What is the recommended acute treatment for a young adult male who, after recent heavy alcohol and methamphetamine (shabu) use, presents with stroke‑like symptoms, gait disturbance, a CT scan suggestive of stroke, MRI indicating possible cerebral aspergillosis, and vomiting a parasite suggestive of neurocysticercosis?

Immediate Management: Prioritize Neurocysticercosis Treatment While Addressing Acute Complications

Ang pasyente kinahanglan dayon nga ma-manage ang elevated intracranial pressure gamit ang corticosteroids ug dili pa maghatag ug antiparasitic drugs hangtod stable ang kondisyon, human niini ihatag ang albendazole ug praziquantel combination therapy tungod sa multiple viable cysticerci, uban sa antiepileptic drugs kung adunay seizures. 1

Algorithmic Approach to This Complex Case

Step 1: Stabilize and Assess for Elevated Intracranial Pressure

Ang unang lakang mao ang pag-assess kung aduna bay signs sa elevated intracranial pressure o diffuse cerebral edema:

• Fundoscopic examination - kinahanglan dayon buhaton para ma-detect ang papilledema 1
• Kung adunay untreated hydrocephalus o diffuse cerebral edema: DILI UNA MAGHATAG UG ANTIPARASITIC DRUGS 1
• Manage elevated ICP first gamit ang corticosteroids para sa cerebral edema, o surgical approach kung hydrocephalus 1

Step 2: Address the Methamphetamine-Related Stroke Component

Ang stroke-like symptoms human sa shabu (methamphetamine) use mahimong:

• Hemorrhagic stroke (mas common sa meth use) 2, 3
• Ischemic stroke secondary to vasospasm, accelerated atherosclerosis, o cardiomyopathy 2, 4

Standard stroke protocols apply: Supportive care, blood pressure management, pero ang specific thrombolytic therapy depende sa imaging findings ug timing 5. Ang meth-associated strokes walay specific treatment lahi sa standard stroke management 2.

Step 3: Confirm Neurocysticercosis Diagnosis

• Both MRI and non-contrast CT scan kinahanglan buhaton 1
• Serologic testing gamit ang enzyme-linked immunotransfer blot (EITB) - dili crude antigen ELISA tungod sa poor sensitivity/specificity 1
• Ang parasite nga gi-vomit strongly suggests neurocysticercosis diagnosis

Step 4: Rule Out Cerebral Aspergillosis

Ang MRI findings suggestive sa aspergillosis kinahanglan i-investigate, especially kung immunocompromised (though diabetes alone rarely causes invasive aspergillosis) 6. Pero ang vomited parasite strongly points to neurocysticercosis as primary diagnosis.

Step 5: Antiparasitic Treatment Protocol (Once ICP Controlled)

Kung WALA elevated ICP ug stable na ang patient:

For multiple viable parenchymal cysticerci (based sa vomited parasite ug likely multiple lesions):

• Albendazole 15 mg/kg/day (divided into 2 daily doses, maximum 1200 mg/day) PLUS
• Praziquantel 50 mg/kg/day (divided into 3 daily doses)
• Duration: 10-14 days
• Ihatag with food 1

Corticosteroids MUST be given concomitantly - start BEFORE antiparasitic therapy para ma-prevent ang inflammatory response 1

Step 6: Antiepileptic Drug Management

Kung adunay seizures (common sa NCC):

• Start antiepileptic drugs immediately 1
• Choice based on local availability, cost, drug interactions 1
• Continue until seizure-free for 6 months ug resolved na ang lesions, UNLESS adunay risk factors for recurrence (calcifications, breakthrough seizures, >2 seizures) 1

Step 7: Pre-Treatment Screening

Before starting prolonged corticosteroids:

• Screen for latent tuberculosis 1
• Screen or give empiric treatment for Strongyloides stercoralis (especially kung gikan sa endemic area) - important kay ang steroids makacause ug hyperinfection 1

Step 8: Monitoring During Treatment

• Monitor for hepatotoxicity and leukopenia kung mag-albendazole >14 days 1
• Repeat MRI every 6 months until resolution of cystic lesions 1

Critical Pitfalls to Avoid

1. NEVER give antiparasitic drugs kung adunay untreated elevated ICP - this can worsen cerebral edema ug cause herniation 1

2. NEVER start antiparasitic drugs without corticosteroids - ang inflammatory response sa dying parasites makacause ug severe complications 1

3. NEVER skip fundoscopic exam - intraocular cysticerci mahimong ma-blind kung ma-treat ug antiparasitic drugs 1

4. NEVER use albendazole alone kung >2 cysts - combination therapy significantly better 1

5. NEVER assume stroke is only from meth - ang NCC mismo mahimong cause ug ischemic stroke through vascular compression 7

Addressing the Aspergillosis Concern

Ang MRI findings suggestive sa aspergillosis unusual sa immunocompetent patient. Kung truly aspergillosis (needs tissue diagnosis o culture), ang treatment mao ang amphotericin B 6. Pero ang clinical picture (vomited parasite, endemic area, young patient) strongly favors neurocysticercosis as primary diagnosis. Ang aspergillosis co-infection rare kaayo unless severely immunocompromised.

Substance Use Considerations

• Abstinence from continued methamphetamine use essential para sa secondary stroke prevention 2
• Ang prolonged meth withdrawal kinahanglan i-address 2
• Screen for other complications: cardiomyopathy, arrhythmias, infective endocarditis (kung injection drug use) 2, 4

Follow-up Strategy

• Clinical monitoring for seizure recurrence
• MRI every 6 months until complete resolution 1
• Kung persistent lesions after 6 months: consider retreatment 1
• Household screening for tapeworm carriage (public health issue) 1

Ang kini nga case complex kaayo ug kinahanglan ug expert consultation - ang IDSA/ASTMH guidelines specifically recommend low threshold for expert consultation sa neurocysticercosis cases 1.
