- 9 min read
Season 2 of Doc continues to deliver complex medical mysteries that challenge Dr. Andrea Fanti and his team at the Policlinico Ambrosiano. This season delves into rare pathologies, intricate surgical interventions, and the profound impact of medical history on patient outcomes. Below is a comprehensive review of the key medical diagnoses and conditions presented in each episode.
Episode 1
Anomalous Pulmonary Vein and Pulmonary Artery Intimal Thickening
The season opens with the emotionally charged case of Rosie Cruz, a young patient on the transplant list for six years. While a donor heart finally becomes available, a pre-transplant CT scan reveals a suspicious "spot" on her left lung. Dr. Amy Larsen’s team initially investigates this as a potential lung abscess or systemic infection—either of which would disqualify Rosie from the life-saving surgery. Under extreme duress during a hospital hostage situation, Dr. Larsen performs an ultrasound-guided drainage, confirming the spot is a localized abscess containing gray pus.
However, the final diagnosis is far more devastating: Rosie suffers from an anomalous pulmonary vein combined with thickening of the intimal lining of her pulmonary arteries. Dr. Larsen had previously identified that these abnormalities would make a heart transplant fatal, as the new organ would trigger massive pulmonary hypertension that Rosie’s lungs could not withstand. The transplant is deemed impossible, and the focus shifts to palliative care, allowing Rosie a final moment of consciousness to say goodbye to her father.
Other Medical Diagnoses and Conditions Discussed
Retrograde Amnesia: Loss of memory for events prior to a specific trauma, erasing years of personal history.
Gunshot Wound with Heavy Arterial Bleed: Traumatic injury causing rapid, life-threatening hemorrhaging from a major vessel.
Preterm Labor and Premature Rupture of Membranes: Rupture of the amniotic sac before the 37th week, risking fetal lung maturity.
Lung Abscess: A localized collection of pus in the lung tissue, treatable via drainage.
Systemic Infection: Widespread infection that contraindicates organ transplantation.
Femoral Artery Injury: Trauma to the primary leg artery requiring immediate surgical repair to prevent fatal blood loss.
COVID-19: Viral respiratory illness noted in medical history as preventing family presence during end-of-life care.
Left-Sided Heart Failure and Fluid Overload: Inability of the left heart to pump effectively, causing pulmonary backup and dropped oxygen saturation.
Umbilical Cord Compression: Restriction of blood flow to the fetus during labor, causing heart rate decelerations.
Episode 2
Pseudocyesis and Stromal Tumor
Megan presents with a rounded belly and pronounced breast changes, appearing seven months pregnant. Ultrasound reveals a mass but no fetus, and bloodwork confirms she is not pregnant. The diagnosis is pseudocyesis, a rare psychological condition where the body physically mimics pregnancy. The hormones produced by this delusion feed a stromal tumor in her abdomen. During a biopsy, a "hormonal storm" triggers myoclonic tetany and tachycardia, stabilized with IV lorazepam. Treatment involves surgical removal of the tumor and psychological intervention to help Megan grieve.
Lipoma-Induced Intractable Hiccups
Adam suffers from debilitating intractable hiccups for 11 days. After ruling out neurological causes, the team traces the issue to a lipoma—a fatty growth located at the nexus of the brachial plexus and phrenic nerve. The mass irritates the nerve, causing chronic hiccups. Surgical excision cures the condition while preserving the patient’s body art.
Other Medical Diagnoses and Conditions Discussed
Chronic Kidney Failure: Gradual loss of renal function requiring medication management (e.g., ACE inhibitors).
Heart Failure with Low Ejection Fraction: Ineffective pumping of the heart muscle, necessitating inotropic support.

Kevin Cross, an amputee, presents with necrotic tissue and infection in his stump. Investigation reveals a hip replacement using a cobalt alloy from 12 years prior. The diagnosis is metallosis, caused by metal-on-metal degeneration leading to systemic toxicity and an AV fistula. Treatment involves a minimal stump revision and replacement of the faulty hip hardware.
Drug-Induced Hepatitis and Ventricular Tachycardia
Claire Pinto, an MS patient, is admitted with drug-induced hepatitis after replacing traditional medication with herbal supplements and experimental stem cell injections. An unauthorized intrathecal stem cell injection triggers ventricular tachycardia (V-tach) due to her compromised liver. She is stabilized with defibrillation, beta-blockers, and amiodarone.
