CT Brain Analysis

Key Findings

• The uppermost slices show normal-appearing cortex at the vertex level.
• Moving inferiorly, the lateral ventricles are notably enlarged bilaterally - both the frontal (anterior) horns and the bodies appear widened and rounded, which is disproportionate to the patient's apparent cortical sulcal widening.

• The lateral ventricles are markedly dilated, with enlarged and rounded frontal horns.
• The third ventricle appears widened in the midline.
• The temporal horns appear prominent as well.
• There is periventricular low density (hypodensity) surrounding the lateral ventricles in several cuts, which is the classic CT sign of transependymal CSF seepage - a hallmark of raised intraventricular pressure (active hydrocephalus).
• The cortical sulci appear relatively preserved (not as effaced as you'd see in diffuse cerebral edema), which is actually more consistent with hydrocephalus than global atrophy.

• The temporal horn dilation is confirmed bilaterally.
• The basal cisterns appear open/preserved, arguing against uncal herniation.
• No obvious large focal hyperdense lesion to suggest acute hemorrhage.
• The posterior fossa structures (cerebellum, brainstem) appear grossly normal in the bottom rows.

Radiological Impression

• Symmetric bilateral lateral ventricular enlargement (frontal horns, bodies, temporal horns)
• Third ventricular dilatation
• Periventricular hypodensity (transependymal edema) - this is particularly important as it suggests active/acute-on-chronic raised ICP, not just ex vacuo enlargement
• Relatively preserved cortex (not simply cerebral atrophy)

Differential Diagnosis

What I Do NOT See (Important Negatives)

• No obvious focal hyperdense area to suggest acute intracranial hemorrhage
• No clear midline shift
• No large hypodense infarct territory
• No obvious mass lesion
• Posterior fossa appears intact without tonsillar herniation

Clinical Correlation Required

1. Patient's age and clinical presentation (gait disturbance, dementia, incontinence in older patients = NPH; headache + papilledema in younger = obstructive hydrocephalus)
2. Contrast CT or MRI to rule out underlying cause (tumor, meningitis, aqueductal stenosis)
3. Formal radiology report - this analysis is for educational/informational purposes only and cannot substitute for a board-certified radiologist's reading

Patient Clinical Summary - Sabiha

Patient Demographics

• Name: Sabiha
• Age: 32 years old
• Gender: Female
• DOB: 06 June 1992
• Address: Mardan, Pakistan
• Date of Admission: 02 July 2026

Primary Diagnosis on Admission

Clinical History

Background

• Known asthmatic - currently on Combiair 400/12 mcg (Formoterol + Budesonide combination inhaler)
• History of recurrent chest infections
• 1 month prior she was admitted to the same hospital for right-sided pneumothorax - underwent therapeutic aspiration at that time

Presenting Complaints (Current Admission)

1. Cough
2. Fever - on/off
3. Right-sided pleuritic chest pain
4. Chest congestion
5. Weight loss
6. Anorexia
7. TB Contact positive (she has had known exposure to a TB patient)

Vitals on Admission

Examination Findings

• Bilateral wheeze (consistent with underlying asthma)
• Decreased breath sounds on the right side - consistent with the right-sided pleural effusion
• Pleural fluid R/E (routine examination) - Done

Laboratory Results - Analysis

Chemical Pathology

Hematology - Trend Analysis (Critical)

• The WBC of 29,200 on 23-May was severely elevated - this represents a major acute bacterial/inflammatory response (possibly pneumothorax-related infection or empyema)
• The shift from neutrophilia → lymphocytosis over time is important and can be seen with:
  • Resolving bacterial infection + superimposed TB (TB tends to produce lymphocytosis)
  • Treatment response
• Microcytic hypochromic anemia (low Hb, MCV, MCH with elevated RDW) is consistent with iron deficiency anemia - commonly seen with chronic disease and anorexia
• Abs Neutrophils (23.8 on 23-May → 6.5 on 02-Jul) confirms the dramatic fall in neutrophil count - treatment is working

Clinical Impression

Most Likely Diagnosis: Pulmonary Tuberculosis with Tuberculous Pleural Effusion (Right-sided, Septated)

1. TB contact positive - stated explicitly in the progress note
2. Symptoms classic for TB: chronic cough, fever (on/off), weight loss, anorexia
3. Right-sided septated pleural effusion - septation is characteristic of TB or complicated parapneumonic effusion
4. Prior pneumothorax - spontaneous pneumothorax in young adults can be the first presentation of apical TB
5. Lymphocyte shift in recent CBC - TB pleural effusions classically show lymphocyte predominance
6. Microcytic anemia - consistent with chronic disease/TB
7. Recurrent chest infections in a young woman - TB must always be at the top of the differential in endemic areas like Mardan, KPK, Pakistan
8. The consultant noted "TB-Contact +" specifically in the progress notes

Co-existing Condition: Bronchial Asthma

• Already on Combiair (budesonide/formoterol)
• Bilateral wheeze on examination
• B/L wheeze can also have a component from TB endobronchial involvement

Management Plan (As Documented)

1. Admit to pulmonology ward
2. CXR (PA view) - chest X-ray
3. Ultrasound chest - to characterize the effusion better and guide drainage
4. Sputum GeneXpert (MTB/RIF) - rapid molecular test for TB - this is the key diagnostic test
5. CBC, RFTs, LFTs, RBS - baseline labs (already done)
6. Pleural fluid R/E - already done as of 03/07 round

• "Pleural fluid R/E - Done"
• "Chest: B/L wheeze, Decrease air entry (Right)"
• "CVS: S1S2+0"
• Plan includes Sips + O₂ (likely sips of fluids + oxygen therapy)

The patient requires formal microbiological confirmation (GeneXpert, pleural fluid ADA, culture) before initiating anti-TB therapy (HRZE regimen).
