#MedX A term newborn has excessive salivation and choking with the first feed.
Attempts to pass an orogastric tube fail, and the tube coils in the proximal esophagus on the chest radiograph. There is a gas-filled stomach and bowel, and the abdomen is not scaphoid.
The radiograph shows the coiled tube in a blind-ending proximal esophageal pouch, with air present throughout the gastrointestinal tract.
What is the diagnosis for this case?

A premature 10-day-old infant, born at 28 weeks, develops abdominal distension, bilious gastric residuals, and blood-streaked stools. He is lethargic, with abdominal erythema and a tender, tense abdomen. Laboratory values show thrombocytopenia and metabolic acidosis.
The abdominal radiograph shows dilated loops of bowel with linear and bubbly lucencies within the bowel wall (pneumatosis intestinalis) and a branching pattern of gas in the portal vein. Free intraperitoneal air is absent.

Necrotizing enterocolitis.
Immature gut barrier, bacterial invasion, and ischemia produce mural gas and, when severe, portal venous gas or perforation. Pneumatosis is the hallmark radiographic finding and is often first seen in the right lower quadrant. Management is bowel rest, broad-spectrum antibiotics, and serial radiographs; free air or clinical deterioration indicates the need for surgical resection of necrotic bowel.

A 5-day-old term infant develops sudden bilious vomiting and a distended abdomen. The baby is irritable, with a scaphoid epigastrium and bloody stools. An upper GI contrast study shows the duodenojejunal junction to the right of the midline, with the proximal jejunum spiraling around the superior mesenteric artery axis (corkscrew sign). The distal bowel fails to fill promptly.

Midgut volvulus due to malrotation.
Incomplete rotation and fixation of the intestine leave a narrow mesenteric base, allowing the midgut to twist around the SMA and produce closed-loop ischemia. Bilious vomiting in a neonate is a surgical emergency until proven otherwise. The corkscrew appearance on upper GI series is diagnostic; Doppler ultrasound may show the whirlpool sign of twisted mesenteric vessels. Immediate laparotomy for detorsion and Ladd鈥檚 procedure is required to restore perfusion and prevent short-gut syndrome.

The classic mammographic appearance of a fibroadenoma is a well-circumscribed, round or oval, radio-dense mass with smooth or microlobulated margins, often surrounded by a thin lucent halo (the halo sign).
As fibroadenomas involute with age and hyalinize (especially in postmenopausal women), they typically develop coarse, chunky calcifications known as "popcorn" calcifications.

The correct answer is B. Pre-eclampsia.
Explanation:
Diagnostic Criteria: Preeclampsia is defined as new-onset hypertension (systolic \ge 140\text{ mmHg} or diastolic \ge 90\text{ mmHg}) occurring after 20 weeks of gestation, accompanied by proteinuria (\ge 1+ on dipstick or \ge 300\text{ mg} per 24 hours) or signs of end-organ dysfunction.
Severe Features Present: This patient exhibits blood pressure \ge 160/110\text{ mmHg} along with cerebral/visual symptoms (headache, visual flashes) and brisk reflexes (hyperreflexia), indicating preeclampsia with severe features.

The hallmark MRI appearance consists of asymmetric, multifocal T2/FLAIR hyperintense subcortical white matter lesions with U-fiber involvement, producing sharp scalloped outer margins and hazy inner borders, typically without mass effect or enhancement.
