Cystic Hamartoma

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.

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.

Pulmonary carcinoids originate from neuroendocrine cells of the lung and comprise 0.5%–5% of all lung malignancies. Endobronchial carcinoids are rare, low-grade malignant tumors that occasionally coexist with other infectious diseases, including tuberculosis and nontuberculous mycobacterial infection. We treated a 63-year-old woman who presented with a right middle lobe obstruction. A chest computed tomography scan demonstrated a mass-like lesion in the right middle lobe with mediastinal lymphadenopathy. She underwent an exploratory operation after 2 weeks of antibiotic treatment. The pathology revealed a right middle lobe bronchial carcinoid tumor and aspergillosis. Chest computed tomography scans have revealed no recurrence of the carcinoid or aspergillosis during the 5-year follow-up.

OBJECTIVES: This study aims to trace the dynamic lung changes of coronavirus disease 2019 (COVID-19) using computed tomography (CT) images by a quantitative method. METHODS: In this retrospective study, 28 confirmed COVID-19 cases with 145 CT scans are collected. The lesions are detected automatically and the parameters including lesion volume (LeV/mL), lesion percentage to lung volume (LeV%), mean lesion density (MLeD/HU), low attenuation area lower than – 400HU (LAA-400%), and lesion weight (LM/mL*HU) are computed for quantification. The dynamic changes of lungs are traced from the day of initial symptoms to the day of discharge. The lesion distribution among the five lobes and the dynamic changes in each lobe are also analyzed. RESULTS: LeV%, MLeD, and LM reach peaks on days 9, 6 and 8, followed by a decrease trend in the next two weeks. LAA-400% (mostly the ground glass opacity) declines to the lowest on days 4–5, and then increases. The lesion is mostly seen in the bilateral lower lobes, followed by the left upper lobe, right upper lobe and right middle lobe (p < 0.05). The right middle lobe is the earliest one (on days 6–7), while the right lower lobe is the latest one (on days 9–10) that reaches to peak among the five lobes. CONCLUSIONS: Severity of COVID-19 increases from the day of initial symptoms, reaches to the peak around on day 8, and then decreases. Lesion is more commonly seen in the bilateral lower lobes.

SummaryOccipital neuralgia is a type of chronic headache disorder in the dermatomes of the greater or lesser occipital nerve. (7) We describe here a rare case of occipital neuralgia caused by an intramuscular lipoma. A 45 year-old man presented with troublesome pain in the occipital area with 3 x 2 cm palpable mass in the right occipital region. Patient was treated by a neurologist. The X ray for cervical vertebrae and computed tomography was performed.Computed tomography revealed a mass reminding intramuscular lipoma. Surgical management was indicated. During the operation stretching of the lesser occipital nerve was detected. After resection of lipoma on postoperative follow – up, the patient reported that the pain had resolved. During the histopathological examination, lipoma was confirmed.

Introduction Alveolar adenoma belongs to the group of benign epithelial tumors. Histogenesis of alveolar adenoma is a combination of proliferation of alveolar pneumocytes and fibrous tissue originating from septal mesenchyma. Case outline A sixty-nine-year old female patient was hospitalized for clinical examination and surgery of well defined and homogenous timorous lesion in the right middle lobe causing pleural pain. Bronchoscopic examination with biopsy did not resolve etiology of the disease. Tumorectomy was performed. Timorous nodule had a multicystic appearance and histologically, histochemically and immunohistochemically, an alveolar adenoma was estimated. Five years after surgery, the patient feels well, without respiratory symptoms and signs of recurrence or malignant alteration, respectively. Conclusion Alveolar adenoma is a rare benign lung tumor, most frequently presented as a solitary pulmonary nodule. After complete surgery, the tumor neither relapses nor malignantly alters. Surgical excision is curative. It is necessary to take into consideration alveolar adenoma, too, when a solitary pulmonary nodule is diagnosed.

BackgroundNecrotizing pneumonia and hyperleukocytosis, to the extent of that seen in leukaemia, is a rarely reported presentation. The commonest trigger of such a presentation is an inflammatory process caused by an overwhelming infection which leads to bone marrow irritation. However, the misdiagnosis of this clinical entity as leukaemia should be avoided at all costs so as to avoid the anxiety associated with a diagnosis of cancer, both to the patients and their families.Case presentationHere, we report the case of a 22-month-old boy who was referred to our Pediatric Oncology Unit (POU). Owing to a high total leukocyte count (TLC) of 98,000 cells/µl, there was a strong suspicion of leukaemia. The boy had been reviewed at another hospital where he presented with fever and cough refractory to the commencement of tuberculosis medications as a result of chest radiography findings. Laboratory investigations performed on admission in the POU were negative for leukaemia and other myeloproliferative disorders. A chest computer tomography (CT) scan was performed to delineate opacification in the right middle lobe. This revealed multiple necrotic and emphysematous foci in line with a diagnosis of necrotizing pneumonia. Subsequently, the patient responded well to a course of piperacillin- tazobactam. The TLC normalized and the cough and fever resolved over a period of 2 weeks. ConclusionHere, we describe a particularly rare case of leukaemoid reaction with a massive leukocyte count. Such patients can be easily misdiagnosed as having leukaemia or other myeloproliferative disorders, especially in settings with limited diagnostic availability. Such misdiagnosis can cause undue stress on the patient and their families. Thus, it is important that patients presenting with these symptoms should undergo a thorough review of history, physical examination and a structured workup.

Abstract Introduction: Lobar torsion is a rare but fatal complication, with such cases being mostly treated with pulmonary resection. Only a few cases of pulmonary torsion following esophagectomy have thus far been reported, and all cases occurred subsequent to transthoracic esophagectomy. Case presentation: We herein present the case of a patient with the right middle lobe torsion after thoracoscopic esophagectomy in a 64-year-old male.As the patient exhibited a hemodynamically unstable condition immediately after surgery and bronchoscopy and computed tomography revealed right middle lobe torsion, urgent surgery was performed.As torsion of right middle lobe was confirmed during a second operation, repositioning for torsion was performed. Fortunately, right middle lobe was aerated and exhibited a good complexion immediately after repositioning; therefore, pneumonectomy was not performed. Conclusion: Because it is difficult to observe the process of reinflation of a collapsed lung under direct vision in order to prevent lobar torsion when performing thoracoscopic esophagectomy, it is imperative to confirm the patency of the proximal bronchi during the operation using bronchoscopy.
