Multisystem Imaging Features of Tuberous Sclerosis Complex: The First Case Series from Somalia with a Comprehensive Literature Review

Imagine a condition where the body's natural growth controls malfunction, causing harmless but disruptive clumps of tissue to form in the brain, skin, kidneys, and other organs. This is the reality for people living with a rare genetic disorder known as tuberous sclerosis complex. The name comes from the way these clumps, called tubers, feel like hard potatoes when they form in the brain. While the condition affects people of all backgrounds, it often goes unnoticed in places where advanced medical testing is scarce. Without the ability to analyze a patient's DNA, doctors in these regions face a difficult challenge: how to confirm a diagnosis and start the right care when the most definitive tools are out of reach. The question becomes whether the visible signs of the disease, seen through the eyes of a skilled clinician and the lens of a camera, are enough to tell the whole story.

In a new report from Somalia, researchers have provided a clear answer to that question by documenting the first known cases of this disorder in the country. The team, working at a hospital in Mogadishu, followed two patients who showed the classic signs of the disease but could not undergo genetic testing. Instead, they relied on a combination of detailed physical exams and medical imaging to reach a confident diagnosis. Their work demonstrates that even without a genetic test, doctors can identify the condition with certainty by looking for specific patterns in the brain and body, offering a vital path forward for patients in resource-limited settings.

The first patient was a five-year-old girl who had been struggling with seizures that did not respond to standard medication. Her story began when she was three, marked by episodes of sudden, uncontrollable crying or laughing, followed by full-body convulsions. Beyond the seizures, her development was significantly delayed; she walked later than her siblings and struggled to form sentences, speaking only a handful of single words by age five. When the doctors examined her, they found the telltale signs of the disorder on her skin: small, red bumps clustered around her nose and cheeks, and a pale, ash-leaf-shaped spot on her face. These skin features are often the most visible clues of the condition. To look deeper, the medical team used magnetic resonance imaging, a powerful camera that creates detailed pictures of the brain without using radiation. The images revealed multiple hard spots and unusual lines in her brain, along with small bumps lining the fluid-filled spaces inside the skull. Further scans of her abdomen showed similar growths in both of her kidneys.

The second patient presented a very different picture, despite having the same underlying condition. She was a twenty-two-year-old woman who had suffered from seizures since she was eight years old. Unlike the young girl, she had completed secondary school and her thinking skills remained sharp, though she struggled with memory and concentration, likely due to the heavy medication she took to control her seizures. Her family history hinted at the disorder, with a cousin who had similar facial bumps and learning difficulties. When examined, she also displayed the characteristic red bumps on her face and a large pale patch on her back. Her brain scan showed the same distinctive patterns of hard spots and lines seen in the child, confirming the diagnosis. However, unlike the first patient, her kidney scans appeared normal, highlighting how the disease can affect different organs in different people.

What makes this report so significant is that both patients were diagnosed without a single genetic test. In many parts of the world, doctors rely on DNA analysis to confirm the presence of a mutation in the genes responsible for the disease. In Somalia, however, that technology is not available. The researchers showed that by strictly following international guidelines for diagnosis, which list specific physical and imaging signs as proof, a definitive diagnosis is possible. The guidelines state that finding two major signs, or one major sign plus several minor ones, is enough to confirm the disease. Both women and the child met these criteria through their skin findings, seizure history, and the clear images of their brains and organs.

The study also underscores the importance of looking at the whole body, not just the brain. The condition is a multisystem disorder, meaning it can touch the heart, lungs, kidneys, and eyes, not just the nervous system. In the young girl, the kidney scans revealed growths that needed monitoring, while the adult woman's heart and lungs were clear. This variation is common; the disease can be severe in one person and milder in another, even within the same family. The researchers noted that while the genetic cause is the same, the way it shows up can differ wildly. Some people face severe developmental challenges, while others, like the adult patient, maintain normal intelligence despite years of difficult seizures.

By sharing these cases, the authors hope to raise awareness among doctors and radiologists in similar settings. They argue that knowing what to look for on an ultrasound or a brain scan can lead to earlier detection and better care. Early diagnosis allows families to access the right specialists for seizures, skin care, and organ monitoring, which can prevent complications down the road. The report does not claim to have cured the disease or solved the genetic mystery, but it does prove that the tools to identify it are already in hand. In a world where advanced technology is not always accessible, the careful observation of the human body and the skillful use of imaging remain powerful ways to understand and treat complex conditions.
