Laryngeal schwannoma masquerading as malignancy.

Laryngeal schwannoma is a rare type of neurogenous tumour with a non-specific presentation. We present a case of a middle-aged man with issues of hoarseness, globus sensation and intermittent episodes of throat pain. The Hopkins examination showed right vocal fold irregularity with fullness in the right ventricle. The contrast-enhanced CT neck revealed an ill-defined lesion with contrast uptake extending into the paraglottic region with no neck node involvement. Considering the clinical presentation of hoarseness, throat pain and globus with imaging revealing contrast enhancement of lesion, direct laryngoscopy and biopsy were planned to rule out malignancy. Intraoperatively, a well-defined submucosal capsulated swelling became apparent after incision and dissection of the mucosa over the right vocal fold. A complete excision of the swelling was done with microlaryngeal instruments without tracheostomy. The histopathological report was suggestive of schwannoma. The literature review discusses clinical presentation, location, imaging features and management strategy.

Neck lump evaluation and pseudoaneurysm.

Pseudoaneurysm is the formation of a sac due to damage in the continuity of the arterial wall. Iatrogenic carotid artery aneurysm is a rare, life-threatening complication following fine needle aspiration (FNA). We are presenting here a case of pseudoaneurysm following FNA with a literature review.

Sigmoid sinus diverticulum without pulsatile tinnitus occurring concurrently with chronic otitis media mucosal type.

Sigmoid sinus diverticulum is a rare vascular anomaly often associated with pulsatile tinnitus. It can occur in cases of chronic otitis media squamous type (unsafe type) due to dehiscence of the sigmoid sinus plate caused by cholesteatoma. The presentation of which is that of pulsatile tinnitus. However, we present an unusual case of sigmoid sinus diverticulum occurring concurrently with chronic otitis media mucosal type (safe type) but in the absence of pulsatile tinnitus. This case report highlights the diagnostic challenges and management of this rare clinical scenario.

Retained foreign body in nose following eye injury.

A man in his 60s presented with diminution of vision of the left eye with nasal bleeding after accidental fall. On examination his left upper eyelid was lacerated and left temporal sclera was punctured which was repaired under local anaesthesia after which he was discharged by ophthalmologists but continued to complain of pain and left nasal obstruction. A non-contrast CT of paranasal sinuses revealed fracture of medial wall of left orbit, left ethmoid haemosinus and a metallic foreign body (FB) in the septum and anterior face of sphenoid. Diagnostic nasal endoscopy performed to remove the metallic FB showed plastic splinters embedded in the mucosa of nasal cavity which was unexpected. Hence, the FB was removed in two sittings because of diagnostic dilemma.

Silent threat of isolated sphenoid sinus tuberculosis resulting in blindness and ophthalmoplegia.

A diabetic woman in her fifties presented with a sudden onset of failing vision and diplopia involving the right eye for two days, along with fever and headache. Radiological investigations revealed right sphenoid sinusitis along with inflammation around the right orbital apex and optic nerve. Functional endoscopic sinus surgery, with orbital and optic nerve decompression improved the ocular movements, but not the visual acuity. Histopathology was suggestive of a granulomatous inflammatory lesion, and high-resolution computed tommography (HRCT) of the thorax revealed lung lesions suggestive of an old tubercular infection, and antitubercular treatment (ATT) was then initiated.At the end of two months of ATT, there was complete resolution of ophthalmoplegia, relative afferent pupillary defect, direct and consensual light reflex however, failure of improvement in her visual acuity, indicated damage to the optic nerve.Extrapulmonary tuberculosis involving an isolated sphenoid sinus is rare and elusive. Prompt radiological investigations, followed by orbital decompression and ATT, provide the best possible outcomes.

Disseminated nocardiosis presenting as a superinfected thyroglossal duct cyst in a patient with diabetes.

We introduce the case of a male patient in his 60s who was admitted to our emergency department with a persisting sore throat for the last 3 weeks and dysphagia. Fibre-endoscopic evaluation revealed an asymmetry at the base of the tongue. In combination with elevated white cell count and C reactive protein, a computerized tomography showed a superinfected thyroglossal duct cyst. Intravenous antibiotics were initiated, and the patient was taken to the operating room for cervicotomy. The microbiological swab taken intraoperatively detected Nocardia paucivorans Additional imaging revealed disseminated nocardiosis with cerebral and pulmonary manifestations.The patient was treated with oral trimethoprim/sulfamethoxazole and, over time, showed complete remission of central nervous system lesions and improvement of pulmonary involvement. Following this, the treatment was stopped 8 months after the initial diagnosis. In this report, we discuss treatment standards and outcomes of nocardiosis based on our management strategies of our patient.

Laryngeal stridor in children caused by reversible metabolic disease.

We report a case of a boy in his middle childhood who presented with inspiratory stridor and lactic acidosis and was subsequently diagnosed with partial biotinidase deficiency. Fibreoptic laryngoscope showed paradoxical vocal fold mobility.Partial biotidinase deficiency is an inherited disorder in which the body is unable to recycle the vitamin biotin. It may result in clinical consequences and can be easily treated with biotin but need a high index of suspicion to diagnose. The main symptoms include ataxia, seizures, hypotonia, psychomotor retardation, alopecia, skin rash, progressive deafness, optic atrophy and life-threatening episodes of metabolic acidosis. Laryngeal stridor is an uncommon presentation, but it is reversible in case of biotinidase deficiency. Invasive procedure like tracheostomy has not been shown to enhance outcomes.

Intrathyroidal thymic carcinoma.

A young woman in her early 30s presented with a right thyroid mass and progressive hoarseness due to a right vocal cord palsy. The preoperative fine-needle aspiration cytology was classified as Bethesda V and she underwent a total thyroidectomy and neck dissection. Intraoperatively, the thyroid mass was adherent to the oesophagus, trachea and encasing the right recurrent laryngeal nerve which was sacrificed. Final histopathology diagnosed a rare subtype of thyroid cancer known as intrathyroidal thymic carcinoma (ITC). She was then sent for adjuvant radiotherapy after a multidisciplinary tumour board discussion. This case report highlights the difficulty in preoperative diagnosis of ITC and the importance of immunohistochemical staining in clinching the diagnosis. In view of its rarity, there have been no published consensus on the treatment of ITC, hence we would like to share some learning points through a comprehensive literature review.

Stridor and severe subglottic stenosis: emergency tracheostomy for a neonate with a pinhole trachea.

Congenital subglottic stenosis is a rare but potentially catastrophic condition. In this report, we describe the management of a term neonate who was noted to have biphasic stridor during preassessment for correction of an imperforate anus at 26 hours of life. The neonate was found to have a pinhole trachea secondary to congenital subglottic stenosis. It was impossible to pass an endotracheal tube, so the neonate underwent an emergency surgical tracheostomy with a good outcome. A high index of suspicion led to appropriate steps being taken to safely anaesthetise the neonate.

Confronting multidrug-resistant Klebsiella meningitis after mid-clival Cerebrospinal Fluid leak repair: a therapeutic odyssey.

A man in his 40s with type 2 diabetes mellitus had persistent right-sided watery nasal discharge for 6 months following cerebrospinal fluid (CSF) leak repair at another hospital, prompting his visit to us due to recurring symptoms. Imaging revealed a CSF leak from the mid-clivus for which revision endoscopic CSF leak repair was done. Regrettably, he developed postoperative meningitis caused by multidrug-resistant (MDR) Klebsiella pneumoniaeManaging this complex case was a challenging task due to the pathogen's resistance to conventional drugs and the scarcity of scientific evidence. We initiated a culture-guided combination regimen with ceftazidime, avibactam, aztreonam and tigecycline. This decision stemmed from meticulous literature review and observed antibiotic synergy while testing for this organism.After 4 weeks of vigilant treatment, the patient's symptoms improved significantly, and CSF cultures were sterile. We present our approach to effectively confront and manage a challenging instance of postoperative MDR bacterial meningitis.

Treatment of congenital melanocytic naevi of nose using multiple flaps in single stage in a paediatric patient and literature review.

A girl in her middle childhood presented to the outpatient department (OPD) with a congenital melanocytic naevi (CMN) of the right nasal alar lobule. Her parents had aesthetic concerns and expressed their desire to get the lesion removed. The full-thickness excision of CMN was performed with the reconstruction of the defect using the nasolabial and dorsal nasal advancement flap with conchal cartilage to shape the contour of the ala.

Large atypical lipomatous tumour of the neck with mediastinal extension managed by transcervical excision.

Tumours of adipose tissue origin are relatively rare in the head and neck. Here, we report a case of an unfamiliar lipomatous lesion that involved the neck and mediastinum. A nil-comorbid man in his 40s presented with a slowly progressive anterior neck swelling of 3 years, which was diagnosed as lipoma by histopathological sampling. Computed tomography demonstrated the lesion to be involving parapharyngeal and retropharyngeal spaces with mediastinal extension. The lesion was removed by the transcervical approach. The final histology of the excised specimen, with immunohistochemistry for mouse double minute 2 (MDM2) and p16, suggested an atypical lipomatous tumour (ALT). This report accentuates the occurrence of this rare neoplasm in the neck, which often mimics lipoma clinically. Although radiology can demonstrate suggestive features, histology with MDM2 and/or p16 positivity can confirm the diagnosis of ALT as against the lipoma. A successful transcervical excision, despite the deeper extension of the lesion between the critical structures of the neck and mediastinum, demonstrates the non-infiltrating nature of the tumour.

Congenital cystic neck mass of thymic origin.

Neck masses are frequently seen in children. The differential diagnosis includes infectious, congenital and neoplastic lesions. We report a case of rare thymic neck mass in a boy in his middle childhood presented with a history of a left anterolateral neck mass not associated with fever, dysphagia or shortness of breath. The radiographic evaluation showed a picture of a thymopharyngeal duct cyst. Thymic remnant and thymopharyngeal duct cyst are caused by the failure of obliteration and might appear as a lateral neck mass in children. The most effective treatment for a thymopharyngeal duct cyst is total surgical excision. This particular case highlights the importance for clinicians to have a high index of suspicion for a broad differential diagnosis when evaluating paediatric patients who present with neck mass. Additionally, we emphasise the importance of consistently considering thymopharyngeal cyst as differential diagnosis.

Tracheal metallic hybrid stent removal via tracheostomy: an unconventional approach.

Increasing use of tracheal expandable metallic hybrid stents will lead to common encounters with these devices in emergency airway management. The presence of these stents qualifies any patient as a challenge when an emergency tracheostomy is needed. We report an unorthodox technique of tracheostomy with concomitant removal of tracheal stent, without any major complications. Although the combined approach with bronchoscopy and tracheostomy has been reported in similar cases, we present a safe procedure when rigid bronchoscopy is not available.

Complicated penetrating foreign body neck injury.

Penetrating neck injury is associated with significant morbidity due to the several structures (neurological, vascular and aerodigestive) within close proximity to one another. This case highlights an uncommon presentation of an embedded foreign body following penetrating neck trauma and the decision-making required during management.

Tumescent solution: a game changer in excising refractory arteriovenous malformation.

Arteriovenous malformations of the head and neck are rare and inborn errors of vascular morphogenesis. They pose therapeutic challenges owing to their bleeding tendency and a high chance of recurrence. Treatment modalities include digital subtraction angiography with embolisation as a primary treatment or can be done preoperatively followed by surgical excision. We present a case of recurrent arteriovenous malformation of the postauricular region in an adolescent male who was taken up for upfront surgical excision with the help of a tumescent solution, thereby eliminating the need for embolisation and drastically reduced intraoperative blood loss.

Varicella mimicking complications of acute rhinosinusitis in an infant.

Varicella is the manifestation of primary infection with the varicella-zoster virus, mainly affecting preschool and school-aged children. The children suffer from a generalised, vesicular rash and fever. Despite the infection's typically non-threatening course, a variety of severe complications have been described.The authors present the case of a female infant suffering from varicella and developing preseptal cellulitis with a frontal abscess while being treated with intravenous antibiotics. Otorhinolaryngology consultation was sought since the clinical image was highly suggestive for sinusitis complications, namely orbital cellulitis and frontal bone osteomyelitis (Pott's puffy tumour). However, the child was below the age of frontal sinus development and there was no other apparent sign of sinonasal involvement. Ultrasonography revealed a mid-frontal collection without signs of abscess formation preseptally or postseptally, leading to the diagnosis of cutaneous superinfection of varicella lesions. The frontal abscess was drained, and the child fully recovered under antibiotic treatment.
