Diagnosis of pulmonary adenoid cystic carcinoma using multimodal ultrasound imaging technology: A case report.

RATIONALE

Pulmonary adenoid cystic carcinoma (PACC) is an exceedingly uncommon malignant tumor originating from salivary glands.

PATIENT CONCERNS

We present a case of primary PACC with multiple lung metastases in a 48-year-old male patient.

DIAGNOSIS

Diagnosis involved grayscale ultrasound, shear wave elastography, contrast-enhanced ultrasound, and ultrasound-guided percutaneous lung biopsy, all conducted in a one-stop manner, and confirmed by pathological examination.

INTERVENTIONS

Treatment was recommended after the diagnosis was confirmed, but was not accepted.

OUTCOMES

With telephone follow-up, the patient survived.

LESSONS

PACC is an exceedingly uncommon malignant tumor originating from salivary glands. Compared to other cases, this case highlights the potential of multimodal ultrasound imaging for diagnosing lung tumors.
