Kolkata: A sudden episode of severe breathing
difficulty in a teenage girl from Jharkhand initially appeared to be a case of
a serious respiratory infection. However, when her condition worsened rapidly
despite treatment, doctors at Manipal Hospital Broadway looked beyond the
obvious and identified a rare neurological emergency, Myasthenia Gravis leading
to Myasthenic Crisis, a condition where weakness of the muscles can severely
affect breathing. With timely diagnosis and coordinated intervention by Dr.
Debraj Jash, Director – Pulmonology, Manipal Hospitals Kolkata, and Dr.
Vaibhab Seth, Consultant – Neurology, Manipal Hospital Broadway, the
patient was successfully treated and recovered, highlighting the importance of
early recognition and a multidisciplinary approach in managing complex medical
emergencies.
The girl was referred to Manipal Hospital Broadway
from a railway hospital in the month of May with acute respiratory distress.
Her initial symptoms, along with CT scan findings, suggested pneumonia, and she
was started on intravenous antibiotics for a suspected severe lung infection.
However, within a few hours, her breathing difficulty increased significantly,
leading to respiratory failure and the need for mechanical ventilation support.
During further evaluation, doctors observed that the severity of her breathing
problem did not completely match the lung findings seen in her scans. While the
CT scan did not show extensive lung damage, the patient’s condition was rapidly
deteriorating. This difference between the test results and her clinical
condition prompted the medical team to investigate other possible causes.
A detailed assessment revealed significant muscle
weakness, including reduced ability to move, raising suspicion of an underlying
neuromuscular disorder. The team evaluated her for conditions including Myasthenia
Gravis and Guillain-Barré Syndrome. Further investigations confirmed that
she was suffering from Myasthenia Gravis with Myasthenic Crisis, which is
a rare autoimmune disorder affecting the communication between nerves and
muscles. In this condition, the body’s immune system mistakenly interferes with
the signals that nerves send to muscles, causing weakness that can worsen with
activity and improve with rest. While many patients experience symptoms such as
drooping eyelids, difficulty swallowing, or weakness in the limbs, in severe
cases the muscles responsible for breathing can also become weak. This can
result in Myasthenic Crisis, a life-threatening condition that may lead to
sudden respiratory failure and require intensive care support.
Speaking about the case, Dr. Debraj Jash, said, “The
patient came with severe respiratory distress, and the initial presentation was
very similar to pneumonia. However, her rapid deterioration and the mismatch
between her CT findings and clinical condition made us consider other possible
causes. In cases where respiratory failure cannot be fully explained by
lung-related problems, it is important to evaluate neurological conditions as
well, as the breathing muscles can also be affected. Early suspicion and
teamwork between different specialties helped us manage this challenging case
effectively.”
Following the diagnosis, the patient was immediately started
on intravenous immunoglobulin (IVIG) therapy, along with intensive monitoring
and supportive care. Under the continuous supervision of the Pulmonology,
Neurology, and Critical Care teams, she gradually improved, regained muscle
strength, was successfully weaned off mechanical ventilation, and was
discharged in a stable condition after 21 days of hospital stay.
Adding further, Dr. Vaibhab Seth, Consultant – Neurology,
Manipal Hospital Broadway, said, “Myasthenic Crisis is a severe and potentially
life-threatening complication of Myasthenia Gravis, an autoimmune neuromuscular
disorder where the communication between nerves and muscles becomes impaired,
leading to weakness of voluntary muscles. During a Myasthenic Crisis, the
weakness can suddenly worsen and affect the muscles responsible for breathing,
causing respiratory failure and the need for ventilatory support. In this case,
the major challenge was that the patient’s first and most severe symptom was
respiratory distress rather than typical neurological signs. Identifying the
condition early and starting appropriate treatment within a short period played
a key role in ensuring a positive outcome.”
Doctors at Manipal Hospital Broadway emphasized that
unexplained respiratory failure should not always be attributed only to
lung-related conditions. When a patient’s symptoms do not fully align with
initial investigations, considering alternative diagnoses, including
neurological disorders, can be crucial. Early diagnosis, timely treatment, and
collaboration among multiple medical specialties remain essential in saving
lives in rare and critical conditions like Myasthenic Crisis.
