ABSTRACT
Introduction:
Mediastinal masses in the paediatric population pose a challenge for diagnosis and acute management especially when they present with compression of mediastinal structures.Objectives:
To study clinical, radiological, and pathological characteristics, treatment, complications, and outcome of patients with mediastinal masses admitted to IPCU with emphasis on respiratory support provided. Materials andmethods:
Retrospective analysis of medical records of patients admitted with mediastinal masses between 1st July 2020 and 31st October 2021 in PICU at B.J.Wadia Hospital for Children.Results:
10 patients (6 months to 16 years) were included. The common presenting symptoms were breathlessness (90%), orthopnea (44%), cough (40%), fever (40%), and weight loss (20%). One patient had superior vena cava syndrome, 50% had hepato-splenomegaly/lymphadenopathy. One patient was diagnosed outside as a yolk sac tumour and referred. Three patients were wrongly treated as TB before they were referred. The average duration of symptoms before presenting to the hospital was 82.7 days. Airway compression was seen on a CT scan in 6/10 patients. Mechanical ventilation was required in 6 patients and non-invasive ventilation in three. The mean duration of mechanical ventilation was 13.1 days. All the patients required PEEP >7 cm H2O, propped up position, and intermittent desaturations requiring an increase in ventilator settings for a short duration of time or use of paralytics/sedation boluses. Difficult intubation was encountered in 2 patients of whom a smaller size tube was used in 1 patient. Bronchoscopy, LMA insertion was not required in any. Tissue for diagnosis was obtained by CT-guided or USG-guided LN biopsy. 80% needed a mediastinal mass biopsy. During the biopsy, procedural sedation was done using drugs propofol or ketamine which was well tolerated. CT-guided retroperitoneal lymph node biopsy was inconclusive in 1 patient and eventually required open inguinal lymph node biopsy. Final diagnoses included T cell ALL in 2 patients, AML, classical Hodgkin's lymphoma, neuroblastoma, alveolar rhabdomyosarcoma, yolk sac tumour, teratoma, tuberculosis, in single cases. Definitive diagnosis could not be confirmed in 1 child though blood EBV PCR came positive (viral copies >105 copies/mL) after the child expired. The mean time from symptom onset to diagnosis was 90 days. The mean time from presentation to diagnosis was 7.2 days. The mean duration of IPCU stay was 15.8 days. Patient with yolk sac tumour was COVID-19 positive who later developed peripheral digit gangrene. 7 patients received chemotherapy, 1 patient received AKT and one underwent surgical resection of tumour. Complications encountered were AKI (10%), TLS requiring hemodialysis (10%), and chylothorax (10%). Mortality was 50% of whom 2 did not respond to chemotherapy and 3 had intercurrent events. 5 children were discharged from the unit.Conclusion:
At our centre, mediastinal masses are frequently malignant in origin. Though TB is common in our country, not all mediastinal masses are TB. All the effort should be made to obtain microbiological/tissue diagnosis before initiating the treatment. Intubating and ventilating a mediastinal mass is a challenging task and those who require intubation have a poor prognosis. Late diagnosis and associated poor prognosis are glaring, prompting for early intervention to improve outcome.
