A 9-day-old neonate with giant scalp abscess: A case report.

RATIONALE: Neonatal scalp mass is common in clinical practice. After birth canal compression and traction force, a cephalohematoma is usually found. However, cephalohematoma with abscess is extremely rare and dangerous. So far, there have been no reported cases of multidrug-resistant Escherichia coli infections in giant neonatal scalp hematoma.

PATIENT CONCERNS: We present a 9-day-old with a scalp abscess and a large scalp defect that remained after surgical drainage.

DIAGNOSIS: Physical examination showed a giant mass suggestive in the parietal region. B-mode ultrasound indicated the scalp mass was liquid. The early diagnosis was massive scalp hematoma. During conservative treatment, purulent fluid flowed from the mass region through a rupture in the scalp. MR examination showed the scalp had burst and no abnormalities were found in the medial side of the skull and skull.

INTERVENTIONS: The surgeon opened up the mass and removed necrotic tissue. The scalp was severely damaged; the aseptic auxiliary materials that we made in-house were used to gradually reduce the defect.

OUTCOMES: The scalp was healed by anti-infection treatment and frequent changing of the dressings. The patient was successfully treated without two-stage surgery. There were no complications.

LESSONS: A scalp hematoma is a potential site of infection. Anti-infection treatment and surgery are necessary to correct infected scalp hematoma. This work offers a new way of treating other large scalp defects.
