation. Pitfalls may also occur with improper technique of FNAC which can be overcome by proper caution.

Coronary sinus aneurysm (CSA) is an extremely rare entity. Herein, we present an unusual case of an 18-year-old symptomatic female patient with a giant CSA. Secondary vena cava aneurysms were also manifested. The final diagnosis was confirmed by enhanced computed tomography (CT) and cardiac catheterization. As far as we know, it is the first case that such a giant CSA coexists with secondary vena cava aneurysms. Considering the complexity of postoperative reconstruction, we believe that heart transplantation may be the optimal way for treatment. The patient received anticoagulant due to the superior vena cava (SVC) thrombosis while waiting for a donor.

AbstractScopolamine is an alkaloid which acts as competitive antagonists to acetylcholine at central and peripheral muscarinic receptors. We report the case of a 41-year-old male convict with a 27-year history of cannabis abuse who suddenly died in the bed of his cell after having smoked buscopan® tablets. Since both abuse of substances and recent physical assaults had been reported, we opted for a comprehensive approach (post-mortem computed tomography CT (PMCT), full forensic autopsy, and toxicology testing) to determine which was the cause of the death. Virtopsy found significant cerebral edema and lungs edema that were confirmed at the autopsy and at the histopathological examination. Scopolamine was detected in peripheral blood at the toxic concentration of 14 ng/mL in blood and at 263 ng/mL in urine, and scopolamine butyl bromide at 17 ng/mL in blood and 90 ng/mL in urine. Quetiapine, mirtazapine, lorazepam, diazepam, and metabolites and valproate were also detected (at therapeutic concentrations). Inmates, especially when they have a history of drug abuse, are at risk to use any substance they can find for recreational purposes. In prisons, active surveillance on the management and assumption of prescribed drugs could avoid fatal acute intoxication.

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses with unknown cause. A 60-year-old man presented with sustained ventricular tachycardia. Transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated an expanding 73 × 40 mm sized calcified mass in the left ventricle. He underwent successful total removal of the mass and cryo-ablation at the normal myocardial border. Histopathological examination confirmed a diagnosis of cardiac calcified amorphous tumors. The postoperative course was uneventful, without ventricular tachycardia recurrence. To our knowledge, this is the first reported case of confirmed cardiac calcified amorphous tumors causing ventricular tachycardia and treated by surgical resection combined with cryo-ablation.

BACKGROUND: The therapeutic response to endobronchial tuberculosis is usually evaluated by bronchoscopy. Currently, there are no published studies investigating the use of computed tomography for the evaluation of therapeutic response in endobronchial tuberculosis.OBJECTIVE: A retrospective study was performed to evaluate the bronchoscopic and computed tomographic features of endobronchial tuberculosis before and after treatment. The aim of this study was to investigate the usefulness of computed tomography for the assessment of treatment.METHODS: The clinical, pathological and bronchoscopic features of endobronchial tuberculosis were evaluated in 55 patients. The age range of the patients was 21 to 52 years. Computed tomography and bronchoscopy were performed before and after treatment.RESULTS: Diagnosis of tuberculosis was confirmed by culture and histopathological examination. Bronchoscopic examination revealed 89 endobronchial lesions of various types in 55 patients. The exudative type was the most common. Follow-up bronchoscopy revealed that exudative-, ulcerative- and granular-type lesions healed completely. Computed tomography performed after treatment correlated well with the follow-up bronchoscopic findings.CONCLUSION: The results suggest that follow-up computed tomography is useful for the evaluation of therapeutic response and complications associated with endobronchial tuberculosis, and may replace bronchoscopy.

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
