Pulmonary capillary haemangiomatosis in a premature infant

Hydrops Fetalis and Congenital Pulmonary Capillary Haemangiomatosis in a Premature Infant - A Case Report and Literature Review

Pulmonary capillary haemangiomatosis (PCH) is a rare disorder of the lung, well described in adult literature. PCH is characterized by capillary proliferation, infiltrating the interstitium and alveolar walls. This leads to development of respiratory distress and to end-stage pulmonary hypertension. Mostly young adults are affected. The affection of newborn is described in less than ten cases in literature in the past forty years. PCH is a mostly deadly ending disease. We present a preterm born infant with antepartal diagnosed hydrops fetalis, who died 30 minutes after birth. Autopsy revealed PCH as lethal reason and not cardial disease as presumed before.

Assessment of pulmonary hypertension what CT and MRI can provide

RATIONALES AND OBJECTIVES

Pulmonary hypertension (PH) is a life-threatening condition, characterized by elevated pulmonary arterial pressure, which is confirmed based on invasive right heart catheterization (RHC). Noninvasive examinations may support diagnosis of PH before proceeding to RHC and play an important role in management and treatment of the disease. Although echocardiography is considered a standard tool in diagnosis, recent advances have made computed tomography (CT) and magnetic resonance (MR) imaging promising tools, which may provide morphologic and functional information. In this article, we review image-based assessment of PH with a focus on CT and MR imaging.

CONCLUSIONS

CT may provide useful morphologic information for depicting PH and seeking for underlying diseases. With the accumulated technological advancement, CT and MRI may provide practical tools for not only morphologic but also functional assessment of patients with PH.

A unique case of a giant congenital pulmonary hemangioma in a newborn

Congenital pulmonary hemangiomas are extremely rare lesions. We present a unique case of a giant congenital pulmonary hemangioma in an otherwise healthy newborn who presented with respiratory distress at birth. This was managed with resection after an unsuccessful trial of nonoperative management. The clinical, radiographic, and pathologic features of this unique case are discussed in the context of a review of the literature.

Pulmonary capillary hemangiomatosis imaging findings and literature update

Pulmonary capillary hemangiomatosis (PCH) is a rare and an only recently described vascular disease. As one of the causes of primary pulmonary hypertension, the need for the establishment of helpful diagnostic radiological criteria for this condition has become imperative. However, the unstable hemodynamic condition of patients with primary pulmonary hypertension often denies pathological sampling as a definitive diagnostic tool. This diagnostic dilemma can be fatal to those patients with PCH treated for pulmonary hypertension because a fatal pulmonary edema may occur. We report a case of PCH in a 26-year-old patient who died of severe circulatory compromise while undergoing transplant evaluation. A discussion of the computed tomography findings, a review of the pathological features, and a review of the relatively limited imaging literature available on this subject are conducted.
