I now have enough information from the textbooks plus my clinical knowledge to build a thorough diagnostic analysis. Let me compose the full response.
Clinical Analysis: 14-Year-Old Female with Sudden Loss of Consciousness, Bilateral Lower Limb Spasticity/Stiffness, and Hematemesis
This is a serious multi-system emergency. The combination of these three findings must be interpreted together, not separately.
Symptom Breakdown
| Finding | What It Points To |
|---|---|
| Sudden loss of consciousness | Neurological event, severe haemodynamic shock, hypoxia, hepatic encephalopathy |
| Lower limbs tight and stiff (spastic) | Bilateral upper motor neuron (UMN) lesion - cord or brain |
| Hematemesis (blood in vomit) | Upper GI bleed - oesophageal varices, peptic ulcer, Mallory-Weiss |
Leading Differential Diagnoses
1. HEPATOSPLENIC SCHISTOSOMIASIS + ESOPHAGEAL VARICEAL BLEEDING + PORTOSYSTEMIC ENCEPHALOPATHY (Most Likely Unifying Diagnosis in Endemic Regions)
This single unifying diagnosis can explain all three findings:
- Hematemesis: Schistosomal periportal fibrosis causes portal hypertension. Oesophageal varices rupture and cause massive haematemesis. Per Harrison's: "Patients with severe hepatosplenic disease and portal hypertension may develop esophageal varices...these patients may experience repeated bouts of hematemesis...death may result from massive loss of blood." - Harrison's, Hepatosplenic Schistosomiasis
- Loss of consciousness: Massive haemorrhage causes haemodynamic shock. Blood in the gut also precipitates hepatic/portosystemic encephalopathy (ammonia load from digested blood).
- Spastic lower limbs: Spinal schistosomiasis (neuroschistosomiasis) can deposit ova in the spinal cord causing transverse myelitis-like picture with spasticity.
This is especially relevant in Sub-Saharan Africa, East Africa, the Middle East, and tropical regions where Schistosoma mansoni and S. japonicum are endemic. The early hepatosplenic form is most common in children and adolescents.
2. TRANSVERSE MYELITIS (Neurological Cause of Spasticity + Secondary Events)
Acute transverse myelitis causes:
- Bilateral spastic lower limb weakness/stiffness (UMN pattern)
- Bowel/bladder dysfunction
- Sensory level
It can be caused by:
- Autoimmune (SLE, Sjögren's, NMO spectrum disorder)
- Post-infectious (viral, bacterial)
- Multiple sclerosis
Per Tintinalli's Emergency Medicine: "Transverse myelitis is a rare, devastating acute inflammatory process affecting a focal area of the spinal cord that may lead to rapid onset of irreversible paraplegia."
The loss of consciousness and hematemesis in this setting could be explained by:
- A seizure (from SLE or acute encephalomyelitis - ADEM) causing altered consciousness AND a Mallory-Weiss tear from vomiting/retching
- Or a concurrent separate upper GI bleed (stress ulcer)
3. PORTAL HYPERTENSION (Any Cause) + HEPATIC ENCEPHALOPATHY
Portal hypertension in adolescents is caused by:
- Extrahepatic portal vein obstruction (EHPVO) - most common cause in children in developing countries
- Cirrhosis (due to biliary atresia, Wilson's disease, hepatitis B/C, autoimmune hepatitis)
- Schistosomiasis (as above)
Ruptured oesophageal varices produce haematemesis → massive blood loss → loss of consciousness. The spastic lower limbs could reflect:
- Hepatic myelopathy (rare but documented in chronic portal hypertension - spastic paraparesis due to portosystemic shunting of toxins to the cord)
- Wilson's disease (causes liver disease + neurological spasticity/dysarthria)
4. WILSON'S DISEASE (Hepatolenticular Degeneration)
Wilson's disease typically presents in childhood/adolescence and can combine:
- Liver disease - hepatitis, cirrhosis, portal hypertension, haematemesis from varices
- Neurological signs - spasticity, dystonia, dysarthria, seizures, altered consciousness
- Look for: Kayser-Fleischer rings (golden-brown ring at corneal margin), low ceruloplasmin, elevated urinary copper
5. SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) - Adolescent Female
SLE is highly relevant in a 14-year-old female and can cause:
- Transverse myelitis - bilateral lower limb spasticity
- CNS lupus - seizures, coma (altered consciousness)
- GI involvement - lupus vasculitis causing intestinal/gastric bleeding, serositis
- Thrombocytopenia - bleeding tendency including haematemesis
Priority Immediate Assessment
Emergency Steps (Do These NOW)
- Secure airway, IV access × 2, blood pressure/pulse - assess for haemodynamic shock
- Urgent bloods: FBC, LFTs, coagulation (PT/PTT/INR), blood group & cross-match, serum ammonia, ceruloplasmin, ANA/anti-dsDNA, renal function
- Urgent upper GI endoscopy - to identify source and control variceal bleed
- IV fluid resuscitation + blood transfusion if shocked
- Proton pump inhibitor IV (e.g. pantoprazole) + terlipressin/octreotide if varices suspected
- MRI spine - urgent, to assess for transverse myelitis, cord compression, or spinal schistosomiasis
- Abdominal ultrasound - liver texture, portal vein diameter, splenomegaly, periportal fibrosis
- Neurological exam when stable - determine level of spasticity, reflexes, Babinski sign, sensory level
Red Flag Findings to Confirm Diagnosis
| Test/Finding | Points To |
|---|---|
| Splenomegaly + periportal fibrosis on US | Schistosomiasis / Portal HTN |
| Oesophageal varices on endoscopy | Portal hypertension (any cause) |
| Stool microscopy for ova | Schistosomiasis (Schistosoma eggs) |
| MRI spine: cord lesion/oedema | Transverse myelitis / Neuroschistosomiasis |
| Kayser-Fleischer rings | Wilson's disease |
| Low ceruloplasmin | Wilson's disease |
| ANA, anti-dsDNA positive | SLE |
| Elevated ammonia | Hepatic encephalopathy |
| Blood culture | Sepsis/bacterial meningitis with GI bleed |
Most Likely Working Diagnosis
Given the age (14F), combination of hematemesis + spasticity + sudden LOC, and assuming a tropical/endemic region:
Hepatosplenic schistosomiasis with portal hypertension causing oesophageal variceal haemorrhage (hematemesis + shock/LOC) PLUS spinal cord involvement (neuroschistosomiasis or hepatic myelopathy) is the single most unifying diagnosis. Wilson's disease or SLE must also be urgently excluded.

Important note: This analysis is for educational and clinical decision-support purposes. The patient requires urgent in-person evaluation by emergency medicine, gastroenterology, and neurology specialists immediately. Do not delay resuscitation pending a confirmed diagnosis.
