Unmasking portal hypertension: A case of diagnostic distraction by chronic hemoptysis

The diagnosis of portal hypertension (PHT) secondary to chronic portal vein thrombosis (PVT) relies on recognizing key clinical signs like splenomegaly and cytopenias. Ancillary symptoms, such as chronic hemoptysis, can act as diagnostic distractors, delaying the identification of the underlying pathology. This case report highlights the crucial role of fundamental clinical skills in elucidating a complex diagnosis obscured by a misleading symptom.

A 40-year-old female presented with an eight-year history of hemoptysis, an ancillary symptom that had led to multiple inconclusive pulmonary evaluations. The definitive diagnostic clues were found on our assessment: a palpable spleen on physical examination and severe pancytopenia on routine laboratory tests. These findings established a diagnosis of PHT, which was subsequently confirmed by imaging to be caused by idiopathic chronic PVT, with secondary development of a cavernous transformation of the portal vein (CTPV).

The educational value of this case lies in its demonstration of a diagnostic odyssey. The ancillary symptom of hemoptysis obscured the classic signs of PHT for years. The final diagnosis was achieved not by investigating the rare symptom further, but by synthesizing it with the fundamental findings from the physical exam and labs. The hemoptysis, which resolved completely after endoscopic variceal ligation (EVL), was retrospectively explained as a consequence of PHT.

This case serves as a powerful reminder that ancillary symptoms can be misleading. The foundation of an accurate diagnosis often rests upon a thorough physical examination and interpretation of basic laboratory tests, which can reveal the true underlying condition.
