Precursor T-cell acute lymphoblastic leukemia presenting with bone marrow necrosis: a case report

Bone marrow necrosis secondary to metastatic adenocarcinoma revealed by 18F-FDG PET/CT: A clinical case report

RATIONALE

Bone marrow necrosis (BMN) is a rare malignancy-associated hematologic disorder characterized by necrosis of myeloid and stromal marrow elements with preservation of cortical bone.

PATIENT CONCERNS

A 43-year-old female complaining of dizziness and vaginal bleeding for more than 2 months was presented to our department.

DIAGNOSIS

Due to the laboratory test results, radiographic findings, especially F-fluoro-2-deoxy-D-glucose (F-FDG) positron emission tomography/computed tomography (PET/CT) which revealed that bone marrow was characterized by diffuse F-FDG uptake with extensive central photopenia, and pathologic results, she was diagnosed with metastatic adenocarcinoma accompanied with BMN. And the cancer most likely originated from reproductive system or breast.

INTERVENTIONS

There was no effective interventions for her before knowing the accurate origin of adenocarcinoma.

OUTCOMES

Two weeks later, unfortunately, she died.

LESSONS

F-FDG PET/CT is a useful diagnostic modality in patients with BMN. Malignant tumor should always be considered in patients with extensive BMN, even in young people.
