Ovarian Dermoid Cyst

Dermoid cysts are thought to be slow-growing tumors. This case series provides 2 clinical examples of sizeable growth of benign ovarian dermoid cysts in premenopausal patients. These patient cases were imaged initially; however, adnexal masses were not present on computed tomography images of the pelvis. Follow-up examination with sonography did demonstrate the presence of sizeable adnexal masses, which were confirmed by histology to represent benign dermoid cysts. Therefore, it may be wise to still consider ovarian dermoid cyst in the differential diagnosis in the setting of an adnexal mass that demonstrates the sonographic characteristics of a dermoid, even when absent on prior recent examinations.

Abstract Background Left ventricular assist devices (LVADs) are increasingly used in the treatment of end-stage heart failure. One important limitation in the follow-up of these patients is the very difficult echocardiographic image, because of the interposition of implanted materials. Case summary  We present here a case series of LVAD patients with severely limited transthoracic echocardiographic windows in whom the echocardiographic analysis of the left and right ventricular function could be obtained from a very unusual approach, using a right intercostal transhepatic window, allowing visualization of the heart chambers and quantification of function even in these very challenging cases. In one case, the result was confirmed by computed tomography. In the second case, computed tomography images were unreliable because of strong artefacts from the LVAD system and implantable cardioverter-defibrillator leads, but the transhepatic approach still provided sufficient image quality in order to allow the imaging follow-up of the patient. In the third case, the transhepatic window was the only approach that provided echocardiographic images, and due to the good visualization of the heart cavities, this imaging technique was considered sufficient for follow-up studies in this stable subject with LVAD as destination therapy. Discussion  The transhepatic window may represent a good alternative in selected LVAD patients with very difficult acoustic access in traditional transthoracic views. Modified or alternate echocardiographic windows may reduce the need for invasive procedures (transoesophageal echocardiography) or imaging methods using radiations.

<p class="abstract"><span lang="EN-US">Chondroid syringomas are uncommon cutaneous neoplasms of sweat gland origin which are slow-growing, nontender, subcutaneous or intracutaneous in location and often occurring in the head and neck region. Chondroid syringoma should be considered in the differential diagnosis of any subcutaneous nodule over the face. The clinician may miss the diagnosis of this lesion and if it is suspected, tumour should be excised with a margin of normal tissue and regular follow up should be done.</span></p>

Traumatic operative injury of the optic nerve in an endoscopic sinus surgery may cause immediate or delayed blindness. It should be cautioned when operating in a sphenoethmoidal cell, or known as Onodi cell, with contact or bulge of the optic canal. It remains unclear how frequent progression to visual loss occurs and how long it progresses to visual loss because of a diseased sphenoethmoidal cell. Research to discuss these questions is expected to help decision making to treat diseased sphenoethmoidal cells. From July 2001 to June 2017, 216 patients received conservative endoscopic sinus surgery without opening a diseased sphenoethmoidal cell. We used their computed tomography images of paranasal sinuses to identify diseased sphenoethmoidal cells that could be associated with progression to visual loss. Among the 216 patients, 52.3% had at least one sphenoethmoidal cell, and 14.8% developed at least one diseased sphenoethmoidal cell. One patient developed acute visual loss 4412 days after the first computed tomography. Our results show that over half of the patients have a sphenoethmoidal cell but suggest a rare incidence of a diseased sphenoethmoidal cell progressing to visual loss during the follow-up period.

AbstractObjectives:To analyse the radiological features of the bony nasolacrimal duct before and after functional endoscopic sinus surgery, and document the incidence of surgically induced dehiscence.Methods:A retrospective case series analysis was conducted of 63 consecutive patients who underwent uncinectomy as a part of 118 functional endoscopic sinus surgical procedures. All patients underwent pre- and post-operative computed tomography scans. Axial computed tomography images at the level of maxillary sinus were evaluated for the presence of bony nasolacrimal duct dehiscence, osteitis and completeness of uncinectomy.Results:The rate of nasolacrimal duct dehiscence prior to surgery was 6.8 per cent (8 out of 118 cases). Nasolacrimal duct dehiscence as a consequence of surgery was observed in 3.3 per cent of cases (4 out of 118), with a further 4.2 per cent (5 out of 118) showing post-operative reactive bony change of the nasolacrimal duct in the absence of dehiscence.Conclusion:The incidence of nasolacrimal duct injury observed was much lower than that previously reported in the literature.

Lipoma of the pancreas is a rare benign tumour which is usually discovered incidentally on imaging. We present a case of an incidentally discovered pancreatic lipoma in a 79-year-old man with non-metastatic prostate adenocarcinoma who was referred to radiology for follow-up imaging. Fat-containing tumours originating from the pancreas are very rare. Most lipomas show characteristic features on imaging that allow their differentiation. We present the imaging features of a pancreatic lipoma on ultrasound, CT and MRI, discuss the differential diagnosis, and provide a brief review of the literature.

Aim: Coronavirus disease 2019 is a life-threatening disease and how to improve survival of the patients is of great importance. Objective: To determine whether tocilizumab (TCZ) shows favorable results in coronavirus disease 2019 patients. Materials & methods: A retrospective study of four patients who received TCZ was conducted from 19 February to 31 March 2020 at Leishenshan Hospital, Wuhan, China. Clinical data of patients were compared before and after the administration of the agent. Results: There was not much difference in the clinical feature improvements and computed tomography images after TCZ administration in two mild patients. The other two severe patients died of disseminated intravascular coagulation and acute respiratory distress syndrome, respectively. Conclusion: Administration of TCZ was not shown a favorable outcome in this preliminary uncontrolled case series.

Abstract This report describes a patient with COVID-19 who developed spontaneous pneumothorax and subpleural bullae during the course of the infection. Consecutive chest computed tomography images indicated that COVID-19-associated pneumonia had damaged the subpleural alveoli and distal bronchus. Coughing might have induced a sudden increase in intra-alveolar pressure, leading to the rupture of the subpleural alveoli and distal bronchus and resulting in spontaneous pneumothorax and subpleural bullae. At the 92-day follow-up, the pneumothorax and subpleural bullae had completely resolved, which indicated that these complications had self-limiting features.

Oesophageal Duplication Cyst

A 7-year-old intact male Rottweiler dog was evaluated for recurrent dysphagia and regurgitation. Physical examination was unremarkable and routine blood works were within normal limits. Computed tomography revealed a defined lesion in the caudal mediastinum arising from the oesophagus. The lesion was excised using intercostal thoracotomy and the histological diagnosis was oesophageal duplication cyst. The dog recovered uneventfully and at a 3-year follow-up no clinical signs were reported. Although extremely rare, oesophageal duplication cysts should be considered in the differential diagnosis in cases of chronic regurgitation and dysphagia associated with evidence of an oesophageal lesion.
