Pulmonary Artery Pseudoaneurysm (PAP) is a rare but potentially fatal cause of haemoptysis, which often remains unsuspected by both clinicians and radiologists. Traditionally, infections like tuberculosis and bacterial endocarditis have been associated with the development of PAPs. However, additional causative factors like trauma, neoplasia, pulmonary hypertension and vasculitis are also to be considered. With the advent of the novel Coronavirus (COVID-19), attempts have been undertaken to study its multisystem implications. Also, a strong correlation has also been established between COVID-19 and fungal infestation of the paranasal sinuses and lung parenchyma. Hence, PAP should be suspected in post-COVID patients who develop new-onset haemoptysis or new focal consolidation on imaging. Imaging investigations like chest radiograph, CT chest, and CT Pulmonary Angiography help in the establishment of a diagnosis and assessment of the relevant anatomy, which aid in the classification of the PAP. Management strategies include endovascular treatment, surgical resection or conservative approach in form of prolonged antimicrobial therapy. Interventional radiological procedures like endovascular embolisation are especially useful in vitally unstable cases of massive haemoptysis who are poor surgical candidates. Our case highlights the unique presentation of pulmonary arterial pseudoaneurysm induced by a post-COVID-19 fungal infection.
PMDS (persistent Müllerian duct syndrome) is a rare disorder of sex development characterised by the presence of Müllerian duct remnants in a phenotypically male individual with a 46XY karyotype. Radiological investigations play a crucial role in diagnosing and characterising this condition. Ultrasound and MRI are the modalities of choice. They help to non-invasively localise the gonads and Müllerian duct derivatives. Broadly, PMDS has two anatomical variants: male type and female type. The case report presented here does not fit into these classically described variants and can be called a variant of the female type. There is a risk of infertility and malignant transformation of undescended testis and Müllerian duct derivatives in cases of PMDS. Hence, management is focused on preventing these risks. Surgical intervention involves orchidopexy, removal of Müllerian duct derivatives and inguinal hernia repair.

Lipomatosis of peripheral nerves, or fibrolipomatous hamartoma (FLH), is a rare, benign condition characterized by fibrofatty overgrowth within the nerve sheath. While it most commonly affects the median nerve, involvement of the dorsal and plantar nerves of the foot is extremely rare. We report a case of a 28-year-old female presenting with a painless, gradually enlarging swelling of the right foot, which had been present since childhood. Ultrasound showed diffuse fusiform hyperechoic fatty tissue with hypoechoic interspersed nerve fascicles, avascular on Doppler. Magnetic resonance imaging (MRI) revealed a well-defined lesion extending along the course of the dorsal and plantar nerves, appearing hyperintense on T1- and T2-weighted images, with suppression on fat-saturated sequences. Internal low-signal strands created a “coaxial cable” appearance, typical of FLH. Non-contrast computed tomography (CT) confirmed a lobulated fat-density lesion with soft tissue strands. This case represents a post-operative presentation, which may alter the typical imaging appearance and pose diagnostic challenges. High-resolution ultrasound and CT were used as adjunct modalities, adding value by confirming fascicular architecture, fat attenuation, and associated post-surgical bony changes. Recognition of relevant differentials, including macrodystrophia lipomatosa and stump neuroma, is important in such settings to avoid misdiagnosis and unnecessary intervention.
