Neonatal cervical teratoma with critical airway compression: A case report.
Article in Radiology case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Neonatal cervical teratomas are rare congenital tumors that may cause life-threatening airway compromise despite their predominantly benign histology. We report a male neonate born at 38 weeks of gestation by elective Caesarean section due to a large prenatal neck mass and polyhydramnios. Shortly after birth, the infant developed severe respiratory distress requiring endotracheal intubation following transfer to our institution. Contrast-enhanced computed tomography demonstrated a 10 × 12 × 13.5 cm heterogeneous mass centered within the oropharyngeal/oral cavity and submandibular spaces with extension into the anterior cervical region and upper chest wall, containing cystic and solid components, fat, and calcifications, causing marked tracheal compression and displacement without intracranial extension. Preoperative serum alpha-fetoprotein (AFP) was 14,432.78 ng/mL. Complete surgical excision was performed on day 4 of life through a transverse cervical incision while preserving major cervical structures. Histopathological examination confirmed mature cystic teratoma composed of mature glial tissue, cartilage, adipose tissue and squamous epithelium without immature elements. The patient had a good postoperative recovery and was discharged on the 35th postoperative day. Follow-up evaluation revealed normal serum calcium and parathyroid hormone levels, while thyroid function tests indicated subclinical hypothyroidism needing levothyroxine replacement therapy. At 5 months, there was no recurrence and AFP had decreased to 44.64 ng/mL. This case underscores the importance of early airway stabilization, detailed imaging, complete surgical excision, and multidisciplinary postoperative surveillance in neonatal cervical teratomas.
